Morphology and Mechanics of Terraces in Lunar CratersThe morphology and morphometry of terrace provide information on the mechanical conditions of failure and enlargement of impact craters. A simple, perfect plasticity model for terrace formation was proposed, but the preliminary terrace width measurements used to support the model were insufficient to provide a rigorous test. Lunar crater terraces were studied morphometrically. Roughly 1,000 terraces in 53 fresh lunar craters were measured using Apollo and Lunar Orbiter vertical stereo photography. Terrace widths and their order inward from the rim were measured along eight equally spaced radials in each crater. A list of the craters including rim diameters and geologic data is presented.
