Method for confirming alteration temperature of green alteration sandstone

The invention belongs to the technical field of uranium ore, and particularly relates to a method for confirming alteration temperature of green alteration sandstone. The method comprises the following steps: step 1, collecting a sample; step 2, obtaining a uranium-containing experimental medium; 3, carrying out green alteration sandstone simulation experiments under different temperature conditions; 4, taking out an experimental sample in the step 3 after the experiment, cleaning, drying in a drying oven at 50 DEG C, and observing the sandstone color; and 5, observing the red sandstone and the alteration product thereof by using a scanning electron microscope. The determined alteration temperature of the green sandstone is high in credibility, and a first-hand experimental data support is provided for deepening the sandstone type uranium mineralization theory. 本发明属于铀矿技术领域，具体设计一种确认绿色蚀变砂岩蚀变温度的方法。本发明包括以下步骤：步骤1、样品采集；步骤2、获得含铀实验介质；步骤3、不同温度条件下绿色蚀变砂岩模拟实验；步骤4、实验后取出步骤3实验样品，清洗后50℃烘箱烘干观察砂岩颜色；步骤5、利用扫描电镜观察红色砂岩及其蚀变产物。本发明确定
