造盆作用及成矿盆地的历史——动力综合分类建议

HISTORICAL-DYNAMIC INTEGRATIVE CLASSIFICATION OF BASINOGENESIS AND ORE-FORMING BASINS

本文把历史分析方法与动力分析方法两种分折方法结合起来,提出了一个综合的盆地分类方案。按历史动力综合分类,造盆作用及盆地可划分为三大类:大洋壳型、雏陆壳(过渡壳)型及大陆壳型大壳型中可细分为活动区型及稳定区型。雏陆壳型包括前地槽型及地槽前期型。大陆壳型中计有地槽后期型、地台型和地洼型。

Interesting classifications of basinogenesis and basins have been proposed by many scientists. They classify basinogenesis and basins mainiy from a single angle, either from a historical angle of from a dynamic angle. In order to more comprehensively understand them for more effectively guiding prospecting and exploration, the author integrates the two methods of analysis with each other and proposes an integrative classification. According to the historical - dynamic integrative classification, basinogenesis and basins can be divided into three types oceanic crust type,embryo-continental (transitional) crust type and continental crust type. Oceanic crust type can be subdivided into mobile region type (mainly tensional) and stable ragion type. Embryo-continental type includes pre-geosynclinal type (divisible into several mobiie region types and stable region types with tensional type predoninating among mobiie regin types) and early-geosynclinal type (mainly tensional) . Continental crust type includes late - geosynclinal (fold beit) type (compressional or tensional), platform type (mainly sinking and rarely tensional subsidence - aulacogen) and geodepression (diwa) type (compressional. tensionai or compressional - tensional) .
