Abstract: Pingran Village Cu-Ni Sulfide Deposit in Laos is located in Ma Jiang-Xam Nua island arc metallogenic belt.In mineral area,the stratum which croped out is Peihong groups metamorphic rocks,the lithology is greenschist and sericite schist.Regional Ma Jiang fault is characteristic of cutting deeply and frequent inheriting activity,The northwest faults are derived from Ma jiang fault,they are important the structure of controlling-rock and controlling-ore,controlled the distribution of mafic,ultramafic rocks and ore-body of copper-nickel sulfide.The early serpentinites are the only source rocks of copper-nickel sulfide mineralization.The ore-bodies occur in the Mafic-ultramafic rock body.These ore bodies look like quasistratified,lens,and nervation shapes, with transition or mutation relation to surrounding rocks.Base on systematical expatiations of the regional mineralization geological background,the geological characteristics and the genesis of ore deposits,apreliminary exploration of its ore prospects is proposed.
