| 摘 要： | 民和盆地铀矿地质工作程度较低，前人在盆地边缘已发现了一些砂岩型铀矿化和大批航测铀异常，显示了一定的找矿前景，本文以区域地质背景为基础，通过对高精度航磁、航空放射性（简称“航波”）和布格重力资料进行解释，结合对盆地水动力，岩相古地理与古气候的分析，对盆地砂岩型铀矿成矿条件进行了综合研究，并指出了成矿的有利区段。

| Abstract: | Little uranium prospecting has been performed so far in Minhe basin. However, at the marginal areas of the basin uranium mineralizations and lots of aeroradioactive anomalies have been found before, and the basin shows some prospecting potential. Based on the regional geological setting, by means of interpretation of high precision aero magnetic, aeroradiometric and Bouguer gravimetric data, and combined with hydrodynamic, lithofacies paleogeographic and paleoclimatic analyses, authors of this paper make a comprehensive evaluation of metallogenic conditions for sandstone type uranium deposits, and propose metallogenically favourable areas in the basin. |
