天井金矿是民采老矿,局部地段民采已深达30—40米,60—70年代湖南省区测队,武警黄金15支队,曾先后在此矿山进行过地质研究工作。我队于1987年2月,上山进行了钻、硐探揭露工作,写有地质报告,并取得了一定储量。 本文是在这次揭露工作取得资料基础上,试图总结矿床地质矿化规律,并着重探讨其氧化带成矿问题。关于氧化带成矿问题,一些文章已有涉及,但作为金矿工业类型来研究的文章还少见。在找矿生产方面,由于上述成因的一些金矿床,尤其是含硫化物石英脉金矿床,地表矿化极富,而地下骤然变贫的现象,曾给找矿、评价工作带来一定的困难,因此对这个问题的研究,不仅是一个新类型的理论问题,而且更是指导金矿找矿和评价
The mine is a mining old mine, local mining has been as deep as 30-40 meters, 60-70 years of the Hunan Provincial Area Police Team, Armed Police Corps of Gold 15, has conducted in this mine geological research work. My team in February 1987, went up the mountain drill, cave exploration exposed work, wrote a geological report, and made some reserves. Based on the data obtained from this work, this article attempts to summarize the law of mineralization of the ore deposit and focus on its oxidization zone mineralization. Some articles have been dealt with on the issue of oxidized belt mineralization, but articles that are studied as gold mine industrial types are still rare. In prospecting production, due to the above-mentioned causes, some gold deposits, especially the sulfide-bearing quartz vein gold deposit, are extremely rich in surface mineralization and the phenomenon of sudden subsidence in the underground has brought some difficulties in prospecting and evaluation Therefore, the research on this issue is not only a new type of theoretical issue, but also guides the gold prospecting and evaluation
