Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0039] This embodiment takes the judgment of thermal reformation temperature in the northeastern part of the Ordos Basin as an example, and provides a method suitable for comprehensive judgment of thermal reformation temperature of sandstone-type uranium deposits, which specifically includes the following steps:
[0040] Step 1. Sample collection and preparation of optical thin sections and inclusion rock thin sections
[0041] Collect a set of sandstone-type uranium deposit samples, including: ore-forming surrounding rocks and ore samples of different colors and grain sizes; after removing the impurities and weathered skin on the sample surface, grind the sample into a size of about 40mm×20mm and a thickness of about 0.03mm The light thin section and the inclusion rock thin section with a size of about 40mm×20mm and a thickness of 0.1-0.3mm a...

The invention belongs to the field of uranium ore metallogenic prediction, and particularly discloses a method suitable for comprehensive judgment of the thermal transformation temperature of a sandstone type uranium deposit. The method comprises the following steps: step 1, collecting a sample and preparing a polished slice and an inclusion rock slice; step 2, selecting chlorite and inclusion measuring points; step 3, carrying out chlorite component determination and formation temperature calculation; step 4, measuring the uniform temperature of the fluid inclusion; and 5, comprehensively judging the thermal transformation temperature. According to the method, an electronic probe analysis technology is utilized, the geochemical characteristics of the minerals are accurately determined, and the thermal transformation temperature of the sandstone type uranium deposit is comprehensively and objectively judged.
Description
technical field [0001] The invention belongs to the field of uranium ore metallogenic prediction, and in particular relates to a method suitable for comprehensively judging the thermal reformation temperature of a sandstone type uranium deposit. Background technique [0002] Sandstone-type uranium deposits have become the most important type of industrial uranium deposits in the world and in my country. It is generally believed that sandstone-type uranium deposits are dominated by interlayer oxidation or phreatic oxidation. Exploration practice in the past 30 years has shown that the Paleo-Asian orogenic belt across northern China and the Mesozoic-Cenozoic continental sedimentary basins on both sides are the most important ore-forming tectonic domains for the formation of sedimentary uranium deposits in my country, from west to east There are five sandstone-type uranium deposits in Yili, Tuha, Ordos, Erlian and Songliao. The sandstone-type uranium deposits discovered in the...
