文章讨论了对流地幔向大陆的输入是大陆成矿作用的直接驱动力。以华北燕山造山带为例,认为卷入的对流地幔可能深达670km界面。对流地幔的热和物质输入大陆诱发形成一个新的被扰乱的岩石圈–软流圈系统(LAS),它成为大陆成矿作用的重要深部环境。提出了被扰乱的大陆岩石圈–软流圈系统及其成矿作用的4个类型:①伸展环境下的岩石圈巨大减薄作用;②挤压环境下的岩石圈巨大减薄作用;③挤压环境下的岩石圈巨大加厚作用;④太古克拉通岩石圈根在造陆运动中,地幔深部小的热扰乱。最后讨论了大陆成矿作用的基本过程。
The paper discusses the input of the convective mantle into the continent as a direct driving force of the continental mineralization. Taking the North China Yanshan orogenic belt as an example, the convective mantle may be as deep as 670 km. The convection of the mantle of heat and matter into the mainland induced the formation of a new disturbed lithosphere-asthenosphere system (LAS), which became an important deep-sea mineralization in the mainland. The disturbed continental lithosphere-asthenosphere system and its metallogenic processes are presented in four types: (1) the great thinning of the lithosphere in the extensional environment; (2) the great thinning of the lithosphere in the compression environment; Under the pressure environment, the lithosphere has a great thickening effect; ④ The Swakopmund lithospheric root is making land movement and the small heat in the deep mantle disrupts it. Finally, the basic process of continental mineralization is discussed.
