The sedimentary facies in Heshilafu is an alluvial fan - fan delta -lake systetn, and it can be further devided into several parfacies including microfacies.
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.
Cuspate deltaic sands micro-facies, which formed at the time of powerful wave action, the continuity of marine distributary channel is bad, and distributes in cuspate shape. 3.
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.
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.
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.
The author suggests that the Zhiluo Formation belongs to the typical fluvial sedimentary facies, which cab be further refined to the channel, flood-plain and backswamp 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.
