Cotopaxi Femont County, Colorado, USA Found 10/08/2000 Iron (Ungrouped, IAB complex) Richard and Sharon Walker found a single mass of 243 g while
prospecting for gold samples on a forested hillside with a metal detector. The
meteorite was buried about 20cm deep in soil under a small tree and the mass
was intergrown with the tree roots. Classification and analysis (J. Wasson, UCLA):
Metal composition determined by INAA is: Ni = 9.8%, Co = 0.50%, Ga = 48 mm/g, As = 17m g/g, Ir = 1.4 mg/g, Au = 1.7mg/g. The composition is unique compared to all other known meteorites.
Cotopaxi is an ungrouped member of the IAB complex. Type
specimens: 21.43 g, UCLA; 20.33 g, Denver Museum of Nature and Science.
