| 摘 要： | 在斑岩型铜矿资源潜力评价中,斑岩体是圈定铜矿最小找矿预测区的重要依据。研究表明,遥感图像上的许多环形影像与岩浆活动(包括斑岩体)有关。为了快速进行斑岩型铜矿成矿预测,利用遥感技术在西藏玉龙—马拉松多斑岩型铜矿周边地区开展了找矿预测。首先建立了环形构造的遥感解译标志;然后开展了环形构造的解译工作,研究了该区环形构造的展布特征;最后总结了由环形构造推断斑岩体的标志。结果表明,遥感解译的环形构造为该区斑岩型铜矿最小找矿预测区的圈定提供了重要依据。

| Abstract: | Porphyry is an important basis for delineating the smallest prospecting area in resource potential evaluation of the porphyry copper deposit.Studies show that many remote sensing circular structures have a relationship with the magmatic activity(including porphyry).In order to evaluate ore potential of the porphyry copper deposit rapidly,the authors made ore prognosis in the Yulong-Malasongduo porphyry copper ore district by using remote sensing technique.Firstly,on the basis of ETM+ images,the circular structure indicators were established.Then,the circular structures in the study area were interpreted,the distribution characteristics of circular structures were summarized,and the deductive indicators of porphyry from circular structures were determined.The results show that circular structures can offer an important clue to delineating the smallest prospecting area of the porphyry copper deposit. |
