华北东部中生代构造格局转换过程中的深部作用与浅部响应

华北晚中生代构造岩浆岩带作为一个新的构造格局，以其鲜明的ＮＮＥ走向跨在古域不同的构造单元之上。在华北东部清楚地保留了标志早中生代格局转换过程的各种信息。本文所列举的晚三叠世超镁铁－－镁铁质和碱性侵入岩、堆晶岩、麻粒岩就是下地壳底部壳幔相互作用的产物；早－－中侏罗世的辉绿岩岩墙群、玄武岩粗岩系列的火山岩是中、上部地壳岩浆的表现，与此同时的受裂陷槽控制的含煤类磨拉石及火山磨拉石建造则是表的响应。由沉积

Deep Geological Process and Its Shallow Response during Mesozoic Transfer of Tectonic Frameworks in Eastern North China

As a new tectonic framework, the Late Mesozoic tectonic-magma belts in North China transverse in the NNE strike over different tectonic units of the Paleo-Asian domain with distinct characteristics. Much information marking the Early Mesozoic transfer of the tectonic frameworks can be found in eastern North China. The information is expounded in the paper: Late Triassic mafic-ultramafic and alkaline intrusives, cumulate and granulite are products of crust-mantle interaction in the lowermost of the continental crust; Early-Middle Jurassic diabase dyke swarms, basalts and latite reflect magmatisms in the upper-middle crust; coal-bearing quasi-molasse and volcano-molasse formation controlled by the fault basins formed in J1-2 are responses of the surface to the deep geological process. The new ENE-trending framework marked by sedimentary-tectonic-magmatic belts is controlled by neogenic and inherited tectonic factors. In summary, an idea is proposed that the deep geological process dominates the transfer of different tectonic frameworks, and deformation and formation of the surface are its responses.
