Baiyinchagan depression is part of downwarping faulted rift basin developed on XingmengHercynian multicycle and collision fold basement in late Mesozoic.
Planar strips,vertical stages,continuous backpedal and strong succession are the characteristics of the glutinite body distribution in a rift extensional basin.
Ankerite microclinite, a special type of rock, is closely related to the ore-forming process of massive sulfide deposits in the East Liaoning Proterozoic rift.
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.
