Abstract Exhumation of basement rocks on the seafloor is a worldwide feature along passive continental margins and (ultra-) slow-spreading environments, documented by dredging, drilling or direct observations diving expeditions. Complementary from exhumed ophiolites in Alps allow for better understanding underlying processes. The Aiguilles Rouges ophiolitic units (Val d’Hérens, Switzerland) are...

Undoubtedly, involving more tools, datasets, and techniques for detecting the mineralized areas sharply narrow zones to be investigated delivered, in most cases highly potential zones. Consequently, this study is an attempt apply remote sensing data including Sentinel 2 ASTER, field observations, petrography of hydrothermal alteration processes, ore microscopic investigations, X-ray examination...

Numerical analysis of geophysical data to uncover Precambrian belts and probably enclose mineral deposits is becoming once more communal in mining activity. The method founded on typifying zones branded comprehend looking for analogous areas. proposed work outlines a semi-automatic image processing system the structural investigation Bou Azzer inlier, which varies from preceding approaches as i...

A net of pegmatite veins crosscut gneiss and dismembered ophiolitic ultramafic rocks are abundant in the Migif-Hafafit culmination area, South Eastern Desert, Egypt. Some these pegmatites corundum-bearing. Corundum-bearing studied eight localities around complex. The present study aims to integrate field investigation, whole rock corundum chemistry, remote sensing studies, conventional methods ...
