华北克拉通形成于太古代至早元古代,是世界上最古老的陆核之一。与全球多数克拉通不同的是,华北克拉通形成后,中生代以前一直保持稳定。但自中生代以来,特别是在燕山期,华北克拉通东部遭受了强烈的改造,其岩石圈被减薄,或被称为受到了“去根”作用。由于华北克拉通在全球克拉通中的特殊性,华北的岩石圈减薄问题得到了国内外学术界的广泛注意,对华北克拉通遭受破坏的动力学过程是近年来国 North China craton formed in the Archean to Early Proterozoic, is one of the oldest in the world. Unlike most caratons in the world, after the formation of the North China Craton, the Mesozoic has remained stable. However, since the Mesozoic, especially during the Yanshan Period, the eastern part of North China Craton has undergone a tremendous transformation and its lithosphere has been thinned, or it is said to have been “rooted.” Due to the particularity of North China craton in the global craton, the problem of lithospheric thinning in North China has drawn wide attention from academic circles both at home and abroad. The dynamics of the destruction of North China Craton in recent years
