【摘要】 内蒙古花山405矿点的微量和稀土元素能为铀矿勘查提供地球化学标志。通过对该地区矿化岩石和围岩分别采样,共对30个微量元素和14个稀土元素进行了对比分析,总结了该地区微量元素和稀土元素的地球化学特征。研究表明,该山群富集W、Re、Ba、Th、U、Pb等元素,而Li、Be、V、Ni、Cu、Rb、Zr、Nb、Mo、In、Cs、Tl、Bi等元素亏损;微量元素在矿化岩石中含量较高,在围岩中相对贫化;此外,该地区稀土元素地球化学特征表现为轻稀土富集,重稀土亏损;Eu在铀矿化岩石中显示弱正异常,在围岩中显示弱负异常,Ce基本没有异常。更多还原

【Abstract】 The Inner Mongolia huashan 405 mineralization section of trace and rare earth elements can provide uranium exploration geochemical mark.Through to the region mineralized rocks and surrounding rock separate sampling,a total of 30 trace elements and rare earth element 14 carries on the contrast analysis,summarizes the region trace element geochemical characteristics.Research shows that the mountains enrichment W,Re,Ba,Th,U,Pb and other elements,and Li,Be,V,Ni,Cu,Rb,Zr,Nb,Mo,In,Cs,Tl,Bi,etc element loss;Trace elements in the mineralized rocks content is higher,in the surrounding rock relative depleted;In addition,the area of rare earth element geochemical characteristics for light rare earth concentration,heavy rare earth losses;Eu in uranium mineralization in the rock show weak positive anomaly,in surrounding rock shows weak negative anomaly,Ce basic no exception.更多还原
