使用计算机对下塔尔克乌砂岩组中浊积岩(罗马尼亚东喀尔巴阡山)的马尔科夫链分析

如复理石沉积那样的垂向连续型韵律序列的研究能揭示有关生成过程和沉积区域的重要信息。无论不同岩性的垂向组合是否随机的，甚至没有沉积层序的优选次序，也能进行马尔科夫链分析这样的统计分析。此类分析适用于下塔尔克乌砂岩组（罗马尼亚东喀尔巴吁山）的复理石沉积，注意这些沉积物保存的发生程序并给以储存，而那些沉积物（至少被研究的层段）是浊流作用的产物，这些浊积物堆积在水道化沉积亚环境（诸如水道化的中深海扇之类）具良好分带的沉积区中。

APPLICATION OF MARKOV CHAIN ANALYSES USING COMPUTER IN TURBIDITES OF LOWER TARCAU SANDSTONE FORMATION(EAST CARPATHIAN MOUNTAINS,ROMANIA)

Study of the vertical succeeding type of the rhythmic sequences such as flysch deposits canoffer interesting informations concerning the generating processes and the depositional areas.Statistical analysis,such as Markov chains analyses,can establish if the different lithologies vertical association is random or not and, if not,which is the sedimentary sequences preferentialorder. This type of .analysis was applied to the flysch deposits from the Lower Tarcau SandstoneFormation (East Carpathian Mountains, Romania), which were observed on the presence of agenerating process with a memory and thus these deposits,at least for the studied interval,arethe products of turbiditic processes accumulated in a sedimentary area with good zonation of depositional subenvironments such as channeled middle deep-sea fan
