Abstract:Alaqitudong copper deposit is located in the Langshanmetallogenic belt,which is a newly discovered copper deposit in recent years. Through the systematic study of primary geological prospecting data and geochemical analysis means, the geological characteristics of ore deposits and orebodieswere analyzed, the genesis of ore deposits was discussed,and prospecting potential was analyzed.It has guiding and reference significance for prospecting in this area and its periphery.Research indicated that the deposit was controlled by the second lithologic section (Jxa2) of Agulugou formation, Zhaertaishan group, mesoproterozoic, orebody in silicified quartzite, quartz schist, alayered, the stratoid roughly bedding stratified output, affected by the late metamorphism and tectonic compression, bending along the strike and the tendency to form ore bodies crumpled, and formation and seam "reverse" phenomenon. Through the restoration of metamorphic rocks, it indicated that the surrounding rocks of the ore-bearing rocks were sedimentary sandstones, and the ore deposit was considered to be a sandstone type copper deposit, whichwas enriched by metamorphism and magmatic transformation.
