治岭头金银矿床是近年来在浙江探明的一个大型矿床.本文试图通过硫同位素的研究成果,结合矿床地质特点,就成矿物质来源及矿床成因进行初步探讨,祈能有助于矿床研究和普查找矿工作. 地质概况矿区位于陈蔡-遂昌加里东隆起带西北缘之大柘断块隆起向东延伸的转折部位.其南北两侧各以丽水-余姚及江山-绍兴深断裂分别与东南沿海华力西地槽褶皱带及钱塘加里东冒地槽相毗邻. 矿区地层分为两部分.前奥陶系陈蔡群(K-Ar等时年龄为381.5及491.8百万年)构成褶皱基底,上侏罗统磨石山组为盖层.前者为一套以黑云斜长片麻岩类为主,间夹变粒岩、浅粒岩、长英质岩等的中深变质岩系,原岩为砂岩、泥质
Zhilingtou gold-silver deposit is a large proven mineral deposit in Zhejiang Province in recent years.This paper tries to discuss the origin of metallogenic materials and the genesis of the ore deposit by combining the research results of sulfur isotopes and the geological features of the deposit, Research and prospecting Geological Overview The mine is located at the turning point of the uplift to the east of the Dajian block in the northwestern margin of the Chencai-Suichang Caledonian uplift, with the Lishui-Yuyao and Jiangshan-Shaoxing deep faults Respectively, and the southeastern margin of the Harisi Gully Fold Belt and the Qiantang Caledonian trough adjacent to the mining area strata are divided into two parts of the former Ordovician Chen Caiqun (K-Ar equivalent age of 381.5 and 491.8 million years) Forming the fold basement, and the upper Jurassic Mount Shishan Formation is the caprock.The former is a set of middle-deep metamorphic rocks dominated by biotite plagiogranites, intercalated granulites, shallow gravels and feldspathic rocks Rock, the original rock sandstone, muddy
