In order to study on tectonic evolutionary characteristics of Laiwu basin and its influence on the hydrogeological characteristics. Using the structural balanced profile principle combine with existing data calculate the rate of basin extension and the main fracture activity rate in Laiwu basin. And then, restore the the history of tectonic evolution. Using 96drills and drinking wells’survey data, karst groundwater system can be classified into two types: bedding type, inversion type. The propeties of these types are compared and analyzed in structural position, aquifer types, karst groundwater recharge and drainage conditions and hydrochemical characteristics. Analyze two karst groundater concentration zones’hydrogeological characteristics by influence of magma intrusion in the Stage of Yanshan through field geological survey. Drilling results shows that semi consolidated sands and conglomerates in Paleogene strata is developed in some areas of Laiwu basin, the acquifer is watery, and has characteristics of pore water and fractured water.
