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 impact breccia was found in the area of the village of Fuendetodos 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 117x79x9 mm and weighs 163 grams.

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

This is a must have 209 gram polymict impact breccia from the Lockne Crater located approximately 21 km south of the city of Östersund in northern Sweden.  It is amazingly light considering its mass of 132x63x23 mm.  Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection items you'll ever own. Impactite is a slag-like glassy object found on the surface of the earth, formed from rock melted by the impact of a meteorite.

The term impactite encompasses shock-metamorphosed target rocks, melts or suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components and shocked mineral grains, tektites, anomalous geochemical signatures, etc.

Lockne is a 7.5km-wide impact structure that formed circa 455 Ma when an L-chondritic asteroid impacted mixed sedimentary and crystalline target rocks that were under a shallow epicontinental sea (500m deep) at the time. The feature and its surrounding impactite deposits were covered by Caledonian thrust nappes that also partly folded them.

Erosion has breached much of the overthrust rocks to show the impact site. Impactites include the Loftarstone (graywacke-like arenite with carbonate grains), Lockne Breccia (polymictic but mostly limestone clasts), Resurge deposits, Ynntjämen Breccia (monomictic, matrix-supported with calcareous-argillaceous matrix) and the Tandsbyn Breccia (monomictic crystalline ejecta).  This crater has been suggested to be a doublet with the nearby smaller Målingen Crater, 16 km apart.

This gorgeous large slice displays very well.  It would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

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.

A prehnite and apophyllite crystal cluster is a visually appealing combination of minerals often found together due to shared geological conditions. In this cluster, the Prehnite with its pale blue color and rounded formations, complements the colorless or white, well-defined crystals of apophyllite. The contrast in colors and crystal structures creates a beautiful specimen. This unique combination is associated with properties such as calmness, protection, spiritual growth, and clarity.

Prehnite is a green to yellowish-green colored mineral that belongs to the phyllosilicate family. It is composed of calcium, aluminum, and silicate, with traces of iron, magnesium, and other elements. Prehnite crystals have a unique pearly luster and can form in a variety of shapes, including tabular, prismatic, and stalactitic formations.

Prehnite is believed to have a calming effect on the mind and emotions, promoting relaxation and inner peace. It is also said to be a stone of unconditional love, compassion, and healing.
