| 中文摘要: |
| 经研究发现,桂西北地区主要微细浸染型金矿床具有独特的剖面组合结构,由下往上为巨厚生物碳酸盐岩层、滑塌层、细粒浊积碎屑岩层,金矿体产于浊积岩中;认为此剖面组合结构是金矿成矿作用的宏观地质表现。金矿床的形成应具备物质来源、矿液通道及成矿场所三个条件。 |
| 英文摘要: |
| Based on our work,we discovered that the micrograined disseminated sold deposits in northwestern Guangxi is charactered by its individual profile composite characteristics,which consists of thickbedded bioclastic carbonate rock layer,slump sheet, fine-grained turbidites hosting gold orebody from bottem to top. It is thought that the profile composite must be a macroscopic geological show of the gold ore forming process. There are three metallogenic conditions which are material source, ore-fluid channel way and metallogenic location for the formation of gold ore deposits. |
