Abstract:

Hongshiquan uranium deposit is located in pegmatitic kali granite which intruded upside strata of Longshoushan group in Lower Proterozoic basement fold zone.The existence of uraninite is mainly uraninite,secondly pitch blende and residual uranium black.By chemic full analysis and correlation matrix analysis,P₂O₅、TiO₂、MgO、Fe₂O₃、MnO、Tignition loss are greater positive relativity to uranium.Multiple correlation coefficient of metallogenic age is 0. 9999 by three phase model,which indicates the metallogeny close to diagenism era,belongs to the product of Lvliang movement.Biotitization is primary mineralization phase,there are zircon and clipper built inclusions in biotite.The deposit genesis should be multiphase replacement hydrothermal deposit that concerns with migmatitization in combine diagenism phase migmatitization and mineralization phase.According to formation process of deposit,the uranium source mostly comes from deep lava and siliceous kaliceous solution.

Key words: Hongshiquan uranium deposits, Mineralization, Genesis of ore deposits
