中原生代的一般特征中原生代包括表壳岩和深成岩,它们形成于基诺兰地壳变动之后或在它的末期,一直到2000—1900百万年前卡累利阿地壳运动结束才完成,因此这个代约800百万年。存加拿大称阿费布,澳大利亚称努拉津。世界范围成型为卡累利阿超群。主要沉积建造类型有地台型、冒地槽型和优地槽型。以地台型和冒地槽型发育最广。 The Mesozoic general characteristics of the Mesozoic Mesozoic include the crustal rocks and plutons, which formed after the kelorean crustal movement or at the end of the crust, until 2000-1900 million years before the end of Karelia crust movement completed, so this generation About 800 million years. Save Canada called Afib, Australia said Nurazin. Molding world-class Karelia. The main types of sedimentary construction platform type, runoff trough type and excellent groove type. To platform type and run-off trough the most widely developed.
