Provenance studies of Kalabsha kaolin deposits, Egypt: a petrographical and geochemical approach
The present study focuses on the kaolin deposit in Kalabsha area south Western Desert of Egypt in an attempt to determine itspossible source, tectonic setting, and weathering history by means of integrated petrographical and geochemical approaches. Thepetrographical studywas workedby microscopic investigationand supported by X-ray diffractionanalysis.X-rayfluorescence andinductively coupled plasma-mass spectrophotometry methods were used for the determination of the bulk elemental composition.Mineralogical ... إقراء المزيد

HISTORICAL BRICKS DETERIORATION AND RESTORATION FROM THERED MONASTERY, SOHAG, EGYPT: A GEOCHEMICAL, PETROLOGICALAND STATISTICAL APPROACHES
The present study investigates for the first time the historical bricks of The Red Monastery(west Sohag, Egypt), built about fifth century AD, which showing several aspects of brickdecay. Several techniques were employed (geochemical, petrographical, mineralogical andmorphological) to determine their deterioration features and provenance of the raw materialas well as shed lights on the firing techniques. In addition, integration of geochemical ... إقراء المزيد

Geochemistry and spatial distribution of selected heavy metals in surface soil of Sohag, Egypt: multivariate statistical and GIS approach
In this study, selected heavy metals were esti- mated in surface soil samples of Sohag, Egypt, with the aim to characterize their accumulation patterns. Median concentrations of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were 0.89, 39, 162, 74, 72,000, 1434, 72, 25 and 164 lg g -1 , respectively. The higher average concentra- tions of these ... إقراء المزيد

ЗНАЧЕНИЕ РАЗМЕРА ФРАКЦИОНИРОВАННЫХ ДОННЫХ ОСАДКОВ В РАСПРЕДЕЛЕНИИ ЗОЛОТА И СВЯЗАННЫХ С НИМ МИКРОЭЛЕМЕНТОВ ВАДИ ХАЙМУР ЮГО-ВОСТОЧНОГО ЕГИПТА
_Определение оптимального размера зерна фракции имеет важное значение для геохимического исследования донных осадков. В области Вади Хаймур Юго-Восточного Египта в засушливых областях с различными геологическими и геоморфологическими условиями было проведено геохимическое исследование ориентации донных осадков с целью оптимизации выбора размера зерна для распознавания минерализации. С использованием метода аква реджиа были исследованы четыре отобранных размера зерна фракций إقراء المزيد

IDENTIFICATION OF A GEOCHEMICAL SIGNATURE OF GOLD DEPOSITS IN STREAM SEDIMENT DATA: A MULTIVARIATE STATISTICAL APPROACH
In surficial geochemical exploration, scholars have often depend on simple statistical means or single-element concentration to investigate the relationship between elements in surface media and buried orebodies. In this study, a multivariate data analysis technique was used to explore the geochemistry of surfacestream sediments filling the main course of Wadi Haimur and its creeks. In this study, PCA analysiscombined with ... إقراء المزيد

MULTIDISCIPLINARY STREAM SEDIMENT GEOCHEMICAL EXPLORATION
The data gathering in systematic way, led to the construction of the first stream sediment geochemical maps of Wadi Haimur region, which is part of Wadi Allaqi protected area. In these maps, it is possible to find for each element a set of statistics (descriptive parameters, boxplots, cumulative frequency curves, etc.), maps of spatial distribution, among other information of geochemical ... إقراء المزيد

OUTLINE OF GOLD POTENTIAL OF THE WADI ALLAQI AREA IN SOUTHEASTERN DESERT, EGYPT
Gold occurrences in the Wadi Allaqi region of south-eastern Egyptwere reviewed in order to assess and paid the attention to their economic potentialand the broader potential of the geological environments in which they occur. Thestudy involved a review of all available published and unpublished references. Asgeneral case, the gold mineralization is confined to quartz veins forming depositsranging from 10,000 to ... إقراء المزيد

Геохимические исследования донных осадков по золоту и сопутствующим элементам в Вади Хаймур,  Юго-Восточной пустыни Египта
Геохимические исследование были проведены на высохших донных осадках площади Вади Хаймур Юго-Восточной пустыни Египта. Источниками этих отложений были, главным образом, подстилающие породы позднего протерозоя. Шестьдесят пять образцов донных осадков были исследованы на наличие 19 химических элементов в балке и четырех других различных фракций после горячего извлечения из царской водки. Простыми и многомерными статистическими методами были обработаны только результаты для балковой ... إقراء المزيد

GOLD DEPOSITS OF EGYPT AND FEATURES OF THEIR DISTRIBUTION
The gold deposits of Egypt are mostly in the Eastern Desert whichis hosted by Precambrian rocks. Within the Eastern Desert the gold mineralizationdisplays high clustering in the central and southern parts rather than the northern part.Eastern Desert of Egypt has been considered the main target for gold exploration andexploitation. The gold deposits can be divided into five groups based on ... إقراء المزيد
