Recent studies suggest that the Mesozoic granitoids and the contemporary mafic and ultra-mafic rocks from the North China block and Dabie-Sulu orogenic belt have the similar Sr, Nd isotopic characteristics, and many of the granitoids and volcanic rocks exhibit some features of adakites.

近年来的研究证实，华北地台和大别—苏鲁造山带的中生代花岗岩与同时代的镁铁质超镁铁质岩有类似的Sr、Nd同位素特点，许多花岗岩和火山岩还具有类似埃达克岩的地球化学性质。

By analysing the molasse sediment, tectonic stress field, thrust fault system and comparing them with volcanic rocks and granites in the region, it is showed that Dabie orogenic belt had a strong intracontinental orogenesis whose deep dynamic processes were controlled by subduction with delamination during late stage of Cretaceous period-late Cretaceous period.

磨拉石沉积、构造应力场、逆冲断层系统和区域火山岩、花岗岩的综合分析表明，大别造山带早白垩世晚期—晚白垩世存在一次强烈的陆内造山作用，其深部动力学过程受控于拆沉中的俯冲作用。

This paper reports the zircon SHRIMP U-Pb age data for the Loufanggou metamorphic crystalline rock sheet amphibolite-leptite and biotite-bearing monzonitic quartz schist in the Xianghe area, Shangnan, Shaanxi, in the central part of the Qinling orogenic belt and discusses their geological significance.

其基底组成为广大地质学家所关注。

Not only is the present Yangtze craton constrained by regional compressional stress field but also its cold and dense lithospheric root is descended into the deep mantle by negative buoyancy, Which further strengthens inward obduction of orogenic belts surrounding it. For examples, Longmen shan mountain, Huaying shan and Bamian shan mountains override onto western margin and eastern part of Sichuan basin, respectively.

现今的扬子克拉通不仅受大区域挤压应力场背景制约，同时其冷而致密的巨厚岩石圈根正在向深部地幔下拽，从而进一步加剧了四周造山带向盆地的逆冲作用，龙门山、华蓥山和八面山分别向川西盆地和川东逆冲就是例证。
