【摘要】：基于徐州城市地质调查与徐州地区岩溶塌陷调查的平台,紧扣徐州岩溶地质特征和徐州城市建设对岩溶地质调查的需求,以查明城市规划区岩溶发育特征为目标,在充分利用前人资料的基础上,分别针对裸露型岩溶区和覆盖型岩溶区展开地质调查,并辅以物探及钻探等进行勘察验证,有力地提高了区内岩溶地质调查成果的精度。同时,对徐州城市规划区岩溶层组、岩溶出露条件以及发育程度等进行了分析,区内岩溶发育主要为新生代以来的浅表性岩溶,岩溶发育程度总体受构造控制呈北东向"强-弱"相间展布,废黄河断裂带沿线,奥陶系马家沟组和寒武系张夏组碳酸盐岩分布区岩溶极为发育。
[Abstract]:Based on the platform of Xuzhou urban geological survey and Xuzhou karst collapse survey, the karst geological characteristics of Xuzhou and the requirements of Xuzhou urban construction for karst geological survey are closely related, and the aim is to find out the karst development characteristics in the urban planning area. On the basis of making full use of the previous data, the geological investigation was carried out for the bare karst area and the overlying karst area respectively, and was verified by geophysical exploration and drilling. The precision of the karst geological survey results in the area was improved powerfully. At the same time, the karst formation, outburst condition and development degree of karst in Xuzhou urban planning area are analyzed. The karst development in this area is mainly superficial karst since Cenozoic. The karst development degree is generally controlled by the structure and distributes in the north east direction "strong-weak" phase, along the abandoned Yellow River fault zone, the karst is extremely developed in the carbonate rock distribution area of the Ordovician Majiagou formation and Cambrian Zhangxia formation.
