摘要
等时性地层界面是组成沉积盆地成因地层格架的主要构件之一。按其成因不同可划分为4类;侵蚀不整合面、无沉积的间断面、火山活动标记面和相转换面。正确地鉴别地层界面的性质和成因,对成因地层对比和建立盆地成因地层格架都有十分重要的意义。
Chronostratigraphic interface is an important component of the genetic strati-graphic framework of a sedimentary basin. Four types may be subdivided according to the origins: tectono-erosional unconformities, non-depositional hiatus, marker horizons of volcan-ism, and transformation interface of facies. It is important to recognize correctively the properties and origins of chronostratigraphic interface for the reconstruction of the genetic strati-graphic framework and the study of the evolution of sedimentary basins.
