Localities

At the type locality, the Northwest Africa 4964 meteorite (NWA 4964), Northwest Africa Meteorites, louisfuchsite is a new refractory mineral identified in a calcium - aluminium - rich inclusion (CAI) from the carbonaceous chondrite. It occurs with spinel, perovskite, grossmanite, plus secondary rutile, titanite and ilmenite in three regions in the inclusion.
Louisfuchsite is a new refractory phase from the solar nebula, crystallised from a refractory melt under reduced conditions (AM 109.11.2006-2012).
