ANALYSIS ON THE GEOLOGICAL STRUCTURAL FACTORS LEADING TO THE DONGSHENGMIAO SUPER-LARGE DEPOSIT

Dongshengmiao super-large polymetallic sulfur deposit is genetically hydrothermal sedimentation type,occurred in the Langshan group which located in the western part of northern margin of north China platform and formed in the Langshan-Zhaertai Mesoproterozoic Aulacogen tectonic environment.The systematic studies show the major factors leading to the Dongshengmiao super-large ore deposit as follows:①the favorable regional geological structural setting;②the high abundance of ore-forming element in source bed;③ the excellent sealing ability and stability of mineralization environment;④the tectonic-thermal event in the sedimentary mineralization process;⑤the excellent conservation conditions.The regularities which are obtained in this study can provide some new informations and ideas for the study of the geological structural conditions of mineralization of(super) large ore deposits.
