| 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 deposits. |
