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...

Abstract. The dynamics of growing collisional orogens are mainly controlled by buoyancy and shear forces. However, the relative importance these forces, their temporal evolution impact on tectonic style orogenic wedges remain elusive. Here, we quantify forces during orogeny investigate wedge formation exhumation crustal rocks. We leverage two-dimensional petrological–thermomechanical numerical ...

Gas hydrates have been considered as a new energy that could replace conventional fossil resources in the future because of their high density, environmental friendliness, and enormous reserves. To further analyze potential distribution gas hydrate stability zones (GHSZ) formation system Shenhu area South China Sea (SCS), 3D petroleum simulation model (PSM) was built from seismic interpretation...

The Tommeliten seepage area is part of the Greater Ekofisk area, which is situated above the Tommeliten Delta salt diapir in the central North Sea (5629.90 N, 259.80 E, Norwegian Block 1/9, 75 m water depth). Here, cracks in a buried marl horizon allow methane to migrate into overlying clay-silt and sandy sediments. Hydroacoustic sediment echosounding showed several venting spots coinciding wit...

Detailed geological analysis of the Lakshmi Planum region of western Ishtar Terra results in the establishment of the sequence of major events during the formation and evolution of western Ishtar Terra, an important and somewhat unique area on Venus characterized by a raised volcanic plateau surrounded by distinctive folded mountain belts, such as Maxwell Montes. These mapping results and the s...

Abstract The mantle–crust boundary beneath oceanic spreading centres is a major chemical and thermal interface on Earth. Observations in ophiolites reveal that it underlined by dunitic transition zone (DTZ) can reach few hundred meters thickness host abundant chromitite ore bodies. dunites have been deciphered as essentially mantle-derived most ophiolitic massifs; is, reactional residues of int...

Albedo, spectral slopes, and water ice band depths maps for the five midsized saturnian satellites Mimas, Enceladus, Tethys, Dione, Rhea have been derived from Cassini-Visual Infrared Mapping Spectrometer (VIMS) data. The are systematically built photometric corrected data by applying Kaasalainen-Shkuratov model (Kaasalainen et al., 2001; Shkuratov 2011). In this work a quadratic function is us...
