The Springwater Pallasite was first found in 1931, and consisted of three masses of 85 pounds, 41 pounds, and 23 pounds. While there is a fair amount of the Springwater Pallasite in several of the well known institutional collections, there is not a lot of this Pallasite in the hands of private collectors. This may be due, in part, to the fact that the Canadian government has a ban on the export of Canadian meteorite specimens. Note that the Olivine in the Springwater Pallasite is dark yellowish-brown in color, and does not transmit light. In addition to the rich amounts of Nickel-Iron present, one can see small zones of metallic Schreibersite in association with some of the masses of included Olivine. The "Catalogue of Meteorites", 5th Edition, British Natural History Museum, M. Grade, P. 472 lists pertinent information about the Springwater Pallasite, and notes that Farringtonite, a rare hydrous magnesian phosphate, was first identified in the Springwater Pallasite. To date, Farringtonite has not been identified in terrestrial rocks, and has been identified in only one other Pallasite found in Krasnojarsk, Russia. Chemical composition of Farringtonite is Mg3(PO4)2.
This 176.30 gram part slice of the Springwater Pallasite has been beautifully polished on the front, or exhibit side. It was expertly re-finished at the Montana Meteorite Laboratory in 2002. The back of the specimen is rough sawed, and nearly 50% of the back exhibits the natural exterior surface of the meteorite as this slice was taken from near one of the ends of the meteorite specimen.

Many large examples of this large Pallasite were found, after the initial discovery of a 12 to 15 lb. mass in 1881. Total known weight, given in the "Catalogue of Meteorites", is over 80 kg. These three small specimens each have one cut and polished surface, with lots of bright metal present, in a matrix of dark brown Olivine. American Meteorite Laboratory # 8.60, 8.77, and 8.81.

Stone. Olivine-bronzite chondrite. (H4) “CM” REF: None - NEW! First found in 1971, this H4 stone was not identified and classified until 1989. The specimens listed below were obtained from the individual who originally made this find about two miles north of the City of Queretaro. The Queretaro is a weathered stone, found as a number of fragments which all fit together, with the total weight given as 11 pounds. Some of the fragments were found lying on top of the soil, and some were partially buried. Brian Mason classified the meteorite as an H4 chondrite, and the name was suggested by Roy S. Clarke, Jr., Curator of the Division of Meteorites at the Smithsonian Institution in Washington, DC. The physical appearance of this H4 chondrite is of a dark brownish-black stone matrix with small, very bright metallic flakes very richly disseminated throughout. The description of the Queretaro, Mexico meteorite appeared in “METEORITICS”, March 1990 (Vol. 25, No. 1), P. 60. A copy of the information from “METEORITICS” will be sent with any order for specimens from this locality, if requested. Each of the specimens listed below (items A through L) is a slice, with one surface polished. The bright silvery-metallic flakes are richly distributed over both cut surfaces of the dark brownish-black stone matrix, and are especially visible on the polished side of each specimen. Each slice is taken from a complete, natural fragment, so there are no “square cut” or “edge cut” specimens in this group. Slices are priced @ +/- $3.75 / gram. Item M) is a lot of small specimens and fragments, many with saw cut surfaces, and at least one specimen with a small polished surface, priced at +/- $4.00 / gram. Item N) is an end cut with the entire back and edges of the specimen in natural condition, as field collected. The cut surface shows the same distribution of small, bright silvery metallic flakes over the surface, enhanced by the polish on the contrasting dark brown-black stone matrix. Pricing is @ +/- $4.50 / gram. Order item ME-578, specimens A. through N.
