主　　题：UHP high Why are Q-Ratios High in the Sulu UHP Metamorphic Rocks 

摘      要：I found high Q values （Q-ratio=Jn/Ji, .In, Ji are remanent magnetization and induced magnetization） in the Sulu ultrahigh pressure （UHP） metamorphic rocks, eastern China which is the world＇s largest UHP metamorphic belt （Fig. 1 in Liu et al., 2009）. Q values of 320 core samples with variable lithologies in the 100--2 000 m interval from the Chinese Continental Scientific Drilling （CCSD） main hole are as follows： values between 0.06 and 608.24, with an average of 15.56 for 171 eclogite samples;
