Abstract:

In order to strengthen the Quxi gold deposit prospecting work in east Hunan Province,we used methods of directions geological survey,structual mapping,deposit(dot) investigation,petrology-geochemistry and remote sensing interpretation to study geological features and ore-controlling factors of the area,and we summarized metallogenic regularity and prospecting of Quxi gold mine,finally established ore-controlling model.Based on the research above,we reach some conlusion as follow:the gold-bearing rock is Lengjiaxi Group which is made of weakly metamorphic siltstone.NNE trending deep faults in the area are thermal conductivity and mineralization channel,the smaller secondary fracture of it and deep fault towards angle which was the rupture of better ore in mining area.Yanshanian monzonitic granites provide some mineral sources for mineralization in Quxi gold deposit.According to the ore-forming regularity and prospecting indicators,three potential targets such as Shaguoli,Jidongkeng and the depth of No.1 lode have been determined in deep mining area and its periphery.By our field survey and research,we think the Shaguoli previous regarded as a gold-antimony deposit,but it is a gold-tungsten deposit.The work and results supply us with next step prospecting ideas in this area.

Key words: Ore-controlling factor, Ore-forming regularity, Metallogenic prognosis, Quxi gold deposit, Hunan Province
