湘中“桃江式”锰矿含锰岩系的定量研究及其找矿意义

本文从分析地质体数学特征的思想出发,来研究“桃江式”锰矿的含矿母岩－“含锰岩系”的数学特征。含锰岩系主要由五种岩石组成：粘土岩、黑色页岩、条带状页岩、含锰灰岩和碳酸锰矿层,其数学特征研究包括其统计特征分析、结构特征分析和空间特征分析。文最后讨论了这些数学特征在寻找同类锰矿中的意义。

THE QUANTITATIVE ASSESSMENTS OF MANGANIFEROUS ROCK SERIES OF "TAOJIANG TYPE" MANGANESE ORE AND ITS PROSPECTING IMPLICATIONS IN THE CENTRAL REGION OF HUNAN PROVINCE

This paper is based on ''the theories of the Mathematical characters For Geological Objects''analysing the mathematical characters of ore-bearing mother rocks of ''Tao jiang Type'' manganese deposit and manganiferous rock series which consists of five rock types,i. e. black shale,banding shale, clayrock, manganiferous limestone and carbonate manganese ore bed. The mathematical characters include statistical characters, structure characters, spatial characters.At first,the statistical characters mainly state the distributive types and the sieving characters of complex distributions of manganese values and associated component values in manganiferous rock series and their genetic implications.Secondly, the structure characters give the relative links and the clustered characters of manganese element and associated components, and indicate their lithogenetic implication;thirdly,spatial characters are based on the theories of Markov processes in stochastic process analysing the time-space laws of manganiferous rock series and including the studies of the transition probability of five rock types,the studies of sedimentary cycle type and the analysis of sedimentary environments.Finally, the paper discusses the potential implications of these mathematical characters in prospecting for"Taojiang Type" manganese deposits.
