| 摘 要： | 哀牢山成矿带位于云南省中南部,带内相续发现了墨江金厂、镇沅老王寨和元阳大坪等一批大型-超大型金多金属矿床。滇西南地区的莫霍面等深度特征、大陆地温梯度和大地热流高异常特征以及地球深层次结构特征,一致表明哀牢山地区在新生代处于强烈的壳幔相互作用时期。以大坪超大型金矿床同位素组成为例开展了示踪学研究,结果表明,成矿物质及成矿流体均以上地幔或下地壳来源为主,成矿过程中有少量地壳浅部的大气饱和水、岩浆水或它们的混合流体的加入。区域地球物理场特征及同位素示踪学研究一致表明,在哀牢山成矿带内矿床形成过程中,伴随有强烈的深部岩浆活动,壳幔相互作用对该地区矿床的形成有重要贡献。

| Abstract: | The Ailaoshan metallogenic belt is located in the middle-south part of Yunnan Province, where there are several large-superlarge gold-polymetallic deposits such as Jinchang in Mojiang, Laowangzhai in Zhenyuan and Daping in Yuanyang. Regional geophysical characteristics show that the NW-striking Ailaoshan metallogenic belt has a complicated crust-mantle structure. The Moho discontinu-ity isobath features reveal that the crust in the northeast is thicker than that in the southwest and represents a mantle-slop... |
