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.

History: The specimen was discovered by Faustino Asensio López in 1980 at an agricultural farmland where he often worked with his father. The iron was found about 1.5 km from Retuerta del Bullaque, Ciudad Real, Spain, close to the northern boundary of Cabañeros National Park. The finder recognized the unusual density of the rock and found no crater. For more than fifteen years the meteorite remained on the family home patio, and later was used as a weight for the ham-curing process. Mr. Asensio López suspected an extraterrestrial origin of the specimen when he watched a TV news report on the sighting of a meteor over Spain on February 28, 2011, so later that year he contacted Juan C. Gutiérrez-Marco (CSIC-IGE) and Rafael P. Lozano (IGME) to check the authenticity of the specimen. Physical characteristics: One mass of about 100 kg and average dimensions of 45 × 31 × 20 cm. Irregular but somewhat rectangular shape, with many concave surface features. The original surface shows moderate terrestrial weathering. Petrography: (R.P. Lozano, IGME; J.C. Gutiérrez-Marco, CSIC-IGE). Two etched sections (77.7 and 41.1 cm2) show a Widmanstätten pattern (bandwidth: 2.0 ± 0.3 mm), with abundant cohenite lamellae (9.5% of total area), irregularly bordered by accessory schreibersite and enveloped in swathing kamacite. Taenite is present in 0.02-0.3 mm thick lamellae along kamacite and between kamacite bands (0.3-4 mm max. size pearlitic plessite). There are abundant kamacite grains showing polygonal sectors, with conspicuous Neumann lines and without cohenite. The larger sections display eight irregularly shaped graphite-FeS nodules (max. size, 5-12 mm), located in the central areas of the kamacite polygonal sectors. Each of the nodules has a 1-3 mm-thick rim of schreibersite + cohenite. Geochemistry: (Jesús Reyes, IGME). Bulk composition: Ni = 7.527, Co = 0.475 (ICP-AES data, in wt%). Ga = 68.9, Ge = 365, As = 13.7, W = 0.95, Ir = 1.95, Au = 1.695 (ICP-MS data, in ppm). Classification: (R.P. Lozano, IGME). Iron meteorite, coarse octahedrite, IAB complex (MG), cohenite rich, moderate weathering. Specimens: A 1278 g type specimen, two fragments of 388 and 50 g, and three polished sections at IGME. The finder, F. Asensio López, and his brothers hold the main mass of about 98 kg.

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.
