| 摘 要： | 柳林铀矿床位于华北地台与扬子地台的接合部位,大地构造上归属于秦岭褶皱系的桐柏-大别褶皱带。区内燕山期岩浆活动强烈,地质构造复杂,多数断裂具有多期次活动的特点,区域构造线方向呈北西西-南东东向展布。区内主要出露燕山期花岗岩,其北部出露上元古界苏家河群及信阳群,为一套变质岩系。通过勘查,柳林铀矿床受构造控制,为小型矿床规模。笔者在总结其地质特征、成矿规律的基础上,对矿床成因进行了探讨,并对矿区远景进行评价。矿区的1号断裂带、6号细晶岩脉是主要矿带,通过进一步勘查有望使矿床储量达到中型规模。

| Abstract: | Liulin uranium deposit is located in the interface of the North China-Yangzi platform. It belongs to Tongbai-Dabie fold belt of Qinling fold system. The district has undergone strong Yanshanian magmatic activity ,multi-period geological structure events. Regional structrual line in this area is north west-south east, the major outcrops are Yanshanian granite and some Upper-Proterozoic metamorphic rocks named Sujiahe group and Xinyang group occur in its northern part. Through exploration, a small uranium deposit has been discovered in Liulin and the deposit was founded to be controlled by structures. Based on the geological features and mineralization genesis research,the metallogenic pattern was discussed and prospecting potential was estimated. The fracture zone 1 and aplite belt No.6 are regarded as the target to find a middle scale deposit after further exploration. |
