摘  要:
通过对ETM+不同波段光谱特征进行分析,采用波段比值和主成分分析综合法,确定研究区铁蚀变指数。利用遥感蚀变异常下限值的定量模型,提取区域内的铁化蚀变信息。结合地质背景下有关构造特征、含矿建造、岩浆活动、矿化蚀变等示矿要素,圈定出两个成矿靶区,为研究区的蚀变信息定量提取和成矿区的预测提取提供了新的思路。

摘  要:
According to spectral characteristics of ETM + different bands in the research area, the ferrous mineralization alteration index was built based on the band ratio and principal components analysis. A quantitative model to calculate the lower range value of alteration anomaly was summarized, which solved the issue of quantitatively extracting alteration information. Two mineralization targets were delineated on the basis of tectonic characteristics, magmatism, ore -bearing formation, mineralized alteration and other ore-controlling factors. This method provided a new approach to quantitatively extracting mineralized alteration information and metallogenic prediction.
