摘　　要：根据西成矿田中泥盆统安家岔组和西汉水组具有多旋回性的特点，运用马尔科夫链分析法对其进行沉积相的划分，总结出中泥盆世处于海洋环境，并可划分为４个相带：陆缘碎屑岩相带、碳酸盐台地相带、台地边缘相带及浅海陆棚碎屑岩相带，进一步分为１１个相和２２个亚相。On the basis of the middle Devonian(Anjiacha and Xihanshui formations ) in Xicheng orefield possess multicycle feature, authors in this paper put to use of the Markov Chain method to analyse the sedimentary facies and conclude that the middle Devonian epoch was in ocean environment and there are four facies belts in it, viz, epicontinental clastic facies,car-bonate platform facies , platform edge facies and neritic shelf clastic facies,and go further to divide it into 11 facies and 22 subacies.
