| 中文摘要: |
| 通过在豫西地区龙王岩体运用放射性伽马测量、放射性测井等工作手段,圈定放射性异常点及异常带,结合地表槽探揭露及深部钻探验证,证实稀土矿(化)体与放射性异常套合较好。根据光薄片、化学分析等方法,对比槽探和钻孔取样分析结果得出:放射性强度与稀土总量之间具有正相关的关系结论；引起放射性异常的主要元素为Th,是产生放射性的主要原因。因此,利用放射性物探方法在豫西地区寻找稀土矿,是有效且直接的找矿手段,利用此方法有望在豫西地区及河南省其他地区寻找稀土矿,取得新的找矿突破。 |
| 英文摘要: |
| Through the use of radioactive gamma measurement, radioactive logging and other working methods in Longwangzhuang rock mass in western Henan Province, the radioactive anomaly points and abnormal zones were delineated. Combined with the surface trenching exposure and deep drilling verification, it was confirmed that the rare earth ore (chemical) body and radioactive anomaly are well matched. According to the methods of optical thin section and chemical analysis, the comparison of the results of trenching and borehole sampling analysis shows that there is a positive correlation between the radioactive intensity and the total amount of rare earth. The main element causing the radioactive abnormality is th, which is the main cause of radioactivity. Therefore, it is an effective and direct prospecting method to search for rare earth deposits in western Henan Province by means of radio geophysical prospecting. This method is expected to find rare earth deposits in western Henan and other areas of Henan Province, and make a new breakthrough in prospecting. |
