NEW NWA 4295 EL3 FOSSIL Enstatite Meteorite 3.9g


3.9 gram part slice of NWA 4295, a Rare EL3, W2-5 Enstatite Chondrite found 2005 in the Sahara Desert. Enstatites are very rare accounting for less than 2% of the chondrites. This very confusing meteorite has had several classifications including an Aubrite and EL6/7.  Although very sparse, non-metamorphosed chondrules were found leading to the latest EL3 classification.  It is interesting to note that this was recognized as a meteorite at all since it was found in a conglomerate and is thus considered a exceedingly rare fossil meteorite even though it is not completely weathered.  The interior of this meteorite is somewhat strange with its lack of metal, yellow color and odd compression veins.  NWA 4295 is very interesting to look at in the sunlight due to the brilliance of the enstatite crystals lending a sparkling appearance.  A total known weight of 312 plus grams is recorded under the nomenclature NWA 4295 but at least 70 kilograms can be accounted for in official pairings.
