摘要: 中始新统温州组下部发育的海相生物碎屑灰岩在台北坳陷内分布广泛,为热带、亚热带潮湿气候条件下的浅海陆棚沉积.岩石中生物发育,既是地层对比的标志,又是有利的生油岩、储集岩.它是台北坳陷寻找工业油气的有利目的层.

Abstract: Marine bioclastic limestone in the lower part of WenZhou formation,middle Eocene,iswidely spreaded in the TaiBei depression.This is a neritic platform deposition under asubtropical humid climate.Organisms are well developed in these rock formations which canbe served as markers in formation correlation.Moreover,they are favorable source rocks as well as reservoir rocks.They are favorable targets in the exploration of commercial oil and gaseposits in the TaiBei Depression.
