Portales Valley

Country: USA
Region: New Mexico
Fell: 1998, June 13, 07:30
Group: Stone-iron
Type: Chondrite
Class: H6
Total known weight: 71.4 kg

Portales Valley is an extra-ordinary chondrite. The classification H6 based upon the olivine fayalite, is an over simplification of a complex meteorite. More appropriately classified an H7, metallic-melt breccia with affinities towards the metal-rich primative achondrites. (MaPS 40). About half of the meteorites recovered from this fall are considered metal-rich containing up to 50% metal arranged as a medium octahedrite which is unpresidented in type H ordinary chondrites. We have preserved a impact pit or crater (if you will) caused by a 2.53 kg specimen that landed in a paved county road.
