Sedimentary Rocks composing the Thar Lignite basin Pakistan are of clastic origin. These rocks have comparatively low uniaxial compressive strength (UCS) values, and hence recognized as ‘soft sedimentary rocks’ in this study. UCS is a fundamental property rocks, used by mine design engineers designing surface underground excavations. The purpose study to investigate relationship between with Br...

Abstract As more engineering projects and activities are taking place on around weak rocks, it is becoming important to study characterize them. Since regular practices of rock mechanical testing not effective for special laboratory tests measurements were performed the Alkharj Saudi sandstone which a clastic dominantly sandy limestone sandstone. Test results presented in this paper. Porosity, ...

Abstract The Zagros orogen, formed by the collision of Arabian and Eurasian continental margins, represents one largest richest oil gas provinces in world. fold-thrust belt records convergence along Neotethys suture zone. By coupling field observations, sandstone modal analysis, U-Pb zircon dating, Hf isotopic data from Upper Cretaceous to Pliocene sedimentary succession Neyriz region, this pap...

Integrated organic petrographic and geochemical analyses were made on organic-rich marine carbonate mixed clastic-carbonate rocks of Middle–Late Jurassic Early Cretaceous age from the Shushan Basin, Egypt to evaluate their hydrocarbon potential. Analyses allowed identification depositional settings, paleoclimate, three third order genetic stratigraphic sequences (SQ) with deposits assigned high...

3D geological modeling of lithogeochemical and geological data provides insight into the role of the sulfide ore horizon and associated footwall hydrothermal alteration in localizing shear strain in the Flin Flon volcanogenic massive sulfide deposits, Canada, as deformation evolved from brittle-ductile to ductile regimes during collisional stages of the 1.9–1.8 Ga Trans-Hudson orogeny. 3D spati...

The central part of the Fennoscandian Shield in Finland is composed of the Palaeoproterozoic Svecofennian domain and the Archaean Karelian craton with a Palaeoproterozoic allochthonous and autochthonous cover. A cryptic suture separating these areas and another tentative suture dividing the Svecofennian into central and southern parts have been proposed. The chemical composition of sedimentary ...

The Blue Nile Basin, situated in the Northwestern Ethiopian Plateau, contains 1400 m thick Mesozoic sedimentary section underlain by Neoproterozoic basement rocks and overlain by Early–Late Oligocene and Quaternary volcanic rocks. This study outlines the stratigraphic and structural evolution of the Blue Nile Basin based on field and remote sensing studies along the Gorge of the Nile. The Blue ...
