Desert roses are crystals which usually take the form of rose petal. They have definite crystal shapes, and enclose sand grains. The desert roses were scattered along an area of about 500m2 in the Ayn Dar area, near Abqaiq, ...

In order to evaluate the hydrogeological setting of the Quaternary aquifer and the related geological structures controlling its characteristics. A total of 50 vertical electrical soundings (VES.s) were conducted along 13 ...

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 ...

Photo-interpretation of landsat Thematic Mapper images of the Dukhan salt flats, on the west coast of Qatar, reveals several deposit zonations within the salt flats. The deposit zonations occupy a restricted sub-evaporite ...

Basic rock powders finder than 100 mesh were fushed in a molybdenum and tungsten boat in nitrogen atmosphere. The fusion technique uses very small amounts of sample which is suitable for rapid analysisof rock sample, ...

The Al-Shoaiba coastal lagoon located on the eastern side of the Red Sea is covered mostly with calcareous sand and muddy sand. Wind derived quartz is the most abundant detrital component in the surficial sediments of the ...

Dynamic forward modelling of carbonate diagenesis and sequence stratigraphy relies on the understanding of the different process which provide a high resolution prediction of the geometry of porous and permeable zones ...

Manganese oxides occurring at Wadi Dana (central Wadi Araba region, Jordan) are mainly hosted in the middle Cambrian dolomite limestone shale unit (DLSU). This deposit was investigated to elucidate their petrographic ...

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 ...

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 ...
