现有文献多从下列两方面述及侵入岩体的水文地质意义:1)形成“阻水型蓄水构造”;2)形成“脉岩蓄水构造”。但瓦房复背斜中辉绿岩体的水文地质意义却不在于此,而是使其围岩形成不同的水文地质类型。一、区域水文地质概况瓦房复背斜位于半干燥的辽西中低山区,由蓟县系、寒武系、奥陶系组成,褶皱平缓,岩层倾角多在10～30度之间。辉绿岩沿背斜两翼及倾伏瑞裂隙侵入,向轴部延伸,展布于雾迷山组碳酸盐岩之中(图1),其产状可分为岩床、斜交岩脉(侵入
The existing literature more than from the following two aspects of intrusive rock hydrogeological significance: 1) the formation of “water-blocking reservoir structure”; 2) the formation of “pulse storage structure.” However, the hydrogeological significance of the diabase in the Wafang complex anticline does not lie in this, but forms different hydrogeological types in the surrounding rock. I. Overview of Regional Hydrogeology Wafang anticlough is located in the semi-dry low-lying mountainous area of western Liaoning and consists of Jixian, Cambrian and Ordovician facies with gentle folds and dip of more than 10-30 degrees. Diabase is intruded along the anticlinal wings and subducted fissures and extends to the shaft and distributes in the carbonate rocks of the Wumishan Formation (Figure 1). The occurrences of the diabase can be divided into sills and oblique veins Invaded
