Popigai crater Totally Explained

Everything about The Popigai Crater totally explained

The Popigai crater in Siberia, Russia is tied with Manicouagan Reservoir as the 4th largest impact crater on Earth. A large bolide impact created the 100-kilometer diameter crater about 35 million years ago during the late Eocene epoch.
   The Popigai impact crater was possibly simultaneous with the Chesapeake Bay and Toms Canyon impacts, but evidence varies. For decades the Popigai crater has fascinated paleontologists and geologists, but the entire area has been off limits because of the diamonds and the mines constructed by gulag prisoners under Stalin.
   The impactor in this event has been identified as either an eight-kilometer diameter chondrite asteroid, or a five-kilometer diameter stony asteroid.
   The shock pressures from the impact instantaneously transformed graphite in the ground into diamonds within a 13.6 kilometer radius of ground zero. No exact count nor measure of caratage has been made available, but it's estimated that this one impact formed more diamonds than have been formed by the Earth's own processes.
   Popigai is the best example yet of the formation of a crater of this type. Three other craters are larger, but they're either buried (Chicxulub), strongly deformed (Sudbury), or deformed and severely eroded (Vredefort).
   The crater is just north of the Siberian city Norilsk, or 1 1/2 hours (by helicopter) from the outpost of Khatanga.
