【 摘 要 】

The Dongchuan area in China is part of the Sichuan-Yunnan-Guizhou polymetallic metallogenic field and contains extensive ore-deposits. Although gold was first discovered in the area in the 1990s, gold exploration and research are currently limited; only five areas have currently been identified as containing gold deposits with reserves of more than 20 tons. However, the area is believed to have considerable prospecting potential. Gold deposits mainly occurring in the wall of the rock mass have been found in the upper-middle section of the Pingdingshan Group to the lower-bottom section of the Yinming Group in relation to the intrusive action and development of sodium diorite. It has been determined that the core of the anticline complex and its nearby fault zone are the major ore hosting structures and that gold-deposit prospecting should be conducted around the N-S compressive shear zone. In this study, sites are determined that have certain characteristics accompanied by a high degree of rock formation and complete assemblages of lithological composition; these are considered to be locations conducive to the prospecting of gold deposits.
