摘要
460铀矿床是我国华北地台北缘一个有代表性的火山岩型铀矿床,该矿床研究对我国北方火山岩型铀矿找矿具有理论指导意义。本文从岩石化学、微量元素、稀土元素、铀钍演化、共生与伴生元素、稳定同位素、成矿温度及成矿年龄等方面研究了矿床的地球化学特征,并探讨矿床的成矿机理,建立矿床的成矿模式。
No.460 uranium Deposit is a typical volcanic uranium deposit in North China Platform.This paper studied its geochemistrical characteristics of microelements and rare earth elements,evolution of uranium and thorium, coexisting and accompanying elements,stable isotope and metallogenic temperature.In the end it analyzed the metallogenic mechanism and established a metallogenic model of the deposit. The studies were helpful to explore volcanic uranium deposits in North China.
