摘要
秋树湾角砾岩型铜(钼)矿位于北秦岭造山带南侧,含矿地层为秦岭群。铜矿体发育于秋树湾岩体外侧带的角砾岩中。角砾状黑云母片岩的REE具有洋脊拉斑玄武岩特征;稳定同位素组成显示成矿具多期性,流体具多源性,成岩环境热流值高;成矿流体特征指示成矿机制为多期流体叠加,流体成分及温度发生过剧变。
The Qiushuwan copper deposit hosted in Qinling Group lies in the south of the North Qinling orogenic belt. Ore bodies occur within the breccia and porphyry. The REE of breccia biotite schist represents feature of oceanic tholeiite. Isotope composition shows multi-stage minerlization,multi-source fluid and high thermeral current value of petrological environment. The fluid characteristics suggests the multi-stage superimposition of fluid and sharp cahnge of temperature.
