摘要：

研究表明,不同类型岩石的形成导致不同类型元素的富集成矿,而后者与元素的自身结构密切相关:具惰性气体型离子结构的元素亲沉积岩,具过渡型或铜型离子结构的元素亲岩浆岩。进一步研究发现,陆壳大规模熔融固结,亦即花岗岩的形成过程,不但导致不同类型元素在上陆壳及其上层圈重新分配:亲氧(造岩)元素占据壳内熔融(岩浆)层的位置,亲硫(成矿)元素迁移到岩浆层上覆盖层且其中副族成矿元素按离子半径增大的顺序沉淀析出,亲水元素迁移到水圈而亲气元素则回归大气圈;同时揭示了与陆壳地质结构相适应的陆壳元素地球化学结构,体现了自然界微观和宏观的协调与和谐。

Abstract:

 Oreforming elements related to formation of different types of rocks are found with different kinds of ionic structures: those with the inertgaseous ionic structures generally enriched in the formation of sedimentary rocks, while those with the transitional or cupreous ionic structure are affinitive with the formation of magmatic rocks. Further researches indicate that various elements involved in the rock melting process are redistributed within and over the continental crust during the crystallization of crustal magma layer: the lithophile elements held the position of magma layer while the sulphophile elements moved to the cover of the layer, and the hydrophile elements migrated to hydrosphere while the atmophile elements to the atmosphere. Consistency of geological and geochemical structures of continental crust illustrated by the above processes reveals the unity between the microcosm and macrocosm of the natural world.

Key words:  granite, crustal melting, oreforming elements, ionic structure of element
