摘要
Based on systematic analysis of lithological composition, microstructure and sedimentary facies, in this paper many discusses have been conducted for the REE characteristics of Longeni-Angdanreo paleo-oil dolomite in southern part of the central uplift zone of Qiangtang Basin. The results show that REE have been undergoing an impoverished process in dolomitization, and the calcite has been formed in deep water deoxidized environment, the dolomite being formed in shallow water oxidized environment.
