中国北方寒武—奥陶系岩溶层组类型及其区域变化规律

KARST STRATA ASSOCIATION TYPES OF THE CAMBRIAN-ORDOVICIAN IN NORTH CHINA AND REGULARITY OF THEIR REGIONAL VARIATION

本文在大量剖面资料统计的基础上,根据岩层的厚度比例和连续厚度及其组合形式,对我国北方寒武—奥陶系岩溶层组类型进行了划分,着重论述了岩溶层组类型的区域变化规律。为含水层系统的划分和水资源评价及区域岩溶发育规律的研究,提供了重要的基础资料。

The paper makes a division of the karst strata associations types of the Cambrian- Ordovician in north China and exposition of regularity of their regional variation, on the basis of a vast amount of sectional statistical data. The division based on the rate of thickness, succesive thickness and association form of carbonate and non - carbonate strata, is of practical significance for understanding the situation of aquifer and impermeable layer of region, and that based on the rate of thickness, succesive thickness and association form of limestone and dolomite is of practical significance for dividing aquifer group of karstic water system. The regularity of regional variation of the karst strata association types will suggest important basic data for study on karst developmental law of this region. Authors:WengJintao HeShiyi
