| 摘 要： | 地质构造、气候、水动力条件对鲁中南地区丰富多彩的岩溶形成起着控制作用。下古生界特别是中寒武统上部及中、下奥陶统的碳酸盐岩是该区岩溶发育的基础,新生代继续活动的断裂构造把被非可溶岩分割的碳酸盐岩岩层串通成统一的水文系统。新生代多期的上升运动,使该区持续保持较大的地形高差和积极的水文交替条件,特别是该区的泰山、鲁山、沂山、蒙山等均由前寒武系变质岩及岩浆岩组成,它们在新生代的漫长地质历史时期,直至今日均高于周围的可溶岩分布区,造成了该区岩溶发育可经常受到强大的外源水影响的基本格局。

| Abstract: | Geological structure, climate, hydro-dynamic conditions will control the formation of karst in middle and south part of Shandong province. Carbonate rocks in lower Paleozoic, in particular in the upper Cambrian and the lower Ordovicianare the basis for karst development. Faults which continues its activities in Cenozoic combined carbonate rock which were seperated by non-carbonate rock as an integrated hydrological system. Multi-phases uplifting movements in Cenozoic can maintain a larger area of terrain elevation and positive turn of hydrological conditions, especially Taishan mountain, Lushan mountain, Yishan mountain, Mengshan mountain are all composed of Precambrian metamorphic rocks and magmatic rocks. They have been higher than the surrounding karst rock area in a long history, which has caused the basic structure that karst development will influenced by strong allogenic water. |
