| 中文摘要: |
| 大华山金矿位于毛堂—蒲塘金矿田东南部,矿床由两种工业类型金矿组成,即产于岩体内的斑岩—隐爆角砾型金矿和产于岩体外构造破碎带中的构造蚀变岩型金矿。该矿区以构造蚀变岩型金矿为主,这种类型的金矿在毛堂—蒲塘金矿田尚属首例。文章对区域地质背景、矿区及矿床地质特征、成矿因素进行了分析,认为构造控制了岩体和矿体的空间分布,成矿物质来源于岩浆热液,金矿的形成与燕山期岩浆活动有密切关系。通过对毛堂—蒲塘一带地质特征的分析研究,并与大华山金矿进行对比,认为该地区具有较好的成矿地质条件,指出了矿区及外围找矿有利地段。 |
| 英文摘要: |
| The Dahuashan gold deposit is located in the southeast of the Maotang - Putang gold field. The ore can be divided into two types :porphyry-cryptoexplosion breccia type occurring in intrusive rocks and tectonic altered rock type occurring in the structurally fractured zone outside of intrusive rocks. The latter is the main type in this diggings. This kind of gold deposit was found for the first time in the Maotang - Putang gold field. Based on the regional geological background, deposit geological characteristics and metallogenic factors, the author integrates that the space distribution of rocks and ore bodies were controlled by structure; metallogenic material derived from magmatic hydrothermal fluid;the metallogeny of gold has a close relationship with Yanshan magmatic activities. The geological characteristics of Maotang - Putang area was studied and compared with the Dahuashan gold metallogenic characteristics. It has good ore-forming geological conditions in region and author point out the favorable area. |
