| Gold represents a country's economic strength, all countries attach great importanct to find it. Gold deposits in Southeast Guizhou are Widely distributed and mined for a long time,it is one of the major gold-producing area of Guizhou Province.But There is no uniform understanding on genetic types of gold deposits and it has not yet made a major breakthrough on mineral exploration. The study was limited to the macro structure and wall rock alteration and so on and there is the lack of more detailed study .This paper collects and collates the information on the basis of predecessors. With the geological survey in gubang and the observation of the samples of rocks and minerals from the mining area, this paper summarizes the geological background and features and study on the geological and ore mineralogy characteristics.It analyzes mineralization and prospecting on the exploration of gold deposit. The main results are as follows:(1) The structural condition of Gubang gold deposit is complex. The output of ore bodies are controlled by lithology and faults.Gold deposit in Gubang is mainly Altered rock-type and a small number of gold deposit is quartz vein-type.(2) The metallic minerals of Gubang gold deposit are mainly native gold, pyrite, chalcopyrite, magnetite, galena, sphalerite, chalcocite and Gangue minerals are mainly quartz, chlorite, feldspar,sericite.(3) The construction of Gubang gold deposit are mainly infection status, veinlets- stockwork,mottled-like, fragmentation-like. The structure of Gubang gold deposit are mainly euhedral, subhedral, anhedral, filling, replacement, crushed structure.(4) Shear zone is the direct sign of looking for altered rock,fracture zone in the Shear zone is the best goal of searching for ore bodies. |
