Chondrite H6.
Fell October 1991.

This meteorite underwent a violent impact event in space, reflected by the presence of shock-produced olivine glass exhibiting planar fractures, dislocations, mosaic and brecciated textures, solid-state transformation, melting and recrystallization. The shock peak pressure and temperature are estimated to be as high as 100 GPa and 2000 ℃.

a possible new phosphate phase of Na2(Fe,Mn)17(PO4)12
