| 摘 要： | 根据野外实测剖面分析刘家场地区奥陶系从西陵峡组到临湘组的地层特征、古生物类型和沉积相演化规律，表明该区奥陶系以碳酸盐岩台地相序为主，主要由局限台地、开阔台地、台地边缘生物礁和沉没台地组成。在此基础上，运用马尔科夫链随机过程建立研究区沉积序列概率模式。以定量的数学地质方法估计了岩相在垂直剖面上的转移概率，克服了传统的定性沉积相模式建立方法中存在的由人为因素导致的差异，研究结果表明这是一种行之有效的将复杂地质问题简化的处理方法。

| Abstract: | Based on the stratigraphy section measured and observed in Liujiachang, the stratigraphy characteristic, paleontological type and the facies evolution law from Xilingxia Formation to Linxiang Formation were analyzed. It showed that the face of Ordovician was carbonate platform and it mainly included restricted platform, open platform, organic reef in platform margins and submerged platform. On the above basis, the authors used the Markov chain random process and established the probability patterns of sedimentary sequence in the study area, estimated the lithofacies transition probability in the stratigraphy vertical section overcome the differences caused by human reason in a qualitative facies modeling method by use of quantitative mathematical method. The results showed that the Markov chain random process was an effective method to simplify the complex geological problems |
