Abstract: There are more than 800 modern hot-springs in western Sichuan, China, but few know ledge has been obtained about hot-spring mineralization. Some new analytical data of siliceous and calc sinters from Rekeng, Batang County, and Reshuitang, Litang County, are reported, indicating that gold mineralization in both area, with Au contents from <0.1 to 1.89g/t. Being high in Li, Be, Mo, Ga, Rb and Cd contents and low in Cu, Pb and Zn contents in sinters of gold mineralization can be used as an indicator for further prospecting. Terrestrial siliceous sinters are different from submarine chert for the highly input of Al and other landphile elements. So, some widely applied diagrams such as the Fe-Mn-(Ni+Co+Cu) diagram by P.A. Rona (1978,1988) can be used to discrimination its origin, but some can not be used directly, such as the Al-Fe-Mn diagram by Adachi et al.(1986). It is urgent to investigate and research the mineralization feature and metallogenic regularity related to the modern hotspring systems in western Sichuan and other sinters in the Sanjiang (Jinshajiang River, Nujiang River and Lancangjiang River) area.
