| 摘 要： | 扬子地块西南缘大面积低温成矿域的Au、Sb、Hg、As矿床,常出现共生分异的现象,在空间上形成Au、Sb、Hg、As矿床、矿带相伴出现而又相对独立的规律性分布。在详细研究Au、Sb、Hg、As矿床、矿带区域分布及其产出地质背景的基础上,从不同的角度,对制约Au、Sb、Hg、As矿床、矿带共生分异的因素进行了探讨。 |

| Abstract: | The association and fractionation phenomena of Au, Sb, Hg and As deposits located in the epithermal mineralization area at the southwestern margin of the Yangtze Block have been identified during mineralization. Although these epithermal deposits and ore belts are associated with each other, their spatial occurrence is of relative independence. The mechanism of association and fractionation has not been clear up to now. Based on the regional distribution and geological setting of Au, Sb, Hg and As deposits and ore belts, the mechanism of association and fractionation of these epithermal deposits or ore belts will be discussed in different aspects in this paper. |
| Keywords: | Southwest Yangtze Block epithermal mineralization area deposits of Au Sb Hg and As association and fractionation |
