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.

Liaojiaping dangerous rockmass is located on the left bank of the Changjiang River,with fractures developed,it threats the local residents and Changjiang sea-route badly.

Liaojiaping High-steep slope detailed exploration show that there are seven soft layer in the slope,there develops two teams joints,the two teams joints are high dips and vertical to one another,which forms many dangerous rockmass and rock columniation.

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.
