“The Mangui meteorite is the newest meteorite fall in Yunnan, China on June 1, 2018. More than 500 fragments have been collected in a total mass of ~50 kg along the projectile area of about 20 km2 [1]. Mangui is classified as a L6 chondrite and its shock stage is S5 [1]. Here we report the progress on the high-pressure polymorphs from Mangui to constrain the P-T-t history of the shock processes for the parent body. “
