一湖南宁远早—中泥盆世陆源碎屑岩地层剖面,位于湖南省南部宁远县半山水库(以下简称半山剖面),厚471.03米,其岩性主要是一套紫红色砂岩、泥质粉砂岩,含植物化石碎片,上部含多层豆状赤铁矿,下部遗迹化石和各种类型的交错危理发育。虽然借助野外的宏观标志和室内分析,某些层位的岩相类型可以比较准确地确定,但对整个剖面在岩相类型和旋回特征上的纵向演化系列很难把握。本文试图用马尔科夫概型分析,以剖面时间序列内部结
A Ningyuan early-mid-Devonian terrigenous clastic stratigraphic section of Hunan Province, located in the semi-mountain reservoir of Ningyuan County in the south of Hunan Province (hereinafter referred to as the Mid-level section), is 471.03 meters thick. Its lithology is mainly composed of purplish red sandstone and argillaceous siltstone , Containing fragments of plant fossils, multi-layered hematite in the upper part, fossils in the lower part, and various types of staggered crises. Although the lithofacies types of some strata can be determined more accurately with the aid of the macro sign and field analysis in the field, it is very difficult to grasp the series of longitudinal evolution of lithofacies types and cycles in the whole profile. This article attempts to use Markov-type probabilistic analysis to profile the time series of internal junctions
