Abstract

Abstract

The Upper Sinian-Lower Paleozoic dolostones is widely developed in the Yangtze platform, which is one of the most important carbonate reservoirs. There has been few studies on the dolostone in the Lower Yangtze region, restraining our recognition to the properties of dolostone reservoir. In this paper it systematically investigates the geochemical characteristics and formation mechanisms of dolostone in the Lower Yangtze area based on an integrated petrological, major and trace element, rare earth element, and carbon oxygen isotope analyses. The results show that the studied dolostone can be divided into four types, namely, micrite dolostone, powder-fine dolostone, fine crystal dolostone, and medium crystal dolostone. The Upper Sinian micritic dolostone has high Mg content and low Fe, Mn, Sr contents, high δ¹⁸O value, forming temperature close to surface temperature, higher salinity index compared with sea water, low ΣREE value, negative Ce and Eu anomalies, and REE distribution pattern which are similar to marine limestone, indicating the dolostone belongs to penecontemporaneous dolomitization in an environment of concentrated seawater fluid with strong evaporation near the surface. The Middle Cambrian powder-fine dolostone is characterized by fog-core bright edge structure, similar contents of Mg, Fe, Mn and REE characteristics compared with micritic dolomite, high salinity index, and relatively medium δ¹⁸O value ranging from -2.5‰ to -6.5‰. The genesis of this dolomite is percolation reflux dolomitization in shallow burial environment. Marked by higher Fe content and ∑REE values, low δ¹⁸O value (-6.5‰ to -10‰), higher formation temperature, the Upper Cambrian fine-grained dolostone is attributed to buried dolomitization genetic. The Lower Ordovician medium crystal dolomite is characterized by high contents of Fe, Mn, Al, Si, Sr and ∑REE value, low δ¹⁸O value less than -10‰, lower salinity index compared with sea water, positive Eu anomaly, and high diagenetic temperature with thermal alteration characteristics, suggesting the dolomite is of hydrothermal dolomitization origin.
