华北地块为兴凯构造运动古中国地块解体形成,震旦纪至三叠纪,经历了漫长的相对稳定时期,主要表现为地块整体的升降运动,地层岩相稳定,厚度变化不大,地层之间一般为整合或平行不整合接触,岩浆活动不发育。中、新生代时期,华北地块受断裂控制,逐渐解体为规模不等的断块,经历了复杂的褶皱、断裂变动,岩浆活动频繁而强烈。对华北地块破裂过程及构造活动规律的研究,在阐明矿产的形成、地壳演化发展规律方 The North China block is the Xingkai tectonic movement. The ancient Chinese block was dissolved and formed from Sinian to Triassic. It experienced a relatively long period of relative stability. It mainly manifested as an overall uplifting movement of the block, with stable lithofacies and little change in thickness Generally, the strata are either integrated or parallel unconformity and magmatism is not well developed. During the Meso-Cenozoic period, the North China block was controlled by faults and gradually disintegrated into blocks of different sizes, which experienced complicated folds and faults. Magmatic activity was frequent and intense. The research on the rupture process and tectonic activity of North China block illustrates the formation of the mineral and the evolution of the crust
