【摘要】 基于地面高精度磁测资料对研究区断裂构造进行了探究，以期为后续物探工作探测断裂尤其是马路沟断层的深部发育特征提供依据，提升铀矿地质勘查效果与效益。通过对研究区ΔT磁异常与磁场特征分析，结合地质、岩石磁性参数与断裂构造磁异常判别标志，解释断裂构造共5条，其中已知F₁₀₀、F₁₀₁、F_h、F₂₀₁断层4条，据此修正了各断层的具体位置，尤其是F_h断层与F₂₀₁平推断层；另外，新推马路沟断层的一条NW向隐伏次级断层F₁₀₁₁，基本查明了各断层的位置及其平面分布特征。更多还原

【Abstract】 Based on the ground high-precision magnetic survey data,the research of the fault structure in the study area is explored in order to provide a basis for the subsequent geophysical exploration work to detect the deep development characteristics of fault structures,especially Malugou fault,and to improve the effect and benefit of geological exploration for uranium resources.According to the analysis ofΔT magnetic anomaly and magnetic field characteristics in the study area,combined with geology,magnetic parameters of rocks and distinguishing marks of magnetic anomaly of fault structure,there are interpreted for five fault structures.Four faults of F₁₀₀,F₁₀₁,F_hand F₂₀₁ are known,the specific position of each fault is corrected,especially F_h fault and F₂₀₁ shear-thrust fault.In addition,a NW-direction secondary buried fault F₁₀₁₁ of Malugou fault is newly introduced.The location and plane distribution characteristics of each fault are roughly found out.更多还原
