The pinakiolite structure appears to be preferred to the ludwigite structure at tem- peratures below 900. This suggests that pinakiolite is also a low strain structure and that ludwigite and pinakiolite are not at the extreme ends of a series related by cation vacancy concentrations but instead are low and high temperature phases.Blatterite (Mn2+,Mg)35(Mn3+,Fe3+)9Sb5+ 3 (BO3)16O32 c 2001-2005 Mineral Data Publishing, version 1 Crystal Data: Orthorhombic.
