The Nubia Sandstone Nubia Group , Western Desert, Egypt An Overview

No information was given about the outcropping of the Nubia sandstone in the Great Sand Sea in the Western Desert of Egypt and actually very scarce and insufficient information has been written on the geology of the Great Sand Sea. Since 1931 the Great Sand Sea has been described as being formed of many parallel longitudinal sand dunes which cover ~72000 km² and are bounded in the south by the Gilf El Kebir Nubia Sandstone Plateau and in the north by Siwa Oasis. However, recently it has been found by the author and his collaborators that the rock units exposed on surface in the Great Sand Sea are belonging to the younger members of the fluviatile Cretaceous Nubia Sandstone Group. They are not covered by younger marine consolidated deposits but only with a thin veneer of accumulations of free sands originating from the disintegration and breakdown of the Nubia Sandstone bedrock, thus obscuring the original bedrock. The area exhibits a long history of predominantly continental sandstone accumulation and continuous subsiding during the geologic history so that the sequence attains a thickness more than 3500m in the subsurface. The exposed Nubia Sandstone rocks have been formed in different geomorphologic features such as longitudinal parallel sandstone ridges separated by wide flat sandstone tracks, sandstone plateaus and domes, sandstone depressions, plains and valleys. These results make it necessary to review the surface distribution and the lithostratigraphic change both stratigraphic and geographic of the Nubia Group in the Western Desert of Egypt.

Extraction of Valuable Elements from Ash of Fuel Shale of the Aktau and Sangruntau Deposit

Hydrometallurgical methods are aimed at leaching for the extraction of valuable components into a sulfuric acid solution, as well as selective extraction on ion exchange resins by the method of sorption and precipitation of valuable components such as vanadium oxide, molybdenum oxide, zinc oxide and the amount of REE oxide and uranium oxide. The presented methods are not implemented on an industrial scale, since there is no processing of oil shale in the Republic. A prospective scheme for processing ash from oil shale deposits has been analyzed. It includes the addition of sodium chlorine to the oxidative roasting process, the resulting ash is leached in vats with sulfuric acid 150 g l, at room temperature, S L= 1 5, duration 60 minutes. The resulting metal bearing sulfuric acid solution is filtered and sent to sorption, as well as precipitation. The extraction of metals into solution is, vanadium 84.3 85.6, molybdenum 95.4 88.1, zinc 69.6 71.1, uranium 60.3 64.9 and the amount of REE 66.2 49.2, respectively. For the extraction of metals from productive solutions of leaching ash from oil shale deposits of Aktau and Sangruntau, the following ion exchange resins of the Anglia company PUROLITE were used for vanadium grade A 109 extraction 79 81 , for molybdenum grade A 100 extraction was more than 84 86 , uranium grade A 560 extraction 81 79 and for zinc S 984 extraction 75 71 . Carried out precipitation to extract REE and received 18 content of the amount of REE.

A Pilot Study on the Consumption of Mainstream Media and it’s Negative Impact on Teenagers
Mass media is a very powerful tool to influence the minds of a teenager. Teenagers are in that stage of growing up where everything influences them. Todays Socialization is turned as a chaos through apps From Facebook to Tinder, Instagram to WhatsApp, YouTube to Ticktock everyone has been socialized. As per Psychological point view... teenagers, young generation are been exploited in the name of Socialization. People under these categories are involved Anti National, Anti Social activities and Crime based activities like Drug abduction, Rape Molestation, Kidnap Murder. The Present Study tries to focus on the x facts of this Problem and try to understand how and what kind of role is played by the media which pressurize the young generation. This Study is Literally focused on the impact of Mainstream Media which includes Social Media, Internet, Entertainment Genres like Cinema, TV Soaps, Reality Shows, YouTube Videos, Entertainment Apps etc. on Young Generation or Teenagers on Negative Side.

Geochemical Fractionation of Lanthanides in Stream Sediments around Bwanebwa Area Pan African Fold Belt Cameroon

Fifteen stream sediment samples were collected in Bwanebwa area, situated southwestern part in the central domain of the Pan African Fold Belt in Cameroon. Samples were analyzed by Aqua Regia Inductive Coupled Plasma Mass Spectrometry analytical technique. The chemical analyses revealed a wide variability of lanthanide concentrations REE = 1471.56 7674.2 ppm displaying a normal distribution pattern. Lanthanides show a high enrichment in La, Ce, Pr, Nd, and the proportion enrichment of REEs is still similar with increasing atomic number. The order of the average concentrations of REEs is Ce La Nd Pr Sm Gd Dy Er Tb Ho Yb Eu Tm Lu, which was different to that found in the Oddo Harkins rule, earth’s crust, upper continental crust, South China Sea, mean REE values in oceanic crust, Redang Island Marine Sediment in Terengganu Coastal Waters, Bayan Obo ores, Edéa, suggesting that REEs set up a complex group. The LREE HREE ratio 31.57 35.24, av. = 32.82 showed that the content of LREE 1425 7449.8, av. = 3699 is significantly higher than that of HREE 46.56 224.4, av. = 112.07 . LREEs account for 97.06 of the total REEs and this percentage is in agreement with the trend that was observed in the earth’s crust and in the Bayan Obo ores. Chondrite normalized REE distribution patterns are identical, indicating the consistency of geochemical distribution of REEs in stream sediments. They are strongly fractionated, with LREEs significantly fractionated LaN YbN = 11.74 27.93, av. = 21.04 relative to HREEs GdN YbN = 7.40 16.69, av. = 13.35 , implying that HREEs are more soluble and more complex than middle or LREE and are more strongly absorbed on most substrates. Positive Ce anomaly Ce Ce = 1.04 1.07 and negative Eu anomaly Eu Eu = 0.097 0.17 were observed, indicating that di erentiation occurred between Ce, Eu and other lanthanides. Therefore the positive Ce anomaly recorded represents an enrichment of Ce compared with its neighboring elements. A five factor model of the REEs that accounts for 1.998 of the total data cumulative variance have been observed, with the communality values 0,996 1 reflecting stronger community structure. Principal component analysis results in five components that explain 100 of the total variance, with the placement of elements in three major principal components, in which elements scattering in the rotated space displaying their mutual association. The results provide evidence for similar input sources and common geochemical characteristics of REEs. Lanthanide concentrations in Bwanebwa area were of geogenic origins and not influenced by anthropogenic sources. The abundance of REEs is related to the lithology made up of granites and associated pegmatites. Cerium shows the highest average content of REEs, followed by La, Nd, Pr, Gd, Sm, hence pattern of Ce distribution shows higher than the other lanthanides. LREEs La, Ce, Pr, Nd and Ga fall above the upper background threshold limit and are considered as anomalous. Therefore the results of this work serve as guide for lanthanides exploration in Bwanebwa area.

Physico Chemical and Bacteriological Quality of Water Sources in the Coast of Ndian, South West Region, Cameroon Health Implications

The study of water sources used by the population of Ndian for drinking with the exception of the Ekondo Titi beach was carried out by investigating 51 water sources. Due to the lack of pipe borne water in this area, the population is compelled to consume water from unprotected shallow aquifers and surface water sources, there by exposing the population to infections form of water borne diseases. In this perspective, the present study was aimed to check the suitability of these water sources for drinking. The bacteriological quality of the water sources was performed using the Most Probable Number MPN technique. Temperature, pH, electrical conductivity EC and total dissolved solids TDS were also determined. The pH values reflect slightly acidic, neutral and basic water sources. Sixty percent 60 of the ground water samples where slightly acidic 5.5  6.4 and out of the WHO 2011 guideline limit 6.5 8.5 for drinking water. This situation puts the inhabitants at risk to stomach ulcer. The electrical conductivity values 3.00 274 us cm for groundwater sources represents water experiencing slight mineralization. Based on the total coliform bacteria, 96 of water sources were polluted to grossly polluted 75 2400 MPN 100 ml and 4 excellent following the acceptable maximum limits prescribed by the World Health Organization Standards which exposes the population to water borne diseases such as typhoid, cholera and dysentery. The bacteria contamination of the water sources may result from the waste of pit toilets that intersect the water tables of shallow unconfined aquifers and also from poor sanitation practices carried out along stream channels and springs. Proper water treatment at household levels is highly recommended.

An Account of Field and Petrographic Characteristics of Granitic Rocks of Cherlapally Area, Nalgonda District, Telangana

Field geological and petrographic characteristics of granitic rocks of Cherlapally area, Nalgonda district, Telangana, within the eastern Dharwar craton are described in this paper. Field traverses revealed four types of granitic rocks in the study are viz., quartz diorite, granodiorite, monzogranite and syenogranite. The variations in the texture and mineralogical composition of these plutons are so distinct that the term migmatite' has to be applied, wherein mutual field relations always remain enigmatic. The complex nature of the batholiths is also evident from the structural fabrics observed in the present investigation.

A Study on effect of Geographical issues on Natural Disaster in India
Natural disasters and climate change are fast emerging as the most defining challenges of the 21st century. India`s unique Geo-climatic condition makes it highly susceptible to climate change and natural disasters. The country has observed significant anomaly in natural variability of temperature and rainfall patterns and has experienced more frequent and lethal disasters in recent decades. Almost unanimous but uneven temperature rise over the Indian subcontinent has propelled more energy in regional and local climate systems, and thus, has magnified climate anomalies and frequency as well as severity of natural disasters. The paper investigates the climate change and natural disasters propensities and highlights the climate change-disaster linkage in Indian context. It also identifies vulnerable areas and suggests some policy measures which may be of great help in reducing the impact of these catastrophes on society.

Reconstruction of European Geopolitics with a Special Reference to Mackinder's Heartland Theory

January 05, 2018 0
Reconstruction of European Geopolitics with a Special Reference to Mackinder's Heartland Theory
European geopolitics has been ever been a matter of discussion for the political geographers. The geostrategic theory of Halford Mackinder has helped in organising the thoughts in a proper way. Mackinder's theory was written under a tensed environment when European nations were preparing themselves for a great conflict either to safeguard their sovereignty or to glorify their nation.

The theory was changed by the author several times as European politics never stood still since 1904. This paper tries to review the great events of European history that led to even greater political rearrangements. Renaissance was the first leap towards modern Europe followed by Industrial Revolution when European nations formed colonies in Asian and African countries with an economic motive.

This eventually turned into a competition giving rise to dissatisfaction, aggression and discontent which ultimately led to World War I. Germany after the first war again arranged the arena for another war. The Second World War ended by inviting Cold War by dividing the world into two blocks; one around the Soviet Union and other one was United States. Gradually, Europe divided into two parts, Western Europe allied with the United States and Eastern Europe became the devotee of USSR. From that time, USA always tried to establish a policy which directly hamper the development of Russian territory specially reference to Germany.

As a result, during 1945 Germany was divided into two parts namely Western and Eastern Germany. At 1990s, Germany was reunited with the crumple of communism and a modern geopolitics was started. Germany was again the most powerful States under European Nation; consistently supports policies aimed at advancing EU-NATO cooperation.

USA in 2004 tried to establish world hegemony by military intervention in Eastern Europe, USSR and Central Asia to weaken their unity which might be a threat to American supremacy. So, with the different interventions of event, a very clear notion has come that the geographical proximity of the Pivot area still exists.

Assessment of the Engineering Properties and Suitability of Some Tropical Soils as Backfill Materials

November 24, 2017 0
Assessment of the Engineering Properties and Suitability of Some Tropical Soils as Backfill Materials
Little to none has been known about some soils excavated for backfilling purposes in Anambra State, Southeastern Nigeria. Thus, this study, which involved literature reviews, field sampling, and integrated geotechnical analyses, presents an assessment of their engineering properties and suitability as backfill (foundation, embankment, subgrade, and base) materials.

Eight soil samples (ABG, NIM, OZB, NKA, OKJ, ORK, ULI, and NBI) from eight borrow pits were studied. Grain-size analysis revealed that the eight soils are dominantly composed of medium-coarse grains. Laboratory USCS identified and grouped the soils into five '“ GP, SW, SP, SC and CL. Their permeability coefficients ranged from 4.22x10-6 to 4.34x10-4m/sec, hence they are permeable.

Compaction test revealed MDD range of 1.76'“1.94g/cm3, OMC range of 13.29'“17.10%, and bulk density range of 1.68'“1.90g/cm3. Their specific gravity ranged from 2.55-2.69. The soils have low natural moisture content, ranging from 1.61-8.00%. Atterberg limits of the fines showed that they are nonplastic to low plastic materials, with the highest PI as 12% (for the CL soil). The soils have low cohesion (0.66'“6.72kPa) but high frictional angle (32.54'“36.47o), except for the CL soil which has 27.31kPa cohesion and 19.34o friction angle.

From the findings, it was deduced that, generally, these soils are good backfilling materials, though to varying degrees (SW?GP?SP?SC?CL), because of differences in their engineering properties. However, factors that could alter their good characteristics and suitability were discussed and recommendations given.

Field Geology and Petrography of Granitoid rocks in southeastern part of Nanded district, Maharashtra State
This paper presents field geological and petrographic aspects of various granitoid units occurring around Khatgaon area in the southeastern part of Nanded district of Maharashtra. The study area is bestowed with granitoids of Archaean to Proterozoic age overlain by Deccan basalts of Cretaceous age. Three main types of granitoids were identified in the study area viz., older granites, gneissic/foliated granites and younger granites. These granitoid rocks are traversed by dykes, veins and veinlets of felsic and mafic composition. Although these granitoids are similar in mineralogy, they exhibit differences in petrographic characteristics.

The granitoids of the study area, especially the gneissic granitoids, comprise felsic and mafic lenticular enclaves of different sizes. Petrographically older and younger granitoids show medium to fine-grained, porphyritic and inequigranular textures. The gneissic rocks show foliation. At the contact of mafic enclaves and gneissic zones, conspicuous variation in mineralogy is observed in thin-sections. Presence of enclaves indicates coexistence and mixing of both felsic and mafic magmas at the source. The typical textures like perthitic, graphics and lamellar twinning indicate a direct magmatic origin for these granitoid rocks. The presence of pyrite mineralization at Khatgaon indicates late stage hydrothermal activity associated with felsic veins.

Source-Area Weathering, Composition and Paleo-Redox Condition of Stream Sediments from Ijero-Ekiti, Nigeria
Geochemical study of some stream sediments in Ijero-Ekiti was carried out to deduce their provenance, paleo-redox environment and source-area weathering. The SiO2/(Al2O3+K2O+Na2O) ratios for the paleoclimate during deposition indicates the arid/semi-arid conditions. This moderate climate will give rise to moderate weathering process. The weathering indices (CIA, CIW, PIA and MIA) and the A'“CN'“K Ternary diagram indicate a moderate degree of weathering of the source materials. The average Th/U ratio of the stream sediments is 1.66, which also suggests moderate degree of weathering of the source material. The stream sediments were enriched in both TiO2 and Zr, which implies that the stream sediments may have originated from a felsic source.

The bivariate plot of Na2O-K2O shows that all the samples are quartz-rich, which suggests that they may be of felsic origin. The provenance discriminant function plot shows the samples plotted mainly in the felsic igneous and quartzose sedimentary zones. The TiO2 versus Zr plot shows all the stream sediments plotting in felsic zone; average Cr/V ratio for sediments is 1.49, while the Y/Ni ratio is 0.98; suggesting a felsic source. Bivariate plots Ti versus Ni and K versus Rb revealed that the samples are of acidic/felsic intermediate composition. The ternary plot of La-Th-Sc of the analyzed samples suggest derivation from felsic rocks of granite and granodiorite composition. However, In the ternary diagram of V-Ni-Th*10, all the samples plotted in the mafic source area. Element ratios such as U/Th, Ni/Co, Cu/Zn, (Cu+Mo)/Zn, V/Cr and V/Sc indicate that the stream sediments were deposited under oxic conditions. V/(Ni+V) ratios indicate suboxic to anoxic environment of deposition while the Mn* values suggests oxic and suboxic environment.
