| 摘 要： | 黄山箬岭金矿区位于扬子陆块江南古陆东段,处于下扬子成矿省(Ⅱ-11)江南地块中生代铜-钼-金-银-铅-锌成矿带(Ⅲ-53)内。通过矿产勘查工作,认为箬岭地区具有较好的金矿成矿地质条件,目前已发现多条金矿(化)带,含金品位达1.27×10-6~8.52×10-6。在对成矿地质条件、矿床地质特征分析的基础上,总结了区域上寻找该类金矿的找矿标志,认识到矿区NW向与NE向断裂构造交汇部位是金、银矿化富集的有利部位,矿区内与金矿化密切相关的围岩蚀变是硅化、黄铁矿化、褐铁矿化,矿石类型主要有构造蚀变岩型和石英脉型。

Geological characteristics and prospecting clues of Ruoling gold deposit in Huangshan of Anhui |

| Abstract: | Ruoling gold mining area of Huangshan,lying at the eastern part of Jiangnan oldland in Yangtze landmass,is located inside the Mesozoic Cu-Mo-Au-Ag-Pb-Zn metallogenic belt (III-53)in Jiangnan massif of the lower Yangtze metallogenic province (II-1 1 ).Through mineral exploration works,several gold ore (mineralized)belts were found with the gold grade ranged from 1.27×10 -6 to 8.52×10 -6 ,and thus the au-thors believed that Ruoling area had favorable conditions for the mineralization of gold deposits.Based on the analysis of metallogenic conditions and geological characteristics of the ore deposits,the authors summarized the clues for prospecting of this type of gold deposits.It appears that the intersection part of NW-trending and NE-trending faulted structures in the mining area is a favorable position for mineralization and enrich-ment of gold and silver,and the wall rock alteration which is closely related to gold mineralization in the area can be categorized into silicification,pyritization and ferritization,and the types of ores include structural al-tered rock type and quartz vein type. |
