Foelsche is a partly buried
astrobleme), the eroded remnant of a former impact crater. It is situated about 85 km southeast of Borroloola in the Northern Territory, Australia, and named after the nearby Foelsche River. Although little of it is exposed at the surface, and no crater shaped topography is evident, the circular nature of the feature is obvious on aeromagnetic images, a factor that led to its discovery.[1][2]
Description
The impact occurred into flat-lying
The age of Foelsche is not well constrained, but it must be younger than the Mesoproterozoic target rocks and older than the Neoproterozoic rocks that partly fill the crater; it has been argued that the age is most likely Neoproterozoic because it appears that the crater was covered by sediments soon after the impact event.[1]
