广西泥盆系广泛分布,赋存有大量的有色金属矿产。在前人研究过的典型地层剖面上,我们根据不同的目的,选择了三类剖面(区域背景剖面、矿区剖面和含矿层位剖面)研究了1450个样品,对该区的成矿元素分布、富集规律和地层对成矿的控制作用取得了新的认识。各剖面研究序列,自经相关系数、滞后之间的关系以及趋势因子tix的第一自相关系数P_1与转移矩阵U的最大实数特征值λ_1的吻合程度检验表明,所采样品具有马尔科夫性质,代表性强,用来描述整个沉积程过程特征能保证过程的连续性。
Devonian Guangxi is widely distributed, there is a large number of non-ferrous metal deposits. In the typical stratigraphic section studied by predecessors, we selected three kinds of sections (regional background section, ore section and ore-bearing layer section) to study 1450 samples according to different purposes, and analyzed the ore-forming element distribution, Enrichment law and formation control of mineralization has gained new understanding. The correlation between the correlation coefficient and hysteresis and the correlation between the first autocorrelation coefficient P_1 of the trend factor tix and the largest real eigenvalue λ_1 of the transition matrix U indicate that the sampled samples have Markov properties , Representative, used to describe the process characteristics of the entire deposition process to ensure the continuity of the process.
