Lockne is a meteorite crater, located approximately 21km (13miles) south of the city of Östersund in northern Sweden.[1] It has been suggested that it is a doublet with the nearby smaller Målingen Crater, 16km (10miles) apart.[2] Computer simulations suggest that the asteroid that created the Lockne crater was some 600m (2,000feet) in diameter, and the one that carved out Målingen crater was about 250m (820feet) across.[2]
It is 7.5km (04.7miles) in diameter and the age is estimated, based on accompanying chitinozoan microfossils, to be 458 million years (Late Ordovician).[1] The crater is exposed at the surface. Its fossils, typical of shallow marine environments, show it to be a marine target impact event.
