Delay in making presidential appointments harms research and the broader public.
Large sublacustrine fan deposits have been identified within the lacustrine successions of the second member of the Palaeogene Dongying Formation in the Liaozhong Depression. In this study, by using comprehensive and detailed analyses of the borehole lithology, limited cores, wireline logs, and seismic facies, 4 types of sublacustrine fan deposits were identified and characterized. Then, an integrated depositional model was established based on the above investigations. The result indicates that the geophysical characteristics of the different sublacustrine fan deposits differed from each other, in terms of their internal configuration and external geometry of seismic reflections, and stacking patterns of wireline logs, and stratigraphic position in the vertical successions. Subsequently, the model was established according to the comprehensive analysis of the geophysical characteristics and stratigraphic position. The discussion of developing conditions and hydrocarbon discoveries within different types of sublacustrine fan deposits provided robust insights regarding how to locate and evaluate reservoirs in such deposits. Furthermore, the results of this study may potentially assist in achieving a new understanding of how to identify sublacustrine fan deposits in similar lacustrine basins and may also assist in making further decisions regarding the terms of hydrocarbon migration and accumulation.
Brown University researchers have published the most detailed geological history to date for a region of Mars known as Northeast Syrtis Major, a spot high on NASA’s list of potential landing sites for its next Mars rover to be launched…
Researchers have developed a method to measure one of the most striking and difficult to measure volcanic features – volcanic lightning – using the tiny glass spheres formed by hot volcanic ash.

A new study is challenging a long-held theory that tsunamis form and acquire their energy mostly from vertical movement of the seafloor. The finding validates an approach developed by researchers that uses GPS technology to detect a tsunami’s size and strength for early warnings.
Major investment in regenerative medicine enters its last stage — and the money might run out before treatments are ready.
DGIST research team led by Professor CheolGi Kim has developed a biosensor platform which has 20 times faster detection capability than the existing biosensors using magnetic patterns resembling a spider web….
