Mid-paleozoic collision in the north Qinling: Sm-Nd, Rb-Sr and 40 Ar/ 39 Ar ages and their tectonic implications
Different isotopic geochronometers have been used to study the nature of the mid-Paleozoic tectonothermal event in the North Qinling arc system at the southern margin of the North China Block. 40Ar/39Ar age of amphibole from sample QH-3 (426 ± 2 Ma), Rb-
