摘　　要：中国特大型金属矿床成矿偏在性主要表现为对矿种、矿床类型、成矿时间和成矿背景的特殊选择，而且主要取决于地质、地球化学和地球物理多种成矿控制因素非常罕见的耦合汇聚，称之为异常成矿构造聚敛场。据国内主要特大型矿床的研究，随地质历史演化初步可划分：太古宙—古元古代同剪切异常成矿构造聚敛场、元古宙—古生代三同一体异常成矿构造聚敛场、中生代“行”、“列”、“汇”构造－岩浆异常成矿构造聚敛场、新生代多阶湖汇流异常成矿构造聚敛场。Metallogenic preferentiality of giant metallic deposits of China mainly finds expression in their special selectivity towards specific ore forming metals,deposit type,and ore forming time and background,and depends chiefly upon coincident associations or couplings of geological,geochemical and geophysical ore controlling factors.Such associations or couplings are called exceptional metallotect convergences,which can be divided into Archean Paleoprolerozoic syn shearing exceptional metallotect convergence site,Proterozoic paleozoic trinity exceptional metallotect convergence site,Mesozoic “row line cluster” magmatic exceptional metallotect convergence site and Cenozoic multi level lake confluence exceptional metallotect convergence site.Each “convergence site” corresponds in time domain to an superlarge deposit whose ore forming metals and deposit type are typically controlled by the convergence site.
