WebCrater rays are formed during a cratering event as target material is ballistically ejected to distances of many crater radii forming narrow, generally high albedo, approximately linear features extending out- ward from the crater. The nature of crater rays was examined for the lunar crater Copernicus using new WebThe calibration for this method, which allows converting crater densities (i.e., crater sizefrequency distributions ) to absolute model ages, is based on returned Apollo and Luna samples that can be linked to a geological unit (e.g., a lava flow) or an impact basin/crater for which absolute radiometric or cosmic ray exposure (CRE) ages have been determined … Web1 Introduction. Establishing the lunar crater chronology (i.e., surface age vs. crater density) relies on the lunar production function (PF; the formation rate of craters as a function of crater diameters), because a PF enables the conversion of a measured crater size-frequency distribution (SFD) to a reference crater density (e.g., N(1), the cumulative density of … citi thankyou rewards catalog
