47.5g ZHAMANSHINITE Impact rock from the Zhamanshin meteor crater
On Offer: 47.5 gram ZHAMANSHINITE Impact rock
Origin: West Coast, Tasmania, Australia
Description: This is an amazing 47.5 gram specimen of Zhamanshinite impact rock.
The Zhamanshin crater was created about a million years ago in Kazakhstan, the meteorite crater lies about 100 kilometres northeast of the small sea and it is known to be one of the most recent and violent impacts on the planet.
The Zhamanshin crater is 14 kilometres in diameter and reaches a depth of 300 m. Throughout the area, the earth has been stirred over several strata and today there are fossilized corals and shells on the surface of the ground as well as many tektites and different types of impact melts including the less dense frothy rocks as well as darker dense impact glass, as the result of a transformation of the rock due to the heat released by the impact.
The energy released was equivalent to several dozen Hiroshima bombs. It had the same effect as what is called a "nuclear winter" and the impact caused fires and smoke emissions that caused all animal and plant species to disappear within a radius of several hundred kilometres.
What you get: 47.5 gram Zhamanshinite impactite specimen, as shown, and Certificate of Authenticity signed by Top Meteorite's Curator of Collections.
