Concentration of platinum group elements(PGE) of various gold ores and around rocks and Re-Os isotopic compositions of major ore minerals of Daping gold deposit were analyzed by using an inductively coupled plasma mass spectrometry(ICP-MS) with nickel sulfide fire assay pre-concentration and carius tube decomposing technique with acetone extracted Re method.

Mineralization epochs of the Daping gold deposits are divided into three stages:the early stage or scheelite-bearing quartz vein stage,the major stage or massive polymetallic sulphide typed auriferous quartz vein stage and the late stage or carbonate-quartz stage.

The application of filling technique of filling-mining method in Dongping Gold Mine;

The faults of various times coincided with,and rebuilded by the ore-formation in the later mineralizing process,and became the ore-occurrence structures of the Dongping gold deposit.

4 Ma, showing a significant time gap as compared with the ore-forming age of the spatially closely related Dongping gold deposit.

The natural gold from Dongping gold deposit is various in morphological characteristic,mainly in form of inclusion gold and fissure gold with large grain size (0.

Through analyzing regional geological setting and geological characteristics in Jinjiaping manganese deposit,it is supposed that the formation of manganese deposit in this area is divided into such 4 stages as continental facies,marine facies,solidification-dehydration-crystallization of ore-forming materials,the deposit is classified into marine sedimentation-sub-recomposed deposit.
