Sediments of the Nezam-Abad area, south-east of Bam have been studied for the first time. Sedimentary facies are composed of thin-bedded clay, silt and fine grained sand interbedded with thin laminated limestone. Chemical analysis of X-Ray florescent indicates that more than 50% of sediments consist of silisium and aluminum oxide that can be used for reconstruction of environment. Ninety eight ...

Laguna Mar Chiquita (central Argentina; ~latitude 31°S, longitude 63°W) provides an outstanding opportunity to examine organic facies development and petroleum source-rock potential in a modern thick-skinned foreland basin lake. In this case study, we defi ne profundal, paleodelta, and lake-margin depositional environments based on trends in bathymetry and lake-fl oor sediment particle size. Se...

Tidal sandstone reservoirs contain significant intervals of hydrocarbonbearing heterolithic facies, characterized by the presence of tidegenerated sedimentary structures such as flaser, wavy, and lenticular bedding (millimeter to centimeter sand-mud alternations). We have characterized the reservoir properties (sandstone connectivity, effective permeability, and displacement efficiency) of thes...

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...
