本工作采用仪器中子活化分析对不同产铀岩体、非产铀岩体、铀矿床不同蚀变带中的锆石及其经过浸泡的不同颜色锆石进行了微量元素测定。 1.实验 本工作采用相对比较法对多种不同类型或浸泡过的锆石进行了分析。 1).样品与标准的制备 为了选出纯净的单矿物锆石,首先将岩石样品粉碎至60目,然后在高倍显微镜下选出纯净的锆石大约40mg,用分析纯的氢氟酸(pH=2)浸泡锆石来制得浸泡锆石样品。浸泡及未浸泡的锆石单矿物均在90℃的干燥箱内干燥12小时。
In this work, the neutron activation analysis was used to determine the trace elements of zircons from different types of uranium rocks, non-produced uranium rocks and different alteration zones of uranium deposits and their different soaked zircons. 1. EXPERIMENT This work uses a comparative method to analyze many different types or soaked zircons. 1). Preparation of Samples and Standards In order to select pure single-mineral zircons, the rock sample is first pulverized to 60 mesh and then approximately 40 mg of pure zircon is selected under a high magnification microscope. The pure hydrofluoric acid = 2) Soak the zircon to make a soaked zircon sample. Soaked and un-soaked zircon single minerals were dried in a 90 ° C oven for 12 hours.
