摘要

Titannium mineralization was studied during the investigation on more than 5158 m of the drill core rocks from the Chinese Continental Scientific Drilling (CCSD). It is found that the most important economic titanium mineral is rutile and then followed by titanomagnetite. The major titanium-bearing rocks are:common rutile eclogite ,quartz rutile eclogite,and rutile/ V-Ti-magnetite eclogite, while phengite rutile eclogite,kyanite rutile eclogite and rutile biotite epidote uralitic rock (retrograded garnet pyroxenite) are the minor ore-bearing rocks. It is suggested that ultra-pressure metamorphic minerals and titanium originated from the mantle plume resulting from the Neoprotorozoic Rodinia supercontinent breakup event.
