Baiyinchagan depression is part of downwarping faulted rift basin developed on XingmengHercynian multicycle and collision fold basement in late Mesozoic.
Submarine temperature, pressure, gas compositions, geothermal gradient and syngenetic water salinity control the depth of hydrate zone basement.Autochthonous bacteriogenic mod...
When the regional extension is disharmonic with the basement structure and movement, complicated fault assemblages can be form during progressive deformation.
The REE patterns for bitumen is similar to those for supracrustal sedimentary rocks in areas with no basement faults but stabilized structural settings.
Here PMN's that are marginated along the venule wall (arrow) are squeezing through the basement membrane (the process of diapedesis) and spilling out into extravascular space.
It is about 240m from surface of basement rock to the earths surface, Meilong rift crosses engineering site of Humin road viaduct ,which is not belong to mobile fit structure.
Minhe Basin is a Mesozoic-Cenozoic intermont basin grew on Precambrian metamorphic rock basement in middle Qilian uplift zone.Total thickness of Mesozoic-Cenozoic is about 7000 meters.
