中文摘要:本文论述了地洼区喀斯特洞穴的发育,成矿和演化规律。比较了地槽、地台和地洼三个大地构造单元区喀斯特洞穴之差异,揭示洞穴发育与大地构造之间的内在联系。根据地洼区洞穴发展,划分了五个成洞期。并对地洼区洞穴溶蚀堆积特征及矿床特征和分类做了讨论。又从地洼区地壳运动特点、古地貌演化、岩性条件以及古水文、古气候变迁,论述了地洼区洞穴时空发展不平衡的发育规律。最后指出了地洼区洞穴研究在科学和生产上的实际意义。

Abstract:This paper deals with the development features, mineralization and develo-pment regularities of karst caves in diwas, compares the karst caves in threetectonic units--geosynclines, platforms and diwas, and reveals the inner relationbetween cave development and tectonics. The cave development in diwas involves five cave-forming phases. This paperdiscusses the features of cave corrosion and deposition as well as the features andclassification of mineral deposits. From the features of crustal movements, paleo-morphological evolution, lithological conditions and paleohydrological and paleocli-matic migration, the paper discusses the imbalance of temporal-spatial develo-pment of caves in diwas. Finally the paper points out the actual significance ofthe cave study in diwas for science and production.
