FEATURES AND FORMATION MECHANISM OF SUBAQUEOUS DIKE SWARMS IN GUANGXI

Publish Date: 15 November 1995

摘要: 近年来，广西桂林、南丹、凌云、乐业等碳酸盐台地发现一批水下沉积岩脉群。岩脉群充填于中晚泥盆世和晚石炭世地层中，岩脉时代为早二叠世和早三叠世，岩性为角砾状灰岩和灰岩。岩脉的出现与晚古生代地台的分裂解体有密切关系，为研究古构造环境提供了宝贵资料。

Abstract: In recent years a group of subaqueous dike swarms have been found in carbonate platformsin Guilin,Nandan ,Lingyun and Leye,Guangxi.Dike swarms are injected into Mid-Late Devoni-an and Late Carboniferous strata;their ages are Early Permian and Early Triassic;their litholo-gies are represented by brecciated limestone and limestone. The appearance of dikes were close-ly related to the break-up of the Late Paleozoic platform.
