| 中文摘要: |
| 近年来在滇黔桂交接地带已发现微细浸染型金矿床(点)和矿化异常100余处,并己找到若干大型矿床,证明这一带为我国进一步寻找这类金矿的有望远景区。本文据已知矿床和区域地质资料的综合研究,对该区微细浸染型金矿成矿控矿的地质、构造、物理及化学条件进行了论证,确定矿床为低温渗滤热液型金矿,初步建立了成矿地质概念模式,提出了四大成矿带和十三个成矿远景区,为本区扩大找矿提供了依据。 |
| 英文摘要: |
| Micro-fine disseminated gold ore deposit are discovered in recent years, mainly distributed at the triangle area of Yunnan, Guizhou and Guangxi Provinces, for example, Banqi, Yata, Zimudang and Getang gold ore diposit in the southwest Guizhou Province, the large sized deeposits of Jinya and Gaolong in northwest Guangxi Province and the gold ore deposits and gold occurrences in southeast Yunnan Province.Based on the previous works this paper make a systematic analysis of metallogenic conditions of structure, ore-bearing horizons, heat source for gold mobillization and physico-chemical environment for gold concentration and the features of the gold ore deposits. The deposits in the triangle area are classified into epithermal filteration type of gold ore deposit and a general metallogenic model is primarily proposed. Furtherly, four metallogenic belts, ie. Nanpanjiang belt, Youjiang belt, Milie-sizong belt and 13 prospect areas are defined. |
