Impact Melt on Lunar Crater Rims

Bernard Ray Hawke, James W. Head III

Open publisher page 93 citations

Abstract

The reported study had the objective to determine the origin, distribution, and modes of occurrence of lava-like deposits and the factors responsible for their emplacement. Lava-like deposits around a large number of lunar craters were investigated in order to obtain information on the variation in morphology and the distribution as a function of crater size. The results should have bearing on lunar and terrestrial impact cratering processes and the provenance of the abundant impact melt rocks in the lunar sample collection. Attention is given to the size range of craters with exterior melt deposits, the morphology of deposits as a function of crater size, the factors responsible for melt deposit asymmetry, the time of melt emplacement, and a model for the formation of impact melt deposits on crater rims.
