Certified NWA 7401, Enstatite chondrite EL-melt rock
BE 00
Only 2% Meteorites falling to earth are Enstatite chondrite
After having obtained all the analytical data and after having carefully evaluated them, taking
Into account the geological and meteorite standards mentioned in references, it is possible to
Conclude the meteorite is a highly weathered sample included in the ENSTATITE CHONDRITES type, plotting below the ordinaries chondrites group. Petrography; The sample displays a matrix dominated by orthopyroxene and secondary plagioclase with a size grain up to 100 micron. There are relic chondrules, radial pyroxene, with elongated crystals, Troilte, daubréelite and kamacite
Were observed as accessories. Sulfates and oxides in the boundary grains appear as residues of
Weathering.
For all these reasons, the analyzed sample for their characterization and analysis have yielded
POSITIVE results in its compatibility for meteorites, being in this case with NORTHWEST AFRICA 7401, Enstatite chondrite EL-melt rock.

Quick shipping with FedEx to the US. It was well packaged. The one I received did have a small crack and chip in the lip, but stuff like that is expected with a natural material like this. I'm happy with my purchase.
