Early Jurassic magmatic rock are widely existed in Nanling Range, but whether contemporaneous mineralization develops there or not still unknown. In this paper, a research combined of LA-ICP-MS zircon U-Pb and phlogopite 39Ar-40Ar chronology are firstly report on Shibei stock and skarn Iron-Tin orebody of Dading deposit, confirming Early Jurassic mineraliztion event exists in this region. The result shows monzogranite and granodiorite of shibei had LA-ICP-MS zircon U-Pb ages of 187.5±1.8 Ma（MSWD=0.81） and 186.9±2.0 Ma（MSWD=1.15）respectively, and skarn Iron-Tin orebody had 39Ar-40Ar plateau age of 184.5±2.6 Ma( MSWD= 0.83), with an isochron age of 184.5±2.6 Ma( MSWD=0.83). The formation of Dading deposit is the first mineralization event in Nanling Range by high resolution data, which providing a new choice in the mineral exploration and evaluation in this region. Furthermore, through analysis of the magmatic direction, rock association in Early Jurassic and tectonic involvement of Cathaysia block in middle to late Mesozoic, a cognition of post-orogenic extension or collapse process controlled Diagenesis and mineralization in late Indonisian orogeny may be more appropriate to explan the formation of Dading deposit.
