The Piñon, New Mexico, Siderite

Abstract

The Pinon, New Mexico, siderite came into the writer's hands in May, 1932. The meteorite was a rather shapeless mass weighing about 17.85 kgs. (39 1/4 lbs.). It proved to be a nickel-rich ataxite, with a nickel content of 16.32%, according to a chemical analysis by F. G. Hawley, which is given in full. The meteorite is preserved chiefly in the State Agricultural College of New Mexico at Mesilla Park and in the Nininger Collection in Denver, Colorado.
