Analysis On Potential Of Uranium In Qingqicai Area Southwest Of Taoshan Orefield

Qingqicai area is located at southwest of Taoshan orefeild.The predecessors has been implemented Leidoushi deposit,Taozhukeng mineral occurrence and a large number of abnormal zone in the region.The type of mineralization is dominated by silicified fracture zone.The research done by predecessors mostly in Leidoushi deposit,then research on the periphery is relatively weak.This research is based on the systematic arrangement of the data in the district,geological survey,geophysical and geochemical survey and trenching revealed,So as to further extract the deep mineralization information of the periphery of the ore deposit,the metallogenic regularity and ore controlling factors are summarized,assessing overall uranium potential,delineation of prospective areas.The main results are as follows:?1?Caijiang initially identified the Indosinian granite is rich in uranium rock,magmatic magmatic hydrothermal activity,a variety of dikes in lamprophyre based development,tectonic activity in the region frequently,two sets of faults in staggered cutting constitute the main tectonic research area,formed a relatively independent closed metallogenic system has a good metallogenic condition.?2?The delineation of the study area,geochemical anomaly,the content of eU and ²¹⁰Po anomalies are widely distributed,the two match rate is high,and it is consistent with the distribution of surface uranium mineralization,mainly along the NNE and NE trending silicified fractured zone was beaded distribution,clamp or cross and vein rock and fracture cross in composite parts fracture,halo is more obvious,that deep uranium mineralization information is clear and has good ore prospects.?3?The area generally find out ore control factors,the main ore controlling factors for fracture,lithology interface,lamprophyre veins and fracture of composite parts and ore mineralization enrichment site structure occurrence location,structure and variation of lamprophyre complex parts,tectonic bulge.It is clear that the main prospecting type is silicified fractured zone type uranium deposit.?4?Think on the basis of comprehensive analysis,the study area has good looking for similar mine uranium silicide Leidoushi crushing potential of uranium resources zone type uranium deposit and the delineation of the Qingqicai-Taozhukeng grade uranium pit 1 scenic spots,and according to the work area,degree of mineralization conditions and other conditions,can be further delineated for the pre survey,Qingqicai-Wangzhudou and Caijiang-Xiefang prospecting target 2 areas.Within the first grade prospecting area,1 large uranium mines can be put into practice,and 1 target areas of the middle size uranium deposits can be respectively located under the Qingqicai-Wangzhudou and the Caijiang-Xiefang target area.?5?Based on the work elements of degree in the district and the metallogenic conditions,according to the uranium metallogenic regularity,suggested in the Qingqicai-Wangzhudou,Caijiang-Xiefang and Leidoushi deposit periphery prospecting target area continue to carry out exploration work.
