Northwest Africa 2995 Superlative Complete Slice of the Moon
Lunar (feldspathic fragmental breccia)
This is a complete slice of a lunar meteoritethat is to say, a piece of the Moon ejected from the lunar surface following an asteroid impact. The one-pound meteorite from which this slice was derivedwhose name results from it having been the 2995th meteorite analyzed from the North West African grid of the Saharan Desert (see lot 30)was found in Algeria and purchased in Morocco in November 2005. The scientific abstract on NWA 2995 appeared in the Meteoritical Bulletin and accompanies this specimen.
Classified as a lunar feldspathic breccia; this lunar sample contains feldspar and is composed of angular fragments of older rocks that have been melded together following repeated impacts. This specimen contains geochemical components that are a signature of lunar breccias, along with minute amounts of meteoritic nickel-iron and veins of impact meltall of which are evidence of the lunar origin of the specimen as well as the asteroidal impact mechanism responsible for launching this sample off of the lunar surface. Moreover, this is an extremely fresh meteoriteit is not weathered as a result of exposure to Earths elements. With classic off-white anorthositic inclusions, this is an exquisite complete slice of the Moon for the discerning collector.(2)
