Many orogenic belts in the world are formed by multiperiods compound orogeny. Different type of rocks, tectonics and metallogenesis are the recordings of orogenic activity (Deng et al., 2013; Li et al., 2013; Yang et al., 2014). Among them, Chert is one of the most characteristic sedimentary rock types which can suggest the sedimentary environment and the tectonic background. Qinling orogenic belt is an important belt which stretches from west to east of central China, and lots of Paleozonic chert outcrops were found in Mianlue tectonic zone which can reveal the sedimentary environment and tectonic background of Qinling orogenic belt. In this study, we have done research on Devonian cherts from Wenxian area in the west Mianlue tectonic zone, including field work of the cherts outcrops, petrology, mineralogy, major and trace elements of the cherts, and the sedimentary environment of cherts have also been analyzed (Baldwin et al., 2011; Ledevin et al., 2013). Combined with the studies related to cherts in the east of Mianlue tectonic zone (Li et al, 1997; Sheng et al., 1997; Zhang et al., 2003; Lv et al., 2004; Liu et al., 2005), we conclude the sedimentary environment and the tectonic background of Qinling orogenic belt in Paleozoic.
