摘　　要：通过遥感图像地质解译 ,发现崇安地区存在一较大的环状构造。经区域地质分析和野外验证 ,该环状构造始成于加里东期 ,以后又有多次活动 ,燕山晚期活动最强。在环状构造的影响下 ,形成了古楼———麻沙透镜状地质体 ,成为该区铀矿化分布的区域控制因素 ,从而形成一个独立的成矿单元。其中铀矿化和异常片的分布大致显示了中心对称和两翼对称特点 ,成矿远景好 ,今后应深入加强深部找矿工作。A large ring structure has been discovered in chong'an region on the basis of geological interpretation of remote sensing images. The data acquired from analysis of regional geology and in-situ investigation indicate that the ring structure is initiated during caledonian and activated for several times afterwards; It displays the highest activity during Yanshanian. Under the effect of this structure, Gulou-Masha lenticular geological body was firmed, controlling the regional distribution of uranium mineralization and anomalies occur in forms of central and bilateral symmetry. The data indicate that it is prospective to prospect uranium deposit in this region; therefore, more work should be placed on the deep levels.
