LL4-6 CHONDRITE METEORITE
628 GRAM MAIN MASS

Here we have a gorgeous angular to rounded breccia meteorite that encompasses several petrologic degrees. In addition to the spectacular matrix, this wonderful meteorite is full of natural beauty with contraction cracks, regmaglypts and a light coating of caliche. The stark contrast of the white caliche on velvety textured fusion crust enhances the allure of multi-colored breccia.
