Polymict Impact Breccia | 53 Grams | Azuara Impact Structure, Spain | SO24

The Azuara polymict impact breccia refers to the impact material from the 38 million year old twin (multiple) impact structures Azuara / Rubielos de la Cerida in Northern Spain.

This polymict impact breccia was found in the area of Santa Cruz de Nogueras near the center area of this large multiple impact structure.  This is partly melted and/or decarbonized limestone fragments in a dense and extremely hard matrix showing flow texture.  The breccia is considered an equivalent to suevite impactites in other impact structures. This beautiful slice has dimensions of 68x47x12 mm and weighs 53 grams.

Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
