| 中文摘要: |
| 本文主要探讨新疆阿尔泰地区多拉纳萨依、沙尔布拉克等成型金矿床的成矿物质来源。从金元素在矿体及围岩中的地球化学性质,黄铁矿含金性及Q型聚类分析,成矿流体化学成分特征三个方面探讨了矿床的成矿物质来源;从成矿流体的氢氧同位素方面探讨了成矿溶液的来源,从而得出区内金矿成矿元素主要来源于围岩;成矿流体具多来源,但富矿体形成阶段以大气降水为主的结论。 |
| 英文摘要: |
| This paper deals with source of gold in the gold deposits in Altai Area. Results obtained show that gold contents are high and variable. Coefficients are higher for Middle Devonian and Lower Carboniferous stratum. Enrichness and poorness of gold are coupled about ore bodies with alteration zonation. Data of pyrite with high gold value within ore body are closely related to those within the direct wallrock.Ore fluid is rich in Ca++,HCO3- and SO4—— et. al.,and similar chemically to wallrock. All the results suggest that ore materials are mainly derived from wallrock. |
