千佛山与趵突泉泉水形成关系研究

Research on Relationship between the Formation of the Baotu Spring and Qianfo Mountain

摘要:

从沉积盖层的形成、岩浆的侵入、碳酸盐岩岩溶发育过程及演化、构造运动对盖层的切割与破坏及对地形地貌的塑造等方面，分析了济南千佛山、佛慧山和以趵突泉为代表的济南四大泉群的内在联系。研究表明，燕山运动末期奠定了济南构造全貌，新近纪末期，千佛山、佛慧山一带基本形成了与现在相近的地貌特征，市区一带，在趵突泉、黑虎泉泉群附近形成了“天窗”。千佛山、佛慧山一带是趵突泉泉水的重要补给区，碳酸盐岩在市区隐伏于地下，是三水转化系统的重要介质，在地形低洼、构造有利的部位趵突泉腾空而出，其出流时间大约在距今1万至6000a之间。

Abstract:

In this paper, through analysis on the formation of sedimentary covers，magmatic intrusion， development process and evolution of carbonate rocks, cutting and destroying to the cover layers and the formation of landscapes caused by tectonic movement, internal connection of four springs represented by Qianfo Moutain, Fohui Moutain and Baotu Spring has been analyzed. It is showed that late Yanshan movement has established the structures of Jinan city, and geomorphic characteristics are similar to now in Qianfo Moutain, Fohui Moutain area were formed in late Neogene, and in the urban areas, roof window came into being around Baotu Springs and Heihu springs. Qianfo Moutain and Fohui Moutain area are important recharge area of Baotu Spring. Carbonate rocks are hidden in the urban underground, which are important mediators of three types of water transformation system. In low-lying terrain and favorable position of tectonics, Baotu spring start gushing out at about ten thousand years to six thousand years ago.
