Geochemistry and Petrogenesis of a Late Proterozoic Volcanic Sequence in the Magal Gebriel Area, South Eastern Desert, Egypt
(
Qatar University
, 2000 , Article)
Metabasalts and meta-andesites together with small amounts of metadacite constitute the Magal Gebriel volanic suite. Restricted amounts of unmetamorphosed rhyolitic rocks are also present. The metavolcanics show a wide ...
A study of contamination of the northern Jordan valley agricultural fields by various metal ions using regression analysis.
(
Qatar University
, 2000 , Article)
Geochemical analysis were performed in lower subsurface soil samples of 10,20,30 and 40cm depth, collected from seven regions in the northern Jordan valley. Eighteen descriptors (variables) for each sample were used. Among ...
Analysis of Gravity Measurements along Some Profiles On-Shore, Of Qatar Peninsula
(
Qatar University
, 2000 , Article)
A gravity study on the Qatar Peninsula was conducted to leam about density contrasts in this region and to gain information about subsurface geological structures favourable for oil and gas reserves. We recorded high quality ...
Tectonic Setting and Petrogenetic Evolution of Wadi Erier Rocks, South Eastern Desert, Egypt
(
Qatar University
, 2003 , Article)
A combination of geologic, petrographic and chemical criteria is used to classify the Erier basement rocks into three suites namely, the metagabbro-diorite (MGD) suite, the tonalite-granodiorite (TG) suite and the ...

(
Qatar University
, 2003 , Article)
Ferricretes of the Middle Eocene Dammam Formation, Western Qatar, were investigated using petrographic and ore microscopy, IR TGA, XRD, and geochemical analyses. The ferricretes mainly
consist of goethite, which is very ...
