Abstract The Algyő High (AH) is an elevated crystalline block in southeastern Hungary covered by thick Neogene sediments. Although productive hydrocarbon reservoirs are found these sequences, numerous fractured also occur the pre-Neogene basement of Pannonian Basin. Based on analogies, rock body AH might play a key role fluid storage and migration; however, its structure therefore reservoir pot...

Mashhad Metamorphic Complex (MMC) with metamorphic, granitic intrusions and ophiolite units is situated in the suture zone of Paleotethys in NE Iran. Triassic staurolite-garnet schist of Khalaj represents the highest grade of metamorphism in MMC. In this study EPMA analyses of garnet and biotite used to determine the maximum temperature for regional metamorphism. The pattern of zoning in garnet...

[1] Uppermost Cretaceous to Eocene marine sedimentary sequences occur both to the south and north of the Yarlung Zangbo suture in south central Tibet. They consist of Indian-margin strata of the northern Tethyan Himalaya and Asian-margin strata of the Gangdese forearc. Both assemblages are characterized by major changes in depositional environment and sedimentary provenance at 65 Ma and an appe...

Introduction: Individual grains and small lithic clasts in thin-sectioned suevitic breccia samples from the International Continental Scientific Drilling Program (ICDP) Bosumtwi impact crater drillcore LB07A were examined petrographically to evaluate the occurrence , abundance, and characteristics of unshocked and shock-metamorphosed quartz. The analyzed samples were taken across a ~42-m-long (...

The structural configuration of SW Japan mainly reflects a late Jurassic-early Cretaceous orogeny. The region is divided into an inner belt and an outer belt, on the Japan sea and Pacific ocean sides respectively, by a strike-slip fault, the Median Tectonic Line (MTL). Both consist of a series of stacked nappes. The inner belt is divided into a Jurassic olistostrome known as the Tanba zone and ...
