Meteorite**SUTTER'S MILL, C Carbonaceous**0.184 grams, Unobtainium Meteorite!!!!

Description

Hello up for sale is one of the most rare and hardest to find meteorites ever SUTTER'S MILL classified as a ver rare (C) Carbonaceous. This gorgeous fragment weighs 0.184 grams with nice fresh fusion crust, and very fresh matrix, extremely fresh. This meteorite has a total known weight of only 993 grams and its becoming almost impossible to find any of this for sale, no more material will ever be found in the field.  As of November 27th, 2012, 90 fragments have been recovered with a total mass of 992.5 g. A tally is maintained at the Sutter’s Mill. This meteorite comes with 2 COA cards Streaming Meteorites and Mark Lyon. Thanks for your interest and take care.
History: (P. Jenniskens, SETI): A bright daytime east-to-west moving fireball was seen on April 22, 2012, from locations over California and Nevada between 7:51:10 and 7:51:30 am local daylight time (UT-7). The meteoroid fragmented towards the end of its trajectory. A loud sonic boom was heard in a wide region around Lake Tahoe. Wind gusts were felt and houses shook. At least a kiloton of kinetic energy was released, based on the infrasound signal detected at two stations. Eye witnesses in the townships of Coloma and Lotus, El Dorado County, reported hearing whistling sounds and some smelled a "welding" odor. U.S. National Climatic Data Center’s "NEXRAD" Doppler weather radar sweeps detected the falling meteorites. In data analyzed by Marc Fries, PSI, and Robert Matson, SAIC, the radar-defined strewn field is centered on the Sutter’s Mill historic site. On April 24, Robert Ward searched under the radar footprint and collected the first 5.5 g meteorite in Henningsen-Lotus Park. Later that day, Peter Jenniskens recovered a crushed 4 g fragment in the parking lot of that same park. A third find was made by Brien Cook, before heavy rain descended on the area in the following two days. After the rains more fragments were found including at the Sutter’s Mill site in the James W. Marshall Gold Discovery State Historic Park.
This meteorite comes with COA card and display case. Thanks for your interest and take care.

Petrography: (M. Zolensky, JSC): A small piece was examined for petrography, taken from the stone found by Jenniskens on the parking lot surface, which had been crushed by an automobile tire and had some adhering terrestrial soil. The meteorite is unusually hard compared to CM2 chondrites, and microprobe totals for the matrix are also high for CM2, suggesting possibly incomplete aqueous alteration or, alternatively, mild thermal metamorphism.  Various coarse-grained components are embedded within an opaque fine-grained matrix including chondrules, fine-grained porous olivine aggregates, fine-grained porous low-Ca pyroxene aggregates, large isolated lithic and mineral fragments (both olivine, low-Ca pyroxene), abundant CAIs, and grains of pyrrhotite and pentlandite. The components are often rimmed by fine-grained dust mantles. Chondrule diameters are generally less than 0.4 mm with a few exceeding 1 mm. Some chondrule contents are partially altered to tochilinite and cronstedtite and/or serpentine. Fe-Ni metal occurs (as a minor constituent) in chondrules and aggregate olivine crystals. The porous aggregates are irregular in shape and measure up to a couple of hundred microns across. The CAI are typical layered CM variety, with spinel cores, diopside rims and cronstedtite or Fe-rich serpentine between. The matrix includes abundant tochilinite intergrown with serpentine with a layered structure.  Veins are present consisting of pyrrhotite, pentlandite, and Fe-Ni-Cr phosphides. One small, embayed grain of oldhamite was observed in matrix.  Several grains of a refractory carbon phase were observed in the matrix, measuring up to 10 µm. No carbonates were observed.
Scientists have examined a stone from the Sutter’s Mill parent body that was collected before heavy rain fell on the site of the Sutter’s Mill impact. The study shows that Oldhamite is present in the sample, while samples that were rained on do not contain the mineral. The study provides new insights about composition of the parent body from which the Sutter’s Mill stones originated, and the processes that shaped its mineral composition. The study also highlights the importance of collecting samples as quickly as possible after a meteorite fall has occurred, thereby limiting the effects of terrestrial alteration.
