According to measured data of more than 50 inclusions in the ores from 12 depos i ts in western Guangxi and adjacent area, the authors complied a deuterium contou r map for the study area. It is shown that most of the ore deposits show an integrity and unity in the oreforming p r ocess of meteoric water. The deposits can be classified into two types: one with the oreforming solution originated directly from meteoric water, and another d erived mainly from sedimentary water.
