Syn-Tectonic Dolomite U-Pb Geochronology Constraining Intracontinental Deformation: A Case Study from the Gelouang Gold Deposit in the Qinling Orogen, China

Determining absolute ages of orogenic faults is critical to understanding the deformation process in upper crust, but obtaining age remains a problem due lack readily available techniques. Carbonates occur as veins range geological settings, and thus it suitable mineral for U-Pb geochronology. Here, we apply new approach dating on syn-tectonic dolomite from Gelouang gold deposit western Qinling Orogen unravel timing fault formation shedding light regional crustal archive. In situ LA-ICP-MS yielding successful 115–112 Ma demonstrates that precipitated coeval with tectonic events ascribed post-orogenic phase Orogen. This event possibly correlated broader intracontinental processes might be an inevitable response extensional The presented successfully represents specific structure encompasses Moreover, utility method decipher complex histories scale.
