2 and Sr/Y of the granitoid rocks during this period indicate prominent involvement of mantle-derived melts mixed with crustal melts. The granitoid rocks with higher SiO 2 and Sr/Y during 225–205 Ma, however, suggest they are formed under a greater pressure than those of previous period (235–225 Ma) granitoid rocks. This conclusion has important implications for geochemical studies, since the whole-rock major-, trace-element and isotopic composition can be used to study the petrogenesis of such granitoids even if they underwent high-grade granulite-facies conditions.vs. closed-system behaviors in granitoid rocks during granulite-facies metamorphism: a case Granitoid rocks can be subdivided in two main ways: (1) by referring to geographically contiguous bodies (batholiths); and (2) by reference to groups of rocks which have similar chemistry, mineralogy, and usually age (suites).

Samples used in this study are outlined and are those that meet the criterion for M.The ranges of zircon saturation temperatures for samples with M ≤ 2 are listed in each panel, utilizing the Boehnke et al. (2013; B et al.) and Watson & Harrison (1983; W & H) equations. A granitoid meets two criteria: (1) it is a plutonic rock that (2) has between 20 percent and 60 percent quartz.
