摘要
成矿模式是对矿床赋存的地质环境、内外部特征、控矿因素、矿化的时空演化规律、矿化标志、成矿物质来源、成因机理和找矿标志的高度综合描述和解释,将复杂多变的成矿作用和地质现象上升为成矿学的地质理论,并用文字、图表予以表达,使人们对同类或一组相似矿床的成矿特征有一个完整的概念,从整体上深化对矿床的认识。按成矿单元的差异和勘查要求,将成矿模式分为区域的、矿床的成矿模式和找矿模型三部分。并列出了建立各类模式(型)的具体内容。
The minerogenetic model generally refers to summarizing the geologicalsetting, evolutionary process and genetic mechanism from the four-dimensionalspace for the formation of a mineral deposit. It can fully roflect the complexgeological conditions for mineral deposit formation and the process of mineraliza-tion and indicate the paragenetic relationship and mutual restriction of differentmineral commodities and different types of mineral daposit under the same geo-logical conditions. The minerogenetic model can take hold of a group of mineralprospecting indications of the same type of mineral deposit, which may be usedto set up a mineral prospecting model and guide the prognosis of mineralresources and geological exploration. The minerogenetic model may be divided into three parts: the regional min-erogenetic model, mierogenetic model of mineral deposit and mineral prospectingmodel. The regional minerogenetic model aims to show the features of distributionof various solid mineral commodities in a particular minerogenetic unit, expoundthe temporal-spatial evolution of mineralization, genetic relation and mineroge-netic mechanisms within a minerogenetic unit of a certain class, make masterlyand well-grounded generalization and summation of regional minerogenetic regu- larities, upgrade the research a regional minerogenetic theory and guide the prog-nosis and exploraton of regional mineral resources. The mineral deposit modelaims to describe the process of formation of a mineral deposit, various minerali-zation features (including geological, geophysical, geochemical and remotesensinggeological features) and summarize and interpret the genetic mechanism andother essential factors of a mineral deposit. It expresses the results of the currentstudy of minerogenetic theory. But the contents of the summary neither indicatethe essential factors and the methods or means for looking for and finding min-eral deposits nor provide direct or indirect information for mineral prospecting,and it is difficult to show the the entire process of finding a mineral depositand the optimal way to find a mineral deposit by geological means; thereforethe mineral prospecting model is a method or tneans to summarize the geologicalfactors of prespecting for a concrete mineral deposit. In the paper the concrete contents of the three models are listed.The minero-genetic model is a big subject in the current study of the theories of mineral de-posits and a component part of the theory of mineral deposit formation. It hasfar-reaching influence and import significance for the study of theories on min-eral deposit formation, prediction of mineral resources and mineral exploration.
