摘要
通过分析梁河盆地水文地质特征、古水文地质特征和水文地球化学特征,列举了对铀成矿有利和不利因素,认为盆地盖层南部诸多因素决定其不利成矿,盆地盖层北部地层剥蚀严重,构造发育,具有形成砂岩型铀矿床的潜力,但不利因素决定其成矿规模非常有限。北部地区地热丰富,有利于形成热液型铀矿床。
This paper deals with favorable and unfavorable factors of uranium mineralization in the Lianghe basin based on hydrogeological,palaeohydrogeological and hydrogeochemical characteristics.Geological and hydrothermal conditions in the north are favorable to the sandstone-type uranium mineralization because of developmental structure or to hydrothermal uranium mineralization thanks to developmental geothermal fluids.
