| [摘要]老寨湾金矿位于云南省东南部,地处著名的“滇黔桂金三角”冶内,是云南迄今为止唯一进
行详查并大规模开发的“卡林型”冶金矿。现已探明矿床规模为中大型,目前,矿山已建成云南省首座吨金
矿山,具有良好的成矿条件和找矿前景。本文通过对矿区地质背景、地质特征、地球化学特征、矿石特征
进行了分析,推断矿床成因为后期热液改造形成,属沉积型后期热液改造微细粒金矿床。 |

| Abstract:The Laozhaiwan gold deposit is located in southeast of Yunnan Province, within the famous " Golden Triangle in Yunnan, Guizhou and
Guangxi"郾So far it is the unique "Carlin type" gold deposit that has been surveyed in detail and exploited on a large scale郾At present it has been deter鄄
mined that this deposit is of intermediate-large size, and constructed into the first gold mine of ton-level in Yunnan Province, exhibiting good mineraliza鄄
tion conditions and ore-search prospect郾In this article, we analyze the geological setting, geological characteristics, geochemistry and ore features of this
deposit郾We suggest that its genesis is associated with hydrothermal reformation in the later period, and it is a micro-fine grain gold deposit of the sedi鄄
mentary type郾 |
