The δ〓O for both of them are changed due to water/rock interaction at water/rock weight ratios of larger than 0.1, and the calculation indicates that, in this case, the influence of water/rock interaction on the δD value of the fluid is minor. In the upper part of the geothermal system, the upward ore forming fluid mixes with low temperature groundwater with very low salinity and δ〓O, which may cause the precipitation of metals.

根据氢、氧同位素研究结果，嵩溪银锑矿床的上升成矿流体是由岩浆热液与循环地下水热液混合而成，这种混合成因含矿热液上升到地热系统上部与低矿化度、低δ〓O的低温地下水发生了不均匀混合，这种混合作用导致金属矿物沉淀，但成矿物质是由上升成矿流体带来的。
