| Research Abstract |
The ultrahigh-pressure metamorphic (UHP) rocks are those metamorphosed under high- pressure conditions where coesite (high-pressure phase of quartz) is stable, and they are known to occur mainly in collision belts between continent and continent. We performed studies of UHP metamorphic rocks from Czech Republic and Shangdong Peninula of China in order to elucidate what happened during such continental collisions. As one of the results, we revealed that UHP metamorphic rocks from Czech Republic experienced geologically very short heating only.
