Impactites

This is a must have 130 gram Impact Breccia also referred to as Suevite coming from the famous Rochechouart impact structure in South Western France,.  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.

Named after the town of Rochechouart, the Rochechouart impact structure is located on the western margin of the French Massif Central near the city of Limoges, approximately 350 km (220 mi) south of Paris. Rochechouart (population about 3800) is built with rocks created or modified by the impact (impactites).

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.

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 is a must have 21.3 gram Impact Melt Rock from the Dellen Crater, north of Stokholm, Sweden.  It is amazingly light considering its mass of 39x39x9 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.

This impactite was formed approx. 89 million years ago when a meteorite crashed into the earth making a round crater which is now a lake about 11 miles wide. The term tagamite was introduced in 1975 to describe impact rock from the Popigai crater in Russia. Varieties of tagamites are described based on crystallinity, texture and clast content.   HT Tagamite differs from other material due to the complete melting of the crystalline matrix and then being subjected to rapid cooling.

This is a rare and fantastic 2.2 gram Libyan Desert Glass from Kuffra, Libya, with dimensions of 21x17x7 mm. 

Although its exact origin is still debated, the leading theory suggests it was formed by a high-energy event, such as a meteoric impact or airburst, that melted the desert sand directly where it lay, without being ejected into the atmosphere and re-entering. This results in different physical characteristics compared to tektites​. Libyan Desert Glass is found specifically in the Great Sand Sea of the Eastern Sahara, within a more localized area spanning parts of western Egypt and eastern Libya.

This is a great 50.7 gram Impact Melt Breccia from the Sääksjärvi crater in Finland. It is amazingly light considering its mass of 54x42x25 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 item you'll ever own.

Sääksjärvi is a lake in Kokemäki, Satakunta, western Finland, east of the town of Pori. The lake is notable because it overlies an impact crater.  The crater is 5 kilometres (3 mi) in diameter and is completely buried under the lake and is not visible at the surface. The age of the impact structure is estimated to be about 543 ± 12 Ma (million years ago), at the boundary between the Ediacaran and Cambrian periods. There are impactite rocks in the southwestern region from the crater confirming its extraterrestrial origin. At the time of its discovery, only one impact crater (Lappajärvi) was known in Finland.

This is a fantastic Impactite Fallback Breccia from Germany weighing 69.2 grams and measuring 72x66x10mm. Although not a meteorite, impactites and shatter cones are directly linked to them and their impacts. The Steinheim Basin today exhibits a distinct morphological depression that is ∼110 m deep and ∼3.5 km in diameter; the height of the central uplift totals to more than 140 m. The original size of the pristine crater is estimated to be ∼3.8 km with an original depth of ∼205 m.

As this drainless morphological depression was filled by lake sediments shortly after the impact, the primary crater morphology is widely preserved. The crater rim is formed by steeply inclined and intensely brecciated Upper Jurassic limestone blocks that also contain numerous shattered chert nodules, as well as some loose blocks of the host limestone. An impact breccia, referred to as the so-called ”Primäre Beckenbrekzie” (“primary basin breccia”) and interpreted as a “fallback breccia”, is known from many drillings in the Steinheim Basin.

Mainly composed of Middle to Upper Jurassic limestones, marls, mudstones, and sandstones, the impact breccia inside the morphological depression of the Steinheim Basin is overlain by lake sediments and is obviously preserved in its original thickness and position.   This piece displays very well and is a very nice size showing multiple characteristics of its origin. Would make a beautiful addition to any collection.
