A Major Key toward Uncovering the Asteroid Collision Process and the deep Earths Dynamics


Posted January 22nd, 2021 for JAMSTEC
1. Overview
A research group led by Dr. Naotaka Tomioka, Senior Researcher at the Kochi Institute for Core Sample Research of the Japan Agency for Marine-Earth Science and Technology (KOCHI JAMSTEC) gave the mineral name “poirierite” to a high-pressure phase with the chemical composition of olivine that was found in shocked meteorites. Poirierite has now been officially approved as a new mineral species by the International Mineralogical Association.
Olivine (peridot) is abundantly found not just in the Earth s upper mantle, but also in stony meteorites. Using a high-resolution electron microscope, the research group examined a meteorite that have been exposed to high-temperature and high-pressure environments caused by a mutual collision of asteroids. As a result, the research group made the world’s first discovery of a high-pressure phase of olivine called the “epsilon phase” in 2017 (more information c ....
