中国生物礁时空分布特征及其地质意义

中国生物礁从震旦纪至新近纪均有发育，分布范围广，并有泥盆纪、二叠纪和新近纪3个主要造礁期。不同地史时期造礁生物及其附礁生物的组合不同，形成的礁体具有不同的类型、规模和特征。生物礁的发育受构造作用、海平面变化及古地理环境控制，同时也受遣礁生物兴衰演化的控制。生物礁与油气藏、金属矿床空间上关系密切，成因上可有联系。笔者系统总结了20多年来中国生物礁的研究进展和成果，并指出利用多学科综合方法能较成功地预测隐伏生物礁的发育和分布，寻找礁型油气藏和礁型矿床。

Characteristics of spatiotemporal distributions of reefs in China and their geological significance

The reefs widely developed from Sinian to Neogene in China, with main reef-forming stages in Devonian, Permian and Neogene, respectively. The combinatorial types of reef-forming organisms and reef-inserted organisms were fairly different during different geological periods, and the reefs varied respectively in type, size and feature. The development of reefs was controlled by the tectonic setting, sea-level movement, paleogeographic environment and evolution of reef-forming organisms. The reefs are closely related to oil and gas reservoirs and metal deposits in spacial distribution, which can be considered that they might have genetic relations with each other. The authors summarized the progress in the research of the reefs in China over the last 20 years, and proposed that using integrative methods can forecast successfully the development and distributions, ofthe perdu reefs, so as to search out the reef-type oil and gas reservoirs and metal deposits.
