Sources and behavior of trace elements in groundwater in the South Eastern Desert, Egypt
Due to water scarcity, the groundwater will represent an essential source of water in many communities worldwide. This study was carried out to investigate the main hydrogeochemical characteristic of trace elements composition, their sources, and its vulnerability in groundwater to the human population. Fifteen groundwater samples were collected from boreholes and hand dug wells from the South Eastern Desert, Egypt, ... إقراء المزيد

Geochemistry, petrogenesis and radioactivity of Pan-African granitoids, Fatirah area, Eastern Desert, Egypt.

Geochemistry, petrogenesis and radioactivity of Pan-African granitoids, Fatirah area, Eastern Desert, Egypt.
On the basis of the geological and petrological investigations, the Pan-African granitoid rocks of Wadi Fatirah area are differentiated into two distinct assemblages, viz. the older granites and younger granites. The older granitoids comprise quartz diorite, tonalite and granodiorite, arranged in accordance to their sequence of emplacement. The older granites are calc-alkaline in character and of I-type and were emplaced ... إقراء المزيد

Petrology, geochemistry and opaques of mélange rocks along Wadi Abu Haramiya, Central Eastern Desert, Egypt.

Petrology, geochemistry and opaques of mélange rocks along Wadi Abu Haramiya, Central Eastern Desert, Egypt.
The Precambrian basement rocks exposed along Qift- Quseir asphaltic road, central Eastern Desert (CED) of Egypt, exhibits two contrasted tectonic units each of which has its own lithology structural style and grade of metamorphism. The older (lower infrastructural rocks) unit exposed in the Meatiq swell is composed of mylonites, cataclased gneisses, amphibolites and gneissose granite and is intruded by syn-to ... إقراء المزيد

Geochemistry, petrogenesis and fluid inclusion studies of the Kadabora granite pluton and associated enclaves, Central Eastern Desert, Egypt.
_The studied area is occupied by Neoproterozoic basement rocks comprising ophiolitic melange, metagabbro-diorite complex, younger granites and post-granite dykes._ _Detailed field studies revealed that Kadabora pluton is differentiated into three phases: granodiorite phase I, monzogranite phase II is and finally syeno- alkali feldspar- granite phase III._ _Mafic enclaves (ME) with andesitic composition are recorded only in granodiorite phase I and ... إقراء المزيد

Continental Rift Zone (CRZ) Al-Haruj Tertiary basalts, Libya: Petrological and geochemical approach.

2018-10-03 07:45:31 الكلمات المفتاحية Continental Rift, Geochemistry, Basalts, Libya, Al Haruj,
Continental Rift Zone (CRZ) Al-Haruj Tertiary basalts, Libya: Petrological and geochemical approach.
Al-Haruj Tertiary basalts cover an area of about 50,000 km2 in central Libya. This occurrence is the largest among the other Libyan occurrences. They are diferentiated in the field into two volcanic series separated by a long hiatus. Each series is characterized by its weathering features, morphology and primary igneous structures. Geochemically, Al-Haruj basalts are alkaline to subalkaline, suggesting increasing ... إقراء المزيد

Petrological and geochemical investigations of Dokhan volcanics in Wadi Sodmein area, Central Eastern desert, Egypt.

2018-10-03 08:18:18 الكلمات المفتاحية Sodmein, Dokhan volcanics, , Eastern Desert, Egypt, , Geochemistry,
Petrological and geochemical investigations of Dokhan volcanics in Wadi Sodmein area, Central Eastern desert, Egypt.
Wadi Sodmein area lies to the northwest of Quseir town on the Red Sea. The studied volcanic rocks are distinguished into Dokhan Volcanics and felsites. The Dokhan Volcanics are subdivided into two rock units, an older unit of andesite-dacite composition and a younger unit of rhyolite, rhyolitic tuffs and ignimbrite. They have petrographical and geochemical features similar to calc-alkaline, subduction-related ... إقراء المزيد

Application of Mineral Liberation Analysis in studying micro-sedimentological structures within sulfide mine tailings and their effect on hardpan formation

Application of Mineral Liberation Analysis in studying micro-sedimentological structures within sulfide mine tailings and their effect on hardpan formation
In this paper, mineral liberation analysis (MLA) was applied as a new approach to elucidate and quantify textural, mineralogical, and chemical variations on a μm/mm scale to understand the alteration processes relevant for hardpan formation at the Davidschacht mine tailings in Freiberg, Germany. Additionally, the bulk mineralogical, geochemical, and physical properties were investigated in detail. Within the upper 1.5m of ... إقراء المزيد
