Impactites

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

This impact breccia was found near the villages of Belchite and Fuendetodos near the center area of this large multiple impact structure. This amazing specimen displays sharp edged rock fragments imbedded in a matrix of pulverized rocks and crystallized calcite. This beautiful and colorful slice has dimensions of 106x68x12 mm and weighs 170.9 grams.

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

This is a must have 83.3 gram Metal Ore Copper rich Impact Breccia from the famous Sudbury Astrobleme Impact Structure in Ontario Canada. Its dimensions are 64x34x13 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 pieces you'll ever own. 

Mark Bostick wrote "About 1.87 billion years ago, an object from space nine kilometers in diameter slammed into Canada, a little north of Sudbury, Ontario creating the second largest impact structure on the earth. This impact was equivalent to a billion tons of TNT. An impact so big it cracked the earth, and in fact there are still earthquakes because of that event today!  The many mineral rich deposits and strange rock formations in such close proximity has attracted attention for 100's of years, long before its impact origin was known. 

Note that this is not a meteorite but a slice of Earth rock, altered by the impact of a very large meteorite.  This came from the ring of the impact and is the harder to find gold-copper-bronze colored impactite described as a metal-rich breccia and sulfides composed chiefly of some amount of iridium, cobalt & selenium. In addition, most of these specimens will contain nickel, iron, sperrylite and pentlandite as well as minor amounts of other metals, metallic & silicate minerals."

Note that this is a very fragile material so it will be packed with attention.  Would be a beautiful addition to any new or existing collection. Comes with a copy of a signed Mark Bostick Collection and a Canagem Collection specimen card. 

This is a must have 59.5 gram Metal Ore Copper rich Impact Breccia from the famous Sudbury Astrobleme Impact Structure in Ontario Canada. Its dimensions are 52x31x13 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 pieces you'll ever own.

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.
