《"A Model of Hydrothermal Dolomite Reservoir Facies in Precambrian Dolomite, Central Sichuan Basin, SW China and its Geochemical Characteristics"》
Generally,the concentration of trace elements in sedimentary fluid and diagenetic fluid is the main factor contributing to the trace elements enrichment in rocks.As previous reports,the diagenetic fluid that affected the micritic dolomite in the Dengying Formation is normal or evaporated seawater.On the contrary,formation of saddle dolomite is attributed to the hydrothermal fluid which comes from deep-burial storage.This difference is directly reflected in the Fe and Mn concentrations of the two different fabrics dolomite mentioned above(Fig.7a)(Table 1) .
