| 摘 要： | 本文通过氢氧同位素、硫同位素及微量元素的测试分析,结合矿田地质背景对成矿物质来源进行了分析,认为里伍铜矿田成矿物质主要与燕山期＂S＂型花岗岩的侵入作用有关。在岩浆侵入过程中,由于热作用的驱动,岩浆热液携带部分成矿物质,沿一定的通道上升或运移,并不断与围岩发生物质的带出和带入,成矿流体是以岩浆热液为主的多组份的热液体系。

| Abstract: | The Liwu copper orefield in Jiulong,Sichuan tectonically lies in the Jianglang metamorphic core complexes.The detailed examination has been made for the origins of the ore-forming matter from the Liwu copper orefield on the basis of hydrogen,oxygen and sulfur isotopes,trace elements and geological background.The origins of the ore-forming matter are believed to be associated with the intrusion of the Yanshanian S-type granites.The magmatic hydrothermal fluids with the ore-forming matter migrated upwards alo... |
