Extension in the graben systems around the Ordos (China), and its contribution to the extrusion tectonics of south China with respect to Gobi-Mongolia

Thrusting and exhumation of the southern Mongolian Plateau: Joint thermochronological constraints from the Langshan Mountains, western Inner Mongolia, China

“…Pliocene-Quaternary active mountain-front normal fault, as part of the Ordos graben system (Zhang et al, 1998), separates the Langshan Mountains from the Jilantai-Hetao Basin (Fig. 2), in which more than 10 km thick fluvio-lacustrine clastic sediments have been deposited during the Cenozoic (SSBC, 1988).…”

Mesozoic large magmatic events and mineralization in SE China: oblique subduction of the Pacific plate

“…The Shizhuyuan W-Sn deposit occurs along the contact between a Late Devonian dolomitic limestone and a Jurassic to Cretaceous granitoid pluton . This deposit contains Downloaded by [Guangzhou Institute of Geochemistry] at 00:00 09 February 2012 750,000 t WO 3 , 490,000 t Sn, 300,000 t Bi, 130,000 t Mo, and 200,000 t Be with combined WO 3 grades ranging from 1 to 5% (Wang et al 1987;Zhang et al 1998;Lu et al 2003). In addition, the deposit is rich in fluorine with a reserve of 76 Mt at 2% fluorite, making it one of the largest fluorite deposits in China (Liu et al 1995;Lu et al 2003).…”

Crustal structure of the northeastern Tibetan plateau, the Ordos block and the Sichuan basin from ambient noise tomography

“…During this process, strain accumulates slowly along the Lonmenshan Fault zone, which then generated the 2008 May 12 th Wenchuan earthquake , for example. Lower crustal flow is assumed to split into two branches: one channel thought to flow to the south of Longmenshan Fault and finally to the Yunnan region and the other is believed to flow northeast along the Qingling Orogen between the Ordos and Sichuan blocks (Zhang et al, 1998;Huang et al, 2008). The status and mode of the crustal flow still remain unclear, however.…”
