山东省花岗岩的成因分类刍议

HUMBLE OPINION ON THE GENETIC CLASSIFICATION OF GRANITOIDS IN SHANDONG PROVINCE

摘要:

根据地质构造背景、形成机制、物质来源、岩石共生组合,岩体地质、岩石学、矿物学、地球化学和同位素地球化学特征,将山东花岗岩划分为四个成因系列、十个成因类型。即:Ⅰ.前寒武纪地壳改造系列;Ⅰ.1.原地交代型;Ⅰ.2.异地深熔型;Ⅰ.3.大陆板块碰撞型;Ⅰ.4.高级变质型;Ⅱ.同熔系列;Ⅱ.1.结晶分异型;Ⅱ.2.岩浆混合型;Ⅲ.碱性系列;Ⅲ.1.结晶分异型;Ⅲ.2.下部地壳重熔型;Ⅳ.幔源系列;Ⅳ.1.结晶分异型;Ⅳ.2.分熔型。原地交代型按其被改造原岩的性质,可划分为正变质和副变质亚型。

Abstract:

In terms of tectonic environment, formation mechanisms, material sources, paragenetic rock association, as well as its geological, petrological, mineralogical, geochemical and isotopic characteristics, the granitoids in Shandong Province can be divided into four genetic series and ten genetic types, they arc: Ⅰ. Precambrian crust transformation series, including Ⅰ_1. autochthonous replacement type; Ⅰ_2. anatectic type; Ⅰ_3. continental collision type; Ⅰ_4. highgrade metamorphic type; Ⅱ. syntectic seriers, i...
