基本层序界面类型及其在岩石地层单位划分中的应用
Essential sequence boundary and its application to lithostratigraphic divi- sion
摘要
Abstract
The essential sequence boundary is a major transformation in the vertical plane. It can be divided in downward succession into three groups, i.e., cycle/non-cycle essential sequence boundary (level Ⅰinterface), cycle/rhythmic essential sequence boundary (levelⅡinterface) and fining-upward graded/coarsening-upward graded essential sequence (level Ⅲinterface). These interfaces are widely developed in clastic sedimentary rocks, and hence are important boundaries for subdividing geological mapping unit in detail. This unit is an important complement for traditional layering of sedimentary sequence and interface choosing for geological mapping unit. More importantly, it is a guide to the division of geological mapping unit, the analysis of sedimentary facies and the study of re⁃gional geology for particularly thick clastic units in the orogenic belt.关键词
