The 3.43 billion-year-old Strelley Pool Chert, Pilbara Craton, Western Australia, contains compelling evidence of Early Archaean life in the form of kilometre-sized remnants of an ancient stromatolitic carbonate platform. Reviewing and building on earlier studies, we examine the fossilized remains of the platform to seek ecosystem-scale insights to Earth’s early biosphere, examining the evidenc...

The southwestern margin of the South China Craton preserves a Late Permian to Early Triassic sedimentary succession, provenance which helps constrain magmatic history and tectonic evolution Paleo-Tethyan Orogen. In this study, we present new detrital zircon U-Pb age, trace element, Hf isotope whole-rock geochemical composition analyses from Lower Qingtianbao Formation, distinguish clastic rocks...

A nuclear magnetic resonance (NMR) logging tool can provide important rock and fluid properties that are necessary for a reliable reservoir evaluation. Pore size distribution based on T2 relaxation time resulting permeability among those parameters cannot be provided by conventional tools. For wells drilled before the 1990s many recent there is no NMR data available due to availability cost, re...

The formation of oxalates in soils and rocks under conditions cryoarid climate, permafrost taiga vegetation was studied. Whewellite weddellite were found four areas associated with the mining industry: on kimberlite deposit Daldyn territory, lower reaches Markha River Central Yakut Plain, coastal outcrop Allah-Yun Sellah-Khotun ore cluster. upper organic horizon Skeletic Cryosol (Thixotropic) (...

The salt-rich Orpheus rift basin, part of the eastern North American (ENAM) system, formed during Late Triassic to Early Jurassic prior opening Atlantic Ocean. Using a dense grid 2D seismic-reflection lines, data from nearby wells, and information adjacent ENAM basins, we have established tectonostratigraphic framework, identified key structural elements, reconstructed deformation history for b...

The Cretaceous deposits in Morakan, located in the northeast of Khoy, a town in western Azerbaijan province, Iran, are primarily made up of carbonate rocks. These deposits, which are of 717 meters thick, lie on the clastic facies of Jurassic and are covered with beneath the pelagic beds of the Upper Cretaceous. To investigate the facies, sedimentary environment and sequential stratigraphy of th...
