Abstract This study focused on joint interpretation of the aeromagnetic and radiometric data to allocate describe structural elements mineralization zones such as uranium, gold, sulfide in Gebel Umm Tineidba its surroundings, Eastern Desert, Egypt. The region is covered by exposures Precambrian rocks gneisses, migmatites, ophiolitic mélange, metavolcanics, younger granites, Quaternary sedimenta...

A 10 μm particle of cuprous gold was found in the phosphate-argillaceous matrix a three-layer Fe-Mn crust dredged from Guyot Alba Magellan Seamount (Pacific Ocean). The studied with scanning electron microscope at Institute Volcanology and Seismology, Far East Branch Russian Academy Sciences. is represented by an admixture platinum (up to 3.1 wt % Cu up 1.7 Pt). composition impurities suggests ...

Earth is the only known planet with subduction zones and plate tectonics, and this fact demonstrates that special conditions are required for this mode of planetary heat loss. Sinking of cold, dense lithosphere in subduction zones is the principal plate-driving force, so plate tectonics could not have begun until Earth cooled sufficiently to allow lithosphere to collapse into the underlying ast...

Abstract The so-called Triticoid-type grains are known from several prehistoric sites in southwest Asia and their identification has long been unclear. They resemble the of wheats researchers suggested they may represent an extinct Triticeae species, possibly closely related to wild crop progenitors. In this study we identify as Heteranthelium piliferum (Banks & Sol.) Hochst. describe key c...

The Eastern Anatolian Plateau (EAP), approximately 2000 m above sea level, is located between the Pontides to north, Arabian Platform south, and Iranian east. It characterized by 6 km-thick Maastrichtian Quaternary volcano-sedimentary cover which unconformably overlies continental oceanic basement units. Overall, outcrops of pre-Maastrichtian are rare include both This led drastically different...

Chromite is a strategic mineral resource for many countries, and chromite deposit occurrences are widespread in the ultramafic rocks of Yarlung Zangbo ophiolite belt, particularly harzburgite unit mantle section. Conducting field surveys complex poorly accessible terrain challenging, expensive, time-consuming. Remote sensing an advanced method achieving modern geological work powerful technical...
