On the basis of the geological charcteristics and field wok of us,we concluded indicator of Daxin gold deposite.

Daxin gold deposit is located on the edge of border zone of southern China geosyncline fold system and Yangtze para-platform and in the middle of Hunan lithosphere ancient subduction belt.

Developing cyclic economy and building green mines,the research and practice of environmental protection in Xincheng Gold Mine;

Xincheng gold mine belongs to the medium temperature hydrothermal filling metasomatic altered rock type.

Research and Realization on the Visualization Technology in Daxin Manganese Mine;

The paper first gives a brief introduction of how the people in Daxin Manganese Mine successfully accumulates manpower and wisdom in implementing a series of management systems based on humanity.

By adopting this software and based on the mine conditions and design data,a visualization system for Daxin Manganese Mine,CITIC DAMENG Mining Industries Limited was established.

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.
