Discerning Secondary Impacts from Primary Ones
Figure 1: He wrote the book A Fortunate Encounter During the poster session at #LPSC2017, I was surprised and delighted that Jay Melosh stopped to discuss my poster on doublet craters . Not only had I cited some of his papers in my work, but he also "wrote the book" on Impact Cratering (no, really !). Dr. Melosh was genuinely interested, and also pleased to see that my co-author (and graduate advisor) was Ron Fevig , a former student of his at the Lunar and Planetary Laboratory at U of A. After examining the images of potential doublets from my survey area, Figure 2: Doublet crater on Ceres he noted that the ones I had identified as "highly eroded" (see figure 2) may not be that eroded, but were possibly secondary craters, since their rims were irregular rather than cleanly circular. He also referred me to his book for a good description. Refining Crater Identification Criteria Moving into the next phase of my research, I need to be capable of ...
