摘　　要：建立各种地质模型是对内生金属矿床进行深部成矿预测的主要途径和重要方法．分别论述了构造控矿模型、矿化有序分布模型、工业矿体产状模型、矿床（体）空间展布模型及成矿作用动力学模型的主要内容和一般规律，并讨论了其应用的途径和方法．Studying and constructing geological models is an efficient way and important means of metallogenic prognosis in the depth.These geological models include structural ore conrol model,orderly distribution model of mineralization,occurrence model of ore body,distribution model of deposits (ore bodies) and dynamic model of endogenic ore formation. When constructing the structural ore control model,we must identify the structural type,style,and the regularities of controlling to the activation,migration, mineralization scale and mineralization degree.Furthermore,the favourable structures and places are to be verified.The relationship between structural evolution and metallogenic evolution is also stated in detail.When constructing the orderly distribution model of mineralization,the spatial distribution characteristics of mineralization type must be verified first.Secondly,we must learn the relation between the orderly distribution of alternation and the mineralization degree as well mineralization scale.Thirdly,we must abstract the microscopic information on mineralization from trace elements.Last,the regular change of physical chemical parameter usually shows the local concentration of mineralization and ore body occurrence. Studying metallogenic dynamic model may reveal the mechanism of mineralizational concentration and show us evidence of deep metallogenesis.
