摘　　要：本文借鉴“深源成矿”理论 ,提出在预测成矿远景区时应重视断裂构造的作用 ,并在对松辽盆地西南部已知铀矿床分析后认为 ,该矿床的形成与断裂构造和油气还原作用有关。参照已知矿床的地球物理特征 ,根据松辽盆地西南部的地球物理场及断裂构造特征 ,笔者提出了该区的找矿方向 ,并对下一步研究工作的重点及可能的有利远景地段提出了建议。Referring to the deep-sourced metallogenic the ory,this article proposes that attention should be paid to the fault structure d uring forecasting U-metallogenic prospect of the region.Meanwhile,based on the analysis of the known uranium deposit in southwestern part of Songliao basin,aut hors proposes that the formation of uranium deposit is related to the fault stru cture and the reduction of oil and gas.Finally,exploration direction for sandsto ne-type uranium deposits in the region is recommended,and some priority work in the future and 4 promising areas are proposed on the basis of comparing the geo physics features and fault structure characteristics of the known uranium deposi t with those of other areas in the southwestern part of Songliao basin.
