探析松辽盆地瞻榆地区水文地质特征

Analysis on The Hydrogeological Characteristics of Zhanyu Area in Songliao Basin

【目的】充分搜集煤田部门探井测井资料,结合前人在松辽盆地铀矿找矿资料文献,开展煤田钻孔放射性找矿信息二次开发利用,分析区域水文地质特征,寻找有利于放射性找矿的水文地质线索。【方法】主要采取放射性水化学测量、水质分析、前人水文地质资料分析及综合利用等方法。【结果】对研究区水文地质特征,地下水补、径、排条件,放射性水化学特征及一些水文地质参数进行了取样统计,并对工区水文地质条件进行分析。【结论】研究区水文地质综合条件有利于地浸砂岩型铀矿成矿。

[Purposes]This paper,based on the previous uranium prospecting data and literature in Songliao Basin,fully collects the exploration well logging data of coalfield departments,makes the sec⁃ondary development and utilization of the coalfield borehole radioactive prospecting information,ana⁃lyzes the regional hydrogeological characteristics,so as to find the hydrogeological clues that are benefi⁃cial to radioactive prospecting.[Methods]Chemical measurement of radioactive water,water quality analysis,hydrogeological data analysis and comprehensive utilization are adopted.[Findings]The hy⁃drogeological characteristics,the recharge and discharge conditions of groundwater,the chemical charac⁃teristics of radioactive water and some hydrogeological parameters are sampled and analyzed.[Conclu⁃sions]The comprehensive hydrogeological conditions in this area are favorable to the mineralization of in-situ leached sandstone-type uranium deposits.
