The Zhamanshin impact crater in Kazakhstan was created by a massive meteorite impact during the Pleistocene period. The eroded crater is still visible today and is approx. 14km (8.7 miles) in diameter. In addition to the usual rocky breccias, there are examples of a glassy impact melt that is similar to the melts seen at other craters like Ries (Germany) and Darwin (Tasmania). Some variations of the glassy material are dark in color and heavily striated with plastic melt flow lines. These pieces bear a resemblance to Darwin Glass in hand.
Zhamanshinite is rarely seen on the collector market and is a difficult locality to acquire due to export restrictions and a limited available supply.
The specimen being offered here is a large fist-sized specimen that weighs approx. 181 grams. It shows layering and melt flow.
