摘要
安徽省进行金刚石找矿工作已有逾50年历史,做了大量的勘查、科研工作。从20世纪60年代开始,找矿队伍前后有6个地勘单位,最后于1975年稳定于原安徽省地矿局664地质队。找矿区域涉及皖南山区、大别山区、江淮之间及淮河以北广大地区,但主要集中在淮北地区。找矿历程经历了起步阶段、全面展开阶段、停滞阶段、恢复阶段及新一轮的金刚石找矿阶段。在全面展开阶段发现了震旦系金山寨组底砾岩含金刚石和第四系中下更新统豆冲组、潘集组砂砾层中金刚石砂矿点。在新一轮金刚石找矿中分别发现了玄武质角砾熔岩、辉绿岩和橄榄玄武岩中含原生金刚石。目前,安徽省的金刚石找矿勘查、科研工作仍在进行中,正在向原生金刚石矿床冲击。
With a history of over 50 years, diamond exploration in Anhui Province has done a great deal of work in survey and scientific research. Since 1950s, there have been a total of 6 exploration units working on diamond survey and they finally reduced to only one unit No.664 focusing in diamond survey in 1975. Regionally, the diamond exploration has covered the south Anhui mountainous area, the Dabie mountainous area, the area between the Yangtze River and Huai River, and the broad area north of the Huai River. It experienced the starting, overall expanding, stopping, recovering and the latest round of exploration stages. At the overall expanding stage, diamond was found in the basal conglomerate of the Sinian Jinshanzhai Formation, in the mid-lower Pleistocene Douchong Formation, and in the placer in sandy gravel bed of Panji Formation of the Quaternary. Laterly, diamond was discovered in basalty brecciated lava, diabase and olivine basalt respectively. Presently, diamond exploration work is going on rapidly toward finding a primary ore deposit.
