Crater formation during the onset of mud volcanism
Geology, 2023 AbstractThree-dimensional (3-D) seismic imaging was used to reveal >2.5-km-wide and >150-m-deep craters at the basal surface of 64 mud volcanoes out of a suite of 86, offshore Egypt. The craters were infilled soon after they formed by successive mud extrusions that combined to build mud volcanoes, as evidenced by onlap fill geometries of ...

Microspherules Formed by Lightning Strikes
Meteoritics &Planetary Science, EarlyView.Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Mud volcanoes and methane seeps in Romania: main features and gas flux
Annals of Geophysics, 2007 Romania is one of the European countries with the most vigorous natural seepage of methane, uprising from pressurised natural gas and petroleum reservoirs through deep faults. The largest seepage zone is represented by large mud volcanoes, with
