英文摘要	The nondeformed, postcollisional Shahewan monzonite-minette complex in the North Qinling orogenic belt, central China, is composed of potassic monzonites and mafic minette dykes. The monzonites and minette dykes were coevally intruded as evidenced by a zircon U-Pb age of 211 +/- 2 Ma for the monzonites and a Ar-40/Ar-39 age of 209.0 +/- 1.4 Ma on the biotite from the minette dykes. These dates also indicate that the Shahewan complex postdated shortly the cessation of convergent deformation in the Qinling orogenic belt. The K-feldspar 40Ar/39Ar MDD, modeling result combined with the zircon U-Pb age reveals a rapid average cooling history (11.5 degrees C/Ma) for the complex from 211 to 150 Ma, implying a fast exhumation within a short period of time.
