区域地质概况本区位于下扬子拗陷东端,溧水-宁芜中断凹东缘,茅山断凸西侧.区域中部广泛分布着受区域性深断裂控制的燕山旋回的火山-侵入杂岩,构成北北东及近东西向的构造岩浆杂岩带. 区内经历了印支期、燕山期、喜山期的多旋回构造运动(印支前为升降运动),构造活动具有明显的继承性. 在印支旋回及燕山旋回早期,它和宁芜处于
Regional Geological Survey The area is located at the eastern end of the Lower Yangtze block, the eastern margin of the Lishui-Ningwu discontinuity and the west of the Maoshan Sag.The volcanic-intrusive complex of the Yanshan Cycle controlled by the regional deep-fault control is widely distributed in the central part of the area, North-north east and near-east-west tectonomagmatic complex zone.The polycyclic tectonic movement in Indosinian, Yanshanian and Himalayan period (uplift movement before Indosinian) experienced significant succession in tectonic activity. In the early Indosinian and Yanshan cycles, it was located in Ningwu
