摘要
460矿床是火山岩型铀矿床。玻璃包裹体中裂变径迹研究表明:成矿岩体次流纹斑岩的原始铀含量为13.0ppm;裂变径迹测年龄法在强烈蚀变地区可以作为一种测年龄的有效辅助手段。
The deposit No. 460 is a volcanite type uranium deposit. The study on fission tracks in melt inclusions indicates that the initial uranium content in the subvolcanic rhyolite-porphyry in the ore-forming massif is 13.0ppm. The fission track dating is a useful supplementry method for dating in the strongly altered rock area,
