中文摘要:
      从分析铊的地球化学特性和成矿作用过程中铊与金密切共生及受共同矿化剂和沉淀富集剂制约的角度,阐述了铊的找矿意义不仅局限于微细浸染型金矿,而对于多数金矿,尤其是对具有后生热液成矿特征的金矿均具指示意义。通过分析铊的富集规律,提出Cl,F,S,C等也具有找矿意义。总结了铊勘查地球化学评价的主要方面,同时指出了铊作为地球化学勘查方法所存在的问题。
英文摘要:
      In this paper,on the analysis of geochemical characteristics of Thallium and the close paragenesis of Thallium with Gold as well as they both controlled by same mineralizer and depositing enrichments in mineralization,the significance of Thallium for prospecting gold deposits has been put forward. The significance not only for microfine dissminated gold deposits but also for all the gold deposits that have features of epigenetic hydrothermal mineralization. On the basis of enrichment regulation of Thallium, the prospecting significance of Cl, F, C, S have been proposed also. The main contents of evaluation and the problems in Thallium exploration geochemistry have been summarized
