| Abstract: | The present paper discusses some important features of low-temperature deposits in an open struc-tural system by taking the Gongqiaoba Sr deposit for example. It is pointed out that the ore mineral as-semblage and walk-rock alteration are very simple, and hidden vertical zoning is recognized in theGongqiaoba deposit. The deposit was formed in a shallow-seated environment. The mixing of shallowmeteoric water and deep formation water resulted in the precipitation of ore-forming materials underthe low temperature condition. |
