| 中文摘要: |
| 本文在论述“焦家式金矿”和“玲珑式”金矿床地质特征的基础上,进一步应用数理统计方法,对两种不同类型矿体的成矿元素和不同晶体形貌的黄铁矿特征进行对比。阐述了二者在空间分布关系上是属同源成矿物质,并在相同地质构造作用下,由不同性质的构造断裂控制的结果。 |
| 英文摘要: |
| A correlation study has been conducted on the spatial distridution relationship between Jiaojiatype and Linglong-type mineralizations in the Zhaoye gold zone using the mathematical statistics. It is believed that these two types of gold mineralization possess the same metallogenic process through the R-type factor analysis and corresponding analysis. The economic mineralizations are formed during a single metallogeic stage with dominant Au-bearing pyrite. In vertical change, the element assemblage is conformable, the upper part consists of Ag, As, Sb, Bi and cubicpyrite with simple crystal form {100}; the lower part is characteric of Zn, Mn and prevailing comdination pyrite with complicated crystal form {100}+{210}. The vertical zoning sequence of pyrite crystal is as follows (from upper to lower) : {100}→{111}→{100}+{111}→{210}→{100}+{210}, Which shows the gradual changes from rapid cooling to slow cooling for the forming temperature and the change from low to high for the supersaturation of S. These two types of orebodies are parallel in occurrence. The difference in the type is ascribed to the fracture structure of different features, sothe metallogenic materials should be cognate. |
