Ruoergai Uranium Ore Field Ore-forming Geological Conditions And Resource Potential Analysis

Ruoergai uranium ore field is located in south qinling metallogenic belt of the west,the main deposit type for carbon silicon mudstone type uranium deposits,have been included in the national second batch bulk exploration area.Have found two large uranium deposits,the medium and small uranium deposit.In the full collecting and sorting previous data and analysis test,on the basis of the study area in sichuan province,based on the exploration of uranium equipped with the latest achievements,from the zoige uranium ore field geological characteristics of the mineralization,through the area and typical uranium deposit system research,the analysis,summarizes the uranium deposit of metallogenic regularities and prospecting indicators,the establishment of a prospecting model.And based on the metallogenic prospective area of the division,forecast the whole field of uranium resource potential.Get the main achievements and know is as follows:The first study to make sure the ore-forming geological background,system analysis formation,structure,magmatism and physicochemical remote and mineral characteristics,summarization of metallogenic regularities,analyzes uranium deposits by strict strata,lithology and tectonic control characteristics.Secondly,through the ZhongChang groove and LuoJun groove typical uranium deposit geological characteristics,metallogenic geological conditions for material summary analysis,found the two uranium in the above aspects have comparability,the paper concludes that the ore-forming material comes from crust or next Paleozoic(silurian system)formation;Metallogenic hydrothermal from deep fluid and atmospheric precipitation mixing,hybrid;In the fluid transport process of activation,extraction of uranium surrounding rock,in appropriate secondary tectonic fracture zone and favorable limestone,silicon(carbon)limestone of precipitation and enrichment,and later through near surface modification effect,further enrichment.The uranium deposit should be with multiple source multiphase multistage composite superposition cause deposit.Finally,from the acidic intrusive body characteristics,structure intersection characteristics,lithologic combination,geophysical and geochemical exploration anomaly,the mine condition,this paper discussed summarizes this prospecting model for mineralization vision provides a basis for the division,after this study were divided three grade 8 metallogenic prospective area.Based on 8 metallogenic prospective area to ore prospecting and prediction,a total of prediction of all kinds of resource of 16000 t,has the good ore-prospecting potential,and can satisfy the monoblock exploration project implementation,assure to finish the expected goal task.
