The characteristic compositions of the stable isotopic and the fluid inclusions in Maoping mineral district show that the main sources of Pb origin the Upper Earths Crust, partly froin orogenetic belt and/or Emeishan basalt; the S isotopic composition hints sulfur sources from the seawater; The D and O isotopic compositions show that they emerge from the compound results of the magma water, metamorphic water, hosted water and rain water; the origination of the C isotopic shows that C resource strata.

脉石矿物D、O同位素组成代表了岩浆水、变质水、建造水及大气降水混合作用的结果；C同位素组成则反映来自受热液改造的含有机质的地层，说明地层受成矿流体溶解、淋滤、萃取而提供了部分成矿物质和储矿空间。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.

目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式，一是运用同位素地质温度计原理，利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系，对湖泊古水温做定量研究；二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温；三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。
