摘　　要：利用岩石密度差异、磁性变化情况研究渭河盆地的一级断裂与二级断裂,分析了渭河盆地的三个重力异常带,异常带亦是主控断裂带,划分了盆地构造单元。Based on the density differences of rocks,magnetic variation and the three gravity anomalies,researches on the primary and secondary faults occurring in the Weihe Basin have been made,showing the anomaly zones are the major fault zones,from which the Weihe basin can be divided into different tectonic units.

关 键 词：渭河盆地 重磁场特征 布格异常 梯度模量 断裂划分
