DISCOVERY OF THE PANAMINT RANGE, CALIFORNIA, IRON METEORITE Name: PANAMINT RANGE Place of find: West slope of Panamint Range, Inyo County, California, USA. Approximately 36°30'N, 117°30'W. Date of find: Between 1950 and 1964. Class and type: Iron. Coarse octahedrite. Ni = 7.17%, Co = 0.3% (E. Olsen, analyst: X-ray fluorescence method). Number of individual specimens: 1 Total weight: 204 grams at present. Original finder cut off a small slice. Original weight estimated at 230 grams. Circumstances of find: Found by unnamed prospector, who, in 1960, left it with Mr. James Minette, mine geologist for U.S. Borax Co., Boron, California. Mr. Minette sent it to the Field Museum, Chicago, Illinois, in late 1973. Comments: Polished section studied by Dr. V.F. Buchwald of Copenhagen; it is a highly shock-altered iron of the crater-forming kind. Its location, about 680 km west of the Canyon Diablo find, and the absence of a known and verified meteorite crater in the area, strongly suggest it is a piece of transported Canyon Diablo meteorite. Superficially the piece looks very much like Canyon Diablo individuals, with small pockets of adhering clay in surface flutings. Its bandwidth, however, is at the lower limit of values reported for Canyon Diablo, 1.5-2.5 mm. The specimen is located at the Field Museum of Natural History, Chicago. Source: Dr. E. Olsen, Field Museum of Natural History, Chicago, Illinois, USA.

History: Found by a gold prospector in June 2018, 2.5 km SE of Hickman crater. The specimen was sold to a local mineral dealer who brought it to the 2020 Tucson Gem and Mineral show, where it was purchased by Keith and Dana Jenkerson and subsequently sold to Don Hurkot. Other meteorites have reportedly been found in the area. Physical characteristics: The irregularly shaped mass has a red-brown surface and numerous regmaglypts. Petrography: (C. Herd and P. Hill, UAb) Petrographic investigation of a 1 × 3 cm polished and etched surface reveals a well-developed Widmanstaetten pattern with kamacite bandwidth 1.1±0.3 mm (n=6), consistent with a medium octahedrite. No inclusions were observed. Terrestrial alteration extends along grain boundaries into the interior. Geochemistry: ICP-MS data, using sample of North Chile (Filomena) as standard (C. Herd, P. Hill, and S. DuFrane UAb): Ni = 7.7, Co = 0.48 (both wt%); Ir = 2.5, Ga = 64, Ge = 266, As = 16.7, Sb = 0.427, Ru = 4.8, Re = 0.23, Os = 2.2, W = 0.6, Pt = 5.5, Cu = 162 (all μg/g). Classification: (C. Herd, UAb): IAB iron, medium octahedrite. Most likely belongs to the Main Group, by comparison with Wasson and Kallemeyn (2002). Specimens: Type specimen consisting of a 27.0 g representative specimen at UAb. Main mass with Don Hurkot.

DISCOVERY OF MUNDRABILLA IRON METEORITE, WESTERN AUSTRALIA Name: MUNDRABILLA. The place of fall or discovery: The Nullarbor Plain, to the north of the Transcontinental Railway,Western Australia; φ = 30°47'S, λ =127°33'E. Date of fall or discovery: FOUND, March 1966. Class and type: IRON, medium octahedrite. Number of individual specimens: 2 Total weight: 10-12 tons and 5 1/2 tons. Circumstances of the fall or discovery: The meteorites were found by geologists R. B. Wilson and A. M. Cooney while engaged on a geological survey. Both masses are lying within only very slight depressions in clayey soil, some 180 m apart. The larger mass tends to have a crude conical to hemispherical shape with the nose partially buried in the soil. The axis is inclined at an angle of approximately 60°. Evidence of fragmentation of a larger mass is afforded by a sharp, angular, vertical face on the larger mass, which matches both in size and shape, a similar sharp face on the smaller mass. Preliminary study indicates that the meteorite came from the west at relatively low velocity and high angle. The larger mass has been presented to the Western Australian Museum, while the smaller mass is in Geosurveys possesion (Adelaide, South Australia). Source: Report of Dr. R. B. Wilson (Adelaide, South Australia) in a letter 1.4. 1967.

History: A single 8181 g mass was acquired at an estate sale in Shawnee, Kansas. The meteorite had been used for many years as a doorstop by a couple that lived in Shawnee. The owners of the meteorite originally owned farm ground in Barton County, Kansas, but lived for the better part of their lives in Shawnee. Unfortunately, the exact find location is unknown. A small end piece was sent to ASU and confirmed to be a meteorite. Physical characteristics: Surface shows some fusion crust and minor weathering with broad regmaglypts. Petrography: (L. Garvie, ASU) Etched sections show a coarse Widmanstätten structure, with stubby kamacite, bandwidth 1.3 mm. Kamacite lamellae display subboundaries and numerous μm-sized phosphide precipitates. Sub-millimeter schreibersite common within some kamacite grains and at grain boundaries. Neumann bands straight and well developed in rhabdite-free grains. Thin taenite and plessite cover several percent by area. Inclusions common - one 7 × 5 cm slice exhibits several (to 2 cm) irregular silicate-graphite-troilite-schreibersite regions. Silicates consist of olivine, low-Ca pyroxene, clinopyroxene, and plagioclase. Slice contains several 1-mm blocky schreibersite with cohenite rims. Geochemistry: Bulk composition: INAA data (Activation Laboratories - Ancaster, Ontario): Co 0.46 mg/g, Ni 74 mg/g, Ga 57 μg/g, Ge 180 μg/g, Ir 2.24 μg/g, and Au 1.50 μg/g. Classification: Iron meteorite, IAB-MG, coarse octahedrite, moderately shocked. Specimens: Type specimens - two slices with total weight of 144.6 g.

Petrography: UCLA samples from two masses; in these and in web photos, silicates are common. We examined two sides of a slice with total area 25 cm2. Silicate abundance ~15 vol%, troilite ~1.5 vol%. Kamacite lengths only ~1.5x widths, making width determination uncertain; best estimate 1.6±0.3 mm. Neumann lines abundant. Some silicates contain abundant small metal grains. A few large (3x4 mm) kamacite lamellae with incompletely resorbed taenite. Geochemistry: Co (mg/g) 4.55, Ni (mg/g) 68.8, Ga (µg/g) 81.6, Ge (µg/g) 370, As (µg/g) 4.1, Ir (µg/g) 4.1, Au (µg/g) 1.49.
