On the Origin of Central Peaks in the Crater Formations Filled by Melt After Impacts

Abstract

An attempt is made at explaining the successive origin of the central peaks and terrace ring-wall in the crater formations filled with melt after impacts.

On the Origin of Central Peaks in the Crater Formations Filled by Melt After Impacts

“…The volume of a solid crystallized basalt is 3-10% smaller than the volume of the original melt. In the solidifying volumes of spherical shapes large cavities are formed in the centre (Kopecky, 1971).…”

“…Possible relations between meteorite impact and igneous petrogenesis were discussed also by French (1970).…”
