| 中文摘要: |
| 野马沟铀矿床位于东昆仑成矿带上基底穹状隆起的塌陷式火山盆地中,是继该区域海德乌拉铀矿床后发现的又一个典型火山岩型铀矿床。研究区主要为断裂控矿,铀矿体赋存于NW向展布的F10逆断层中,含矿岩性为酸性火山岩。通过地面伽马能谱测量、活性炭剖面测量、伽马测井等放射性物探方法的应用,查明了放射性物探特征与含铀构造破碎带的空间配套关系,分析梳理了物探找矿思路,总结了物探找矿标志,圈出铀异常带10处,氡异常带4条,经地表及深部工程验证,累计发现铀矿(化)体16条,找矿成果显著。 |
| 英文摘要: |
| Yemagou U deposit is located in a collapse basin of quaquaversal dome uplifted from basement of the east Kunlun ore belt. It is a typical volcanic U deposit ensued discovery of Haidawula U deposit in the study area. The U ore body occurs in thrust fault F10. Acidic volcanics is the host rock. Active carbon profile survey and gamma well logging are carried out and is verified spatial match of radioactive exploration feature and the U ore-bearing cataclastic zone. We sort out the geophysical exploration thoughts and summarize geophysical prospecting marks. Ten U anomalies and four radon anomaly belts are located. The anomalies are checked by workings and 16 U ore (mineralization) bodies encountered. The Radioactive geophysical exploration is effective in the area. |
