 note = {The Dongqing pluton in the Zhangguangcai Range, NE China comprises two-mica monzogranite and garnet-bearing two-mica monzogranite with subordinate garnetbearing muscovite alkali-feldspar granite. The monzogranite was dated as 208 Ma by the ^208Pb/^232Th monazite dating (Fang, 1992) and ca. 160 Ma by the Rb-Sr and Sm-Nd methods (Wu et al., 2004). To examine the discrepancy, monazite from the monzogranite was dated by the CHIME method coupled with age mapping. Monazite grains show significant compositional variation in concentric and sector fashions, but are chronologically uniform. Individual sets of ThO2, UO2 and PbO analyses were screened by the chemical criteria, 0.96<(Ca+Si)/(Th+U+Pb+S)<1.05 and K2O<0.02 wt.%. The screened data points are arrayed linearly on the PbO vs. Th02* diagram and define an isochron of 159.0±4.8 Ma with an intercept value of 0.0030±0.0017, suggesting that the older isotopic monazite age is possibly resulted from the sizable amounts of initial Pb. Present CHIME monazite dating reinforces that variety of peraluminous rocks in the Dongqing pluton formed at about 160 Ma through the late stage of magmatic differentiation and magma-fluid interaction.},
