Evidence of an authigenic origin for palygorskite in a Middle Eocene carbonate sequence from North Qatar.
(
Qatar University
, 1997 , Article)
The "Simisma Member" from the Ras Laffan area in North Qatar is mainly composed of dolomites of shallow marine
origin. Clay minerals contained in the dolomite (average 4%) are mainly palygorskites. There is no indication ...
Pan African magmatism in the Zabara District, Central Eastern Desert, Egypt: Geochemistry and Petrogenesis
(
Qatar University
, 1997 , Article)
The rocks of the Zabara district include ophiolitic and non-ophiolitic sequences. The ophiolitic ones are metagabbro and metabasalt associated with metasediments, whereas the non -ophiolitic sequence includes intermediate ...
On the effectiveness of the vlf-em method For ground water prospecting in the Basement terrains, Sinai, Egypt
(
Qatar University
, 1997 , Article)
The VLF-EM method is proved to be an effective, fast and inexpensive tool for ground water prospecting in the basement terrains of Southern Sinai. The resistive shallow alluvial deposits increase the penetration depth of ...
Subsurface Exploration for Construction of Lightning Protection System Using the Geophysical Methods, Alexandria, Egypt (A Case Study)
(
Qatar University
, 1997 , Article)
Both electrical resitivity and total intensity magnetic measurements are combined together in an integrated manner to explore the subsurface layer and behavior of magnetic field in an area, where lightning protection ...
Study of carbonate rocks of the khuff and Jubaila formations , saudi arabia by Thermal derivatography
(
Qatar University
, 1997 , Article)
Thermal derivatographic analysis of the Khuff and Jubaila carbonate rocks shows that calcite and / or dolomite (of calcitic type) are the main constituent minerals. Their differential thermal and thermogravimetric behaviours ...
The role of radiogenic heat in maturation of organic matter within oil shales of Duwi formation in Quseir-Safaga District, Red Sea coastal area, Egypt
(
Qatar University
, 1997 , Article)
The oil shale beds of Duwi Formation at Quseir-Safaga district in Egypt show a high content of organic matter (kerogen) and a fair pyrolysis oil yield. Kerogens of these rocks are composed mainly of marine amorphous and ...
Geochemical studies using trace elements analysis of source rocks and related crude oil in the Gulf of Suez, Egypt
(
Qatar University
, 1997 , Article)
The occurrence and distribution of trace elements in source rocks and crude oils is used to asses the process of geochemical exploration. Rock and crude oil samples representing the giant fields of the Gulf os Suez province ...
Paleoecology, palynofacies, thermal maturation and hydrocarbon source-rock potential of the Jurassic-Lower Cretaceous sequence in the subsurface of the north Easern Desert, Egypt
(
Qatar University
, 1997 , Article)
The Jurassic to Lower Cretaceous sequences in the wells Abu Hammad-1, Q-71-IX and Kabrit-1, north Eastern Desert of Egypt, have yielded palynofacies assemblages of varying composition. Seven palynofacies types which are ...
