| 中文摘要: |
| 文章从成矿地质背景和矿床地质特征入手,在分析成矿物质来源、金的地球化学性质、成矿物理化学条件和金的迁移-沉淀方式的基础上,提出了矿床成因的新观点,建立了新的成矿模式。认为河台金矿床的定位受韧性剪切带等构造因素的控制;成矿物质来源为多源,但主要来源于震旦系C组的地层;矿床成因类型属于韧性剪切带中的热动力变质+热液循环富集型金矿床。 |
| 英文摘要: |
| Hetai Au deposit is located in a ductile shear zone in Yunkai mountains in the west Guangdong province. The paper begins with the analysis of ore material source, geochemical property of gold, physiochemical condition of ore formation and transportation-precipition mechanism of gold. Then a new genetic view point and metallagenic medel of the deposit is put forth. The deposit location is controled by ductile shear zone and ore materials are multi-sourced but dominated by that from Sinian C bed. The metallogenic model is ductile shear zone+thermal dynamic metamorphison+hydrothermal fluid eirculation enrichment. |
