Impactites

This is a must have 76.5 gram Impact Vesicular Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in South Western France, near the village of La Valette. Although not a meteorite, impactites are directly linked to them and their impacts and are probably going to be one of the rarest collection item 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. This impactite was formed 186 million years ago.   This deformed rock fragments and partly molten are imbedded in a melt matrix showing typical flow structures from former melt.

This gorgeous end piece displays very well with a mass of 92.3 x 71.3 x 9.8 mm. Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.

The Puerto Minguez ejecta refers to the impact ejecta from the 38 million years old twin (multiple) impact structure Azuara / Rubielos de la Cerida in Northern Spain, originating from the nearby Rubielos de la Cerida impact structure.

This is a strongly deformed limestone component (seldom different rock types) with significant displacements. Typical clast deformation looks looking like a loaf cut into slices but not fully broken into pieces.  This is typical of a short-time dynamic deformation under high confining pressure.

The similar deformations are well known from the Ries crater impact ejecta that occurred in carbonate concretions and in the famous Ries Belemnites both embedded within soft Jurassic claystone. This sample shows a limestone clast partially sliced / fractured with prominent displacements in the range of up to 12 mm. The over all dimensions of this sample is 40x60 x125 mm and weighs 365 grams.

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