| Research Abstract |
Microtextures and mode of occurrence of sulfides in coesite-grade ultrahigh-pressure metamorphic rocks imply that Fe, Cu, Ni and Co coexisted in the single sulfide phase in high pressure condition whereas decompression firstly caused Cu- and Fe-bearing sulfide to behave independently and secondly caused independent behavior of Co-, Ni- and Fe-bearing sulfides by further decompression. This observation implies that the behavior of sulfides and the elements therein are controlled not by temperature change alone but by pressure change as well.
