Abstract:

 Current studies on oil-gas geology in Qiangtang Basin mostly focused on Jurassic strata, and only a few researches about the Paleozoic. Based on the data of thin section analysis, x-ray diffraction, cathodeluminescence, element geochemistry and C-O isotope, this paper studied the petrological and geochemical characteristics of dolomite of Zhanjin Formation in Qiangzi 5 well in Jiaomuchaka area, and discussed its genesis. The result shows that fine crystalline dolomite and crystal powder dolomite mainly developed in tidal flats of limited carbonate platform. They are characterized by cloudy centers and clear rims, clitellum and residual-grain, and the metasomatism is obvious. They are characterized by low-middle δ13C positive value （2.7‰～4.4‰）, low-high δ18O negative value （-8.4‰～-2.8‰）. Most diagenetic temperature are below 44℃, which indicates that the temperature degree of dolomitization is low. Salinity ranges from 20.98‰ to 30.16‰, below the salinity of sea. The middle value of the order degree of dolomite, together with the low content of Mg/Ca, Fe, Mn, Sr, and REE distribution pattern reveal a characteristic of burialdolomitization. All evidences indicate that the dolomite of Zhanjin Formation mainly formed in an early shallow burial environment with low temperature, and there may be a fresh water injection during the diagenetic process.
