///The high Fe-Ti eclogites appear at the depth intervals from 318～380 m (A); 420～470 m (B) and 530～600 m (C) respectively in the Chinese Continental Scientific Drilling (CCSD) Project main hole. They have high FeOT (total Fe) abundances of average 15.36%, 14.09% and 20.83%, high TiO2 concentration of average 3.89%, 3.28% and 4.10% and low SiO2 contents of average 44.64%, 48.64% and 41.10%, respectively. The magnetic property compared with metamorphic petrology of high Fe-Ti eclogites suggests that section A samples represent magnetic properties of the fresh or slightly retrograded eclogites, section B samples show higher metamorphic retrogression than those of section A, section C samples are fresh eclogite, whose density and oxygen fugacity are distinctly higher than those of A and B, containing a lot of hematite-ilmenite lamellar textures formed during the slowly exhumation, which can be the main contributors to the high NRM of the section C eclogite.
