- Abstract
The ore-bearing rocks of Bashibulake deposit are dense and hard, with strong epigenetic transformation and complex uranium mineralization. The analysis on its characteristics will provide theoretical basis for uranium metallogeny in this area. Through the combination of ground investigation and drilling data, with the help of micro-geochemistry, it was considered that the ore-bearing section of the Bashibulake deposit mainly experienced four types of superposition and transformation: oxidation, oil and gas reduction, dolomitization and hot brine interaction. Based on the analysis of uranium metallogenic conditions, it was proposed that the uranium mineralization in the study area underwent four stages. The multi-stage oxidation has laid a good foundation for uranium mineralization. The mid-term oil and gas action caused some oxidized rocks to fade and increase the adsorption of the target layer resulting in the high-grade uranium ore bodies distributed in the range of asphalt. The late-stage reduced hot brine continues to adsorb uranium elements in uranous-oxigenous water, and uranium elements were further enriched in the parts where the hot brine produced strong effect, therefore the uranium and metal elements have obvious spatial association.
