Occurrence Characteristics of Groundwater in the Low Mountain and Hilly Areas of Magmatic Rocks in the Southern Mountainous Area of Central and Southern Shandong Province

摘要:

岩浆岩低山丘陵区地形地貌及地质条件复杂，地下水蓄存环境差，水资源贫乏，水文地质研究程度低，长期以来一直存在极大的找水困难。通过开展典型地区水文地质调查与找水打井示范，深化了对地下水赋存和补径排条件的认识，地下水赋存空间在垂向上可分为浅部风化裂隙带和中深部岩脉裂隙网络，平面上分为断裂构造裂隙带、岩脉裂隙带和岩性接触裂隙带，总体呈现“两层三带”基本特征；为寻找赋水打井目标、有针对性布置勘查工作提供了参考，提高了找水效果。

Abstract:

The topography, geomorphology and geological conditions of magmatic hilly area are complex. The groundwater storage environment is poor. The water resources are poor, and the degree of hydrogeological research is low. There has been a great difficulty in finding water for a long time. Through hydrogeological survey and the demonstration of searching for water and drilling wells in typical areas, the understanding of groundwater occurrence and filling and drainage conditions has been deepened. The groundwater occurrence space can be divided into shallow weathered fracture zone and middle-deep dike fracture network vertically, and divided into fault structural fracture zone, dike fracture zone and lithologic contact fracture zone horizontally. Basic characteristics is shown as "two layers and three zones". It will point out the direction for finding the target of water well drilling and arranging the exploration work accordingly. It also will improve water finding effect.
