Estimated delivery between 29 December and 03 January.
This is a must have 17 gram Impact Melt Rock from the Stac Fada Member Impact Structure, NW Scotland. It measures 65x38x4 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 beautiful Impact melt rock comes from the Stac Fada impact structure in Scotland. The structure has an estimated age of about 1.2Ga (1,200 Ma). The Stac Fada Member of the Precambrian Stoer Group in Scotland has previously been described as volcanic in origin. However, shocked quartz and biotite provide evidence for high-pressure shock metamorphism, while chromium isotope values and elevated abundances of platinum group metals and siderophile elements indicate addition of meteoritic material. Thus, the unit is reinterpreted as having an impact origin.
This gorgeous slice displays very well. Would be a beautiful addition to any new or existing collection. Comes with two a Canagem Collection specimen card.
