根据蚀变岩的TM波谱特征,在日土县以东地区进行了蚀变岩遥感信息提取。通过对研究区羟基(OHA)和铁染(FCA)两种异常的分析,为下一步地质调查工作提出建议。 更多还原

【Abstract】 According to the TM spectral signatures,the remote sensing information has been abstracted from the remote sensing image of the alteration rocks east of Rutog,Xizang.The remote sensing anomalies of alteration rocks comprise hydroxyl anomalies(OHA) and ferric contamination anomalies(FCA),and may have a genetic link with subaqueous hydrothermal events,regional metamorphism and weathering.The remote sensing information in this study is of importance for probing the genesis of hydrothermal ore depos... 更多还原
