Writeup from MB 90:
Pedernales 30°20′N, 98°57′W Gillespie County, Texas, USA Find: 1 December 1980 Iron (ungrouped and related to IAB clan) History: Mr. John Stitt excavated a mass of 691 g from a depth of 4 feet from an Indian rock midden on ranch land close to Fredericksburg. Geochemistry: (J. T. Wasson, UCLA) Bulk composition: Co = 4.89, Ni = 75.0 (both mg/g); Ga = 65, Ge = 190, As = 16.4, Ir = 1. 17, Au = 1.455 (all µg/g). Classification: The stone is an iron of the IAB complex, but it is not a member of the IAB main group or the subgroups. It is closely related to Algarrabo and slightly further away in composition from Livingston (Tennessee). The kamacite bandwidth is 0.9 ± 0.2 mm (medium octahedrite). In some areas such bands have merged to create bands twice as wide. Specimens: A 23 g type specimen is on deposit at UCLA and one 86 g type specimen is on deposit at ASU. The main mass is held by B. Barnett. | ||||||||||||||||||
