渭北煤田下古生界灰岩的岩溶发育和含水介质特征

FEATURES OF KARST DEVELOPMENT AND AQUEOUS MEDIUM OF LIMESTONE OF LOWER PALAEOZOIC GROUP IN WEIBEI COAL FIELD

本文将渭北煤田下古生界灰岩的地下溶洞按其沉积物的时代划分为两个古岩溶期。在新构造运动影响下,结合渭河地堑的形成过程,指出第二期古岩溶带的形成;进而指出在近期新构造运动影响下,已形成的第二期古岩溶带位置的重新分布及对不同构造部位灰岩含水介质的影响。

According to the times of the sediment, the underground karst caves of limestone of Lower Palaeozoic Group in Weibei Coal Field are divided into two ancient karst stages. Under the influence of the new structure movement, combined with the formation process of Wei River graben, the formation of the second time is pointed out and then under the influence of the recent new structure movement, the effect of the redistribution of the ancient karst solution zone formed in second time on the aqueous medium of limestone in different structure position is also shown in the paper.
