new simplified tectonic models and depositional history of late cretaceous rocks are established in a part of zagros orogenic belt that is located in the northeastern iraq. these rocks constutes the most important cretaceous oil reservoir in the middle east. the dependent tools are petrography, field study and the concept of drowning phases. this concept is relatively new and accurate in explan...

Implementation of the underground storage of anthropogenic CO2 in geologic media requires containment of the CO2. The general concept for onshore, deep (> 800 m) geologic environments includes both a permeable reservoir and an overlying low permeability, high capillary-breakthrough-pressure “caprock”. Significant migration of the buoyant CO2 from the reservoir may lead to inadequate performance...

Introduction: The preponderance of 3.9 Ga lunar impact-melt rock ages and the dearth of older samples of unequivocal impact origin, from either the Apollo collection or lunar meteorites, suggest an extraordinary bombardment event in the Earth-Moon system at ~3.9 Ga. We have begun to study another set of samples, impact melts and crystalline lunar spherules (CLS) within demonstrably old Apollo b...

Quartz-rich sandstones in the Banda Arc Islands are thought to be equivalent of Mesozoic sandstones on the Australian NW Shelf where they are important proven and potential reservoirs. Previous studies suggested that rivers draining Australia provided most of the sediment input and there have been suggestions of a northern provenance for some Timor sediments. We present results from a provenanc...
