The impact (cosmogenic) origin of this unique structure, as well as the Sudbury intrusive complex and ores therein, has been admitted by all researchers. In this respect, the Popigai astrobleme (100 km across) with the largest (except for the Sudbury astrobleme) volume of impact melting ...

The 35.7 ± 0.2 Ma old Popigai crater, Siberia, with a diameter of about 100 km is one of the best preserved large terrestrial impact structures. The heterogeneous target at the impact site consists of Archean to Lower Proterozoic metamorphic rocks of the crystalline basement, Upper Proterozoic ...

Popigai, RussiaThe Popigai impact crater is located on the northern margin of the Anabar shield in Russia, where dolomites, quartzites, sandstones, and siltstones overlie the basement gneisses, and with its 90 km of diameter, it is the country's largest impact structure....
The structure is characterized by a gravity anomaly low of −35 mGal amplitude, one of the largest magnitude gravity anomalies associated with a terrestrial impact structure. Superimposed on the gravity low is a concentric ring-shaped high, ~45 km in diameter, that coincides with uplifted ...
