“…The former collision developed the Shangdan suture zone and East Qinling south-vergent thrust system (Mattauer et al, 1985;Meng and Zhang, 1999;Xu et al, 1992), and the latter the Mianlue suture zone (Meng and Zhang, 1999). Around the time, two-stages of granitoid magmatism occurred in the Paleozoic (507-400 Ma) and Early Mesozoic (252-185 Ma), both which were considered to be associated with above two important orogenic processes (Wang et al, 2013b).…”

“…We assume that the latter could not be detached before the Silurian accretion to Gondwana of some exotic (Baltica±Siberia) elements grouped here as Serindia. There, the situation is quite different, amalgamation of terranes happened only in Silurian or Early Devonian times and larger continental fragments are involved such as the Pamir±south Tarim±Tsaidam block collision with the north Tarim±north China block (Yin and Nie 1996) or the north Qinling north China blocks collision (Meng and Zhang 1999). These drifting exotic blocks (Serindia terrane) followed the slab roll-back of the ProtoTethys accompanied by the Asiatic ocean spreading in a back-arc position.…”

“…1a). It is at a key tectonic position, been considered as a composite orogenic belt, formed by the collision of the South China and North China blocks (Mattauer et al, 1985;Sengor, 1985;Zhang, 1985;Ren et al, 1986;Hsu et al, 1987;Zhang et al, 1987Zhang et al, , 1989Enkin et al, 1992;Kröner et al, 1993;Li et al, 1993;Okay and Sengor, 1993;Ames et al, 1996;Zhang et al, 1996a;Hacker et al, 1998;Meng and Zhang, 1999;Faure et al, 2001;Zhang et al, 2001;Ratschbacher et al, 2003Ratschbacher et al, , 2006Dong et al, 2011aDong et al, ,b,c, 2012aBader et al, 2013a,b;Dong et al, 2013;Li et al, 2015;Dong et al, 2016). Qinling orogenic belt has preserved a lot of kinematic evolution records of long-term multiple stages subduction and collision between the South China and North China blocks, as well as tectonic records of overthrust thrusting, strike-slip regulation, extensional collapse, been a good region for studying orogenic tectonic process.…”

The Dabashan thrust nappe structure at the southern margin of the Qinling orogenic belt suffered at least two stages of evolution which are Late Triassic plate subduction collisional orogeny between North China block, Qinling micro-plate and Yangtze block followed by intracontinental orogeny since the Meso-Cenozoic. A prominent topography characteristic within the Dabashan area is a southwestward extrusive arc (Bashan Arc fault) that is one of key factors to understand the geodynamic condition of the Dabashan thrust nappe structure.In this work, two-dimensional plan-view models are constructed to simulate the collisional and intracontinental orogenic movements, and the factors that may control the formation of the Bashan Arc fault are analysed. The modelling results show that the compressive stress produced by the plates collision along both north and south boundaries is the main driving force. The dextral shearing derived from the inconsistent shape on the block margins is the main controller. Rigid tectonic units such as Bikou and Hanan-Micangshan terranes, Foping and Wudang domes, as well as Shennongjia-Huangling anticline also contribute as "anchor" effects. Additionally, the rheology properties of rock material in the Dabashan area affect the shape of the arc.La estructura de la falla de cabalgamiento de las montañas Dabashan en el margen sur del cinturón orogénico de Qinling sufrió por lo menos dos etapas de evolución, la colisión orogénica del Triásico Superior entre el bloque de la China del Norte, la microplaca de Qinling y el bloque Yangtze, y la orogénesis intracontinental desde el Meso-Cenozoico. Una característica topográfica prominente del área de Dabashan es un arco extrusivo (falla Arco de Bashan) hacia el suroeste, que es un factor determinante para entender la condición geodinámica de la falla de cabalgamiento en las montañas Dabashan. En este trabajo se construyeron modelos bidimensionales planos para simular los movimientos de colisión e intracontinental orogénicos y se analizaron los factores que podrían controlar la formación de la falla del Arco de Bashan. Los resultados del modelado muestran que el esfuerzo de compresión producido por las placas de colisión en los límites norte y sur es la principal fuerza impulsora de la falla. La principal controladora es la fuerza de cizallamiento dextral derivada de la forma inconsistente en los margenes del bloque. Las unidades tectónicas rígidas como los terrenos Bikou y HananMicangshan, el domo Foping y Wudang, al igual que el anticlinal Shennongjia-Huangling tienen funciones de ancla. Adicionalmente, las propiedades reológicas del material rocoso en el área Dabashan afectan la forma del arco. Condición geológica y geodinámica para la formación estructural de la falla de cabalgamiento en las montañas Dabashan basada en el modelo numérico del software FLAC B2 Xiaoning Zhang and Yunpeng Dong.
