摘要: 秦岭是我国南北方之间重要的自然分界线。对秦岭山地岩溶地貌发育规律的研究,将有助于我国南北方岩溶化作用过程的对比。1981年夏季,笔者在秦岭北部辋川山区发现了锡水洞旧石器时代早期古人类文化遗址,结合该遗址的综合研究,进行了岩溶地貌的野外考察工作[1]。这里仅就该区岩溶洞穴的成层性及其与活动性断裂构造的关系作初步探讨。

Abstract: In this paper,the fundamental law of the karst caves formed in Wangchuan, the north Qinling Mountains is discussed.In Wangchun region NE and NW direction shearing fractures combining with EW direction main fault formed a neotectonic fracture system which is still moving,and it controls the level extending direction of the karst caves.The level caves on three different elevations at slope reflect the intermittent rise of crust and karstification.stages.Therefor,the level caves can compare with the three level erosion surfaces in the Qinling Mountains.This provids important evidences for the comparison of the karstification periods between the South and the North in the Cenozoic.
