西南三江成矿带中段羊拉铜矿体南延问题研究与找矿预测
|
摘要
羊拉铜矿是金沙江成矿带内规模最大的铜矿床。文章在大量分析研究前人在该区已有工作成果的基础上,综合分析羊拉铜矿区及其南部地区已有地表工程及深部工程成果,从地层、构造、岩浆岩、地球物理、地球化学特征及遥感影像特征等方面对羊拉铜矿及其南部通吉格-虽丁-加仁地区铜矿床(点)成矿地质特征进行对比研究,认为羊拉铜矿体往南进行了延伸。同时通过对羊拉铜矿以南地区铜矿床(点)成矿条件、控矿因素和矿化分布特征等进行总结,初步建立了羊拉铜矿以南地区铜矿体成矿模式,并依据成矿模式和地质条件进行了找矿预测,提出了格日-通吉格找矿靶区及虽丁-加仁找矿靶区。
The Yangla copper deposit in northwestern Yunnan is the largest copper deposit in the NujiangLancangjiang-Jinshajiang metallogenic zone. Referenced to the previous results in integration with the surficial and deep-seated engineering results,the present paper gives a comparative study of the mineralization and geological conditions of the Yangla copper deposit and the southern Tongjige,Suiding and Jiaren copper deposits( ore spots)on the basis of regional strata,structures,magmatic rocks,geophysics,geochemistry and interpretation of remote sensing images. The authors in this study contend that the Yangla copper deposit is extended southwards indeed. The detailed study focuses on the metallogenic conditions,ore-controlling factors,mineralization distribution,and a mineralization model is presented for the areas south of the Yangla copper deposit. Two exploration targets have been distinguished,including the Geri-Tongjige and Suiding-Jiaren exploration targets.
