Abstract The classical concept of collisional orogens suggests that mountain belts form as a crustal wedge between the downgoing and overriding plates. However, this orogenic style is not compatible with presence (ultra-)high pressure mantle rocks far from plate interface in Bohemian Massif Central Europe. Here we use comparison geological observations thermo-mechanical numerical models to expl...

This study focuses on seafloor methane seep sites and their distribution in the northwestern part of German North Sea. Methane seepage is a common phenomenon along marine shelves known to occur Sea, but proof existence was lacking area. Using ship-based multibeam echosounder we detected minimum 166 flares that are indicative for free gas releases from “Entenschnabel” area, which not related mor...

In paper based on the results of previous studies and latest investigations of mud volcanoes in the South Caspian basin the depth occurrence of fluid, mud and rocks are calculated and modeled. Major factors causing formation of diapirism/mud volcanism in the South Caspian basin are Pliocene-Quaternary high sedimentation rates (up to 3 km/my), super thick sedimentary cover (up to 25 30 km), pred...

THE Costa Rican forearc is characterized by active fluid venting related to mud diapirism and volcanism. The geochemical compositions of fluids obtained from dewatering sites indicate that mineral precipitation or dehydration is the major driver of fluid mobilization and upward migration. The peculiar situation at the latter sites is that Ca concentrations in the upward migrating fluids are wel...

Exhumation has been recognized as an important problem in tectonics and can be achieved by normal faulting, ductile thinning, and erosion. The exhumation of ultrahigh-pressure (UHP) rocks is the most challenging and least understood aspect of the exhumation problem. In this review, we focus on a variety of geologic settings with the goal of characterizing exhumation rates and maximum depths of ...

Geomorphic features (fossil terraces, notches and sea cliffs) from the southern Red Sea coasts provide valuable indicators of past sea-level change that enable quantification both timing magnitude mid-Holocene highstand. We demonstrate utility wave-cut in Sea, present U-series dated two locations on As-Salif Peninsula suggest a highstand ?0.5–1 m above mean level (apmsl) at about 5–5.4 ka BP. I...
