本文应用遥感图像解译,结合地质、物探、化探成果,对滇东南地区隐伏的花岗岩体及其有关的钨、锡矿床进行了预测。通过分析遥感图像,在滇东南地区显示了一批新的断裂构造,并且可修改和补充原有的一些断裂构造。与此同时还判别同一断裂在不同时期、经受不同的构造运动后,其力学性质是会转化的;在同一断裂不同的构造部位,其力学性质也往往不尽相同。很少出现单一力学性质的断裂存在。本文所称的环状构造,推其成因,认为多数与岩浆的脉冲作用有关,大都是岩浆有关的热点活动的结果。这就为预测与花岗岩有关的钨、锡矿床、开辟了新的途径。环状构造与其它构造(如断块构造等)复合时,对寻找隐伏花岗岩体及其有关的矿床更为有利。本区共圈出20个环状构造。初步认为与隐伏花岗岩体和钨、锡矿床有关的环状构造共8个。所预测的环状构造是否正确,有待于今后工作中验证。然而,在本区利用环状构造,结合地、物、化成果预测隐伏花岗岩及其有关的钨、锡矿床,为了提供新的找矿线索,缩小找矿的,“靶区”减少工作的盲目性,是应用遥感图像的新的尝试。
In this paper, remote sensing image interpretation, combined with the geological, geophysical and geochemical exploration results, to conceal the granitic granites and related tungsten and tin deposits in southeastern Yunnan. By analyzing remote sensing images, a number of new fault structures have been shown in the southeast Yunnan region, and some of the original fault structures can be modified and supplemented. At the same time, it is also found that the mechanical properties of the same fault will be transformed after being subjected to different tectonic movements in different periods. In different tectonic parts of the same fault, the mechanical properties are often different. Few fractures of a single mechanical property are present. In this paper, the ring structure, push the genesis, that the majority of the pulse and the role of magma, mostly the result of hot magmatic events. This opens up new avenues for predicting the granite-related tungsten and tin deposits. Ring structures, when combined with other structures (such as faulted blocks, etc.), are more favorable for the search for buried granitic bodies and their associated deposits. A total of 20 circular structures are circled in this area. It is preliminarily thought that there are 8 ring structures related to concealed granite, tungsten and tin deposits. Whether the predicted ring structure is correct needs to be verified in future work. However, in this area, the use of the ring structure, the combination of geology and geochemistry to predict the concealed granite and its associated tungsten and tin deposits, and in order to provide new ore-prospecting clues and narrow the prospecting, “target area” to reduce the blind work Sexuality is a new attempt to apply remote sensing images.
