Classification: H6 Chondrite Shock Level: 4 Weathering Level: 5 TKW: 2008 grams Fullslice This meteorite was analyzed by Bathurst Observatory in March of 2007 as having a shock value of 4 and a weathering level of 5. It was originally found by Berber nomads in 2005, in Morocco/Algeria region of the Sahara Desert and came to the US via bulk shipment. Each specimen includes an Identification Card with complete details for your collection. Interesting to note is that this meteorite displays both metal veining as well as metal flecks. The stone analyzed by Bathurst Observatory displays both of these characteristics in one stone. The remaining endcut may be viewed The Main Mass may be viewed in The Foote Collection. Embedded in this meteorite are wonderful shock-veins and spot flecks of nickel/iron and presolar grains, which predate the formation of our solar system. These presolar grains originated elsew in the galaxy, meaning the specimen is composed of materials older than the Earth and her Sun itself!. Wikipedia describes chondrite meteorites in this manner: Chondrites are stony meteorites that have not been modified due to melting or differentiation of the parent body. They formed when various types of dust and small grains that were present in the early solar system accreted to form primitive asteroids. Prominent among the components present in chondrites are the enigmatic chondrules, millimeter-sized objects that originated as freely floating, molten or partially molten droplets in space; most chondrules are rich in the silicate minerals olivine and pyroxene. Chondrites also contain refractory inclusions (including Ca-Al Inclusions), which are among the oldest objects to form in the solar system, particles rich in metallic Fe-Ni and sulfides, and isolated grains of silicate minerals. The remainder of chondrites consists of fine-grained (micrometer-sized or smaller) dust, which may either be present as the matrix of the rock or may form rims or mantles around individual chondrules and refractory inclusions. Most meteorites that are recovered on Earth are chondrites: approximately 86% of witnessed falls are chondrites, as is the overwhelming majority of meteorites that are found. Shipping and Handling Costs: 1 item = $4.05 Shipping International shipping and handling, add $1.50 per item to the above schedule. All prices are in US Dollars.
