ME-612 Mills, New Mexico
"CM" Page 236. "ARN’S" Page 200.
Type: Stone. Olivine-bronzite chondrite (H6) Found: 1970.
Total known weight of the approx. 6 individual masses recovered was 88 kg. -- a fairly sizable amount for a stone. Availability on the market these days, however, is practically zero! This excellent example is an end cut with well preserved, red-brown fusion crust covering most of the back of the specimen. The cut surface of the specimen has been polished, and exhibits very tiny metallic inclusions disseminated over the entire cut surface. Numerous metallic gray-black veinlets, very obvious in the accompanying photograph, criss-cross the dark brown stone matrix. American Meteorite Laboratory (Glenn Huss) # H120.55.
Size: 1 3/4" X 1 3/4" across, X up to 3/4" thick. 63.20 grams
Price / gram: $3.25

ME-613 Santa Apolonia, Mexico
"CM" Page 314. "ARN’S" Page 279.
Type: Iron. Octahedrite, medium (IIIA). Found: 1872
This small example of the Santa Apolonia medium octahedrite has a thin, red-brown oxide patina covering all surfaces of the specimen. The octahedral crystal structure is demonstrated by the flat faces exhibited on some surfaces of the specimen. These are similar to the description of the stress induced cleavage cracks which followed the octahedric lamellae, noted on specimens from Gibeon -- see "Meteorite!" magazine, February 1997, Page 28. American Meteorite Laboratory specimen #112.
Size: 3/8" X 1/4"+ across, X 1/8"+ thick. 2.10 grams
Specimen price: SOLD

Type: Stone. Carbonaceous chondrite, type III (CV3).
With a total known weight of only 8.1 kg., found as two individual masses (1.6 kg. found in 1961/62, and a second individual weighing 6.5 kg., reported in 1970), the Leoville carbonaceous chondrite is considerably rarer than either of the two best-known carbonaceous chondrites -- Murchison, Australia, and Allende, Mexico. Information on analyses, and other important data about the Leoville CV3, can be found in the following texts:
a. "Meteorites and Their Origin", G. J. McCall, P. 95-96, and 182.
b. "Meteorites -- Their Record of Early Solar System History", J. T. Wasson, P. 164-165, with a black and white photo of a cut specimen of the Leoville CV3 appearing on P. 165.
The above referenced photo shows the gray chondrules, and white refractory inclusions, with ellipsoidal deformation. This ellipsoidal deformation of the chondrules is very obvious on all specimens, and is reported by Wasson to be caused by the heating of the meteorite "to a temperature of 1000 to 1200 K, at which temperature the silicates became plastic; then a shear force was applied that elongated one axis of the previously spheroidal grains". Wasson further states that "the only plausible mechanism for applying both heat and shear during a brief period appears to be to generate both by impact-produced shock". Unlike many carbonaceous chondrites, the Leoville CV3 has scattered, bright metallic inclusions. All specimens have at least one polished surface, and all of the larger examples (A. through D.) have modest amounts of thin, red-brown fusion crust present. American Meteorite Laboratory collection # H 40.65. Pricing is @ $50. / gram.
