多覆盖地区花岗岩接触带及其控矿特征的遥感研究

MULTISPECTRAL REMOTE SENSING FOR THEGRANITIC CONTACT BELT IN THE AREAOF VEGETATION AND SOIL COVERING

本文主要介绍应用ＴＭ图像对西秦岭地区的中川岩体进行研究的成果，即研究在多植被、多黄土覆盖的复杂条件下，如何依据接触带蚀变岩的遥感图像像元亮度值及实验室测得的光谱曲线特征，区分不同的岩体接触带类型，并探讨它们对金矿的控制作用。

he paper studies the Zhongchuan granitic mass with TM imagery in the Western Qinling of China. Under the conditions of the vegetation and loess covering, according to pixel and laboratory Spectrum, different contact metamorphic rocks were identified. The paper also discussed the control factors of exo-contacts to the gold mineral deposits.
