某区放射性水文地球化学特征及其地质意义

文章通过对某区放射性水文地球化学特征的研究,探讨了矿化水的成因和基本特征,铀在溶液中的存在形式,含铀水迁移强度;铀和氡在水中的迁移距离;水化学组分与矿化的关系。总结了工作区的放射性水化学找矿标志和评价水晕的综合判别准则。在研究的基础上,预测了新的成矿远景地段,提出了现有矿床可能属于后生气热水改造复成因矿床的假说以及根据这些假说似算这类矿床铀总量的方法。

RADIOHYDROGEOCHEMICAL CHARACTERISTICS AND ITS GEOCHEMICAL IMPLICATION IN. A CERTAIN REGION

Based on the study of radiohydrogeochemical characteristics in a certain arca, this paper considers the genesis and fundamental features of mineralized water, forms of uranium occurrence in solutions, degree of uranium migration in water, transporting distance of uranium and radon in water and relationship between hydrochemical components and mineralization. Radiohydrochemieal prospecting guides and comprehensive recognition eriteria for the assessment of water halos in the study region are summarized. On the basis of these studies, new metallogenic prospective areas are predicted; the hypothesis that the existing ore deposits may belong to an epigenetic, pneu-mato-hydrothermal reworking and Polygenetic types is proposed and the method of calculating the total uranium amount from this kind of ore deposit, is presented according to the hypothesiS.
