Tectonic setting of Devonian sediments in the Qinling orogen:Constraints from detrital modes and geochemistry of clastic rocks
秦岭造山带泥盆系形成构造环境：来自碎屑岩组成和地球化学方面的约束

Devonian sediments in the Qinling orogen predominantly crop out between the Shandan and Mianlue sutures. Abundant Au, Ag and Pb-Zn deposits in the Devonian strata have attracted considerable interest since the late 1960s, but provenance and tectonic setti
