10.basement and unmetamorphosed terrigenous shallow carbonate rock in the Austria Alps -South Alps obduc-tion nappe and radiolarian silicalite in fault basins.
The khondalite lithology is composed of a suit of metamorphic aluminium-sedimentary rock.During the Jinning movement, the sedmentary rock experienced four stages of metamorphism.
Some different metamorphic grade coals surface character was changed through the hypothermia thermal transnature in order to influnce the rheidity of coal-oil-water ternary material.
Research for geofluids is a hot-point and frontier in the geoscience field, especially, in igeous petrology, metamorphic petrology, geotectology and study of mineral deposits.
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.
They were exhumed upto the surface together with the Dabie complex after they were metamorphosed into eclogite at depth.During exhumation eclogite underwent different degrees of retrometamorphism.
The former three stages reflect the major process of eclogite facies metamorphism and the latest stages the light overprinting of greenschist facies retrometamorphism at the shallow level of crust.
