Dellenite Impact Melt Rock | 80.5 grams | Dellen Crater, Sweden

This is a must have 80.5 gram Impact Melt Rock from the Dellen Crater, north of Stokholm, Sweden. Some locals call these rocks by the name of “dellenites”, although officially they are impact melt rocks.  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.  Dellen impactites were divided into three impactite groups: (i) suevitic impact breccias with lithic and melt clasts, (ii) impact melt rocks, and (iii) shocked (parautochthonous) target rock. In turn, impact melt rocks were divided into (i) clast-rich, (ii) clast-poor, and (iii) clast-free types.  The Dellenite type material was classified as clast poor impact melt breccia.

This gorgeous slice displays very well.  It is amazingly light considering its mass of 87x73x6   mm.  Would be a beautiful addition to any new or existing collection. Comes with a Canagem Collection specimen card.
