» Meteorite: NWA 4967

Northwest Africa 4967
Algeria
Find: 2007
Classification: Carbonaceous chondrite (CO3.2)

History and Physical Characteristics:
Two very dark stones that weigh a total of 689 g were purchased in Erfoud in August 2007. Some fusion crust remains, although eolian processes have pitted and polished the stones to a shiny black luster.
Petrography (T. Bunch and J Wittke, NAU):
The interior is also very dark and structure is only recognizable in thin section. Consists of closely packed chondrules, CAIs and AOAs, matrix poor (vol. % = 18). Olivine dominates the matrix together with pyroxenes, FeS, pentlandite, and metal. The stones are moderately weathered with low shock level.
Mineral compositions:
Olivine, Fa2.1 to 63, Cr2O3 in type II PO olivine is 0.08 to 0.40 wt % with a peak at 0.26 wt %; FeO/MnO = 77-129.

689g	Name : NWA 4967 Class : Carbonaceous Chondrite CO3.2 S2/W1-2 Region: Erfoud, Maroco Date : 08.2007 TKW : 689g Complete specimen was put together like puzzles. One of fragments is black from outside, and other two are brown. Propably first one was on surface and two other was found underground. Meteorite have many very small chondruls. This is difficult to show on photos. Matrix and chondruls have similar, near black color.
