Golden minerals in Carlin-type gold ore are dominated by native gold and argentiferous native gold of Au-Ag series, havehigh fineness,and are mainly enriched insulfide facies.
The sedimentary facies in Heshilafu is an alluvial fan - fan delta -lake systetn, and it can be further devided into several parfacies including microfacies.
After rapid overall swelling , in the late stage occurred alluvial fan-braided river facies sedimentary cycles made of red polyterrigenous molasse deposit s with multi-source supplying.
Dissolution is controlled by both sedimentation and tectonization, and the converted degree on reservoirs is closely related to sedimentary facies and the distance from unconformity interfaces.
To date, komatiites with spinifex textures have not been found in the supracrustal rocks, but rock sequences similar to greenstones metamorphosed up to upper amphibolite facies are often observed.
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.
Site soils in southern area of Jiangsu province belong to washland sediment or limnetic facies sediment.The components of sediment are very complex and process of sedimentation is in disorder.
Its original rock is sedimented in the environment of active epicontinent-seaboard with basic volcanism, and become khondalite series through the Archean regional high-amphibolite facies metamorphism.
