| 摘 要： | 桦树沟铜矿是镜铁山矿区与铁矿共生的铁铜矿床,其产出受后期韧性剪切带和层间滑动带共同控制.主要矿石类型有含铁碧玉岩型和蚀变千枚岩型.矿石及含矿岩系的稀土元素、稳定同位素等地球化学研究表明,铜矿床形成于近陆地边缘的海底裂谷环境,成矿物质来自基性火山岩,硫、碳主要来自海水.矿床成因属与海相火山作用有关的沉积变质热液叠加改造矿床.

| Abstract: | The Huashugou copper ore is the commensal ore in the iron-copper deposit in Jingtieshan iron mine and is cortroled obviously by ductile shear zone and interformational sliding. Jaspilite and altered phyllite are the main ore types. The geochemistry researches for the ore and the REE and stable isotope of the ore-bearing sequence indicate, the copper deposit formed at the submarine rife environment near-conti-nental margin, and the ore materials come from basic volcanics, and that the sulfur and carbon mostly come from seawater. The deposit belongs to metamorphosed sedimentary hydrothermally-reworked deposit related to marine volcanism. |
