Title

Determining outlines of basalt shield and other planetary craterforms

Abstract

The shape of a craterform is determined by the process from which it was formed. Some craterforms, like Ionian paterae, are the result of uncertain processes, so their shape can be compared to the geometry of craters with known origins. This comparison can give insight into the method of formation of these yet-unexplained craterforms. Statistical analysis using Z-R shape functions has been performed, but other methods may give more insight. Starting with terrestrial basalt shield calderas, which are easy to see from satellite images and have well-known origins, we obtained several sets of measurements of each craterform to obtain the most accurate outline. Currently, five basalt shield craters have been mapped as I start gathering a comprehensive dataset for terrestrial basalt shield and ash-flow calderas, Martian calderas, lunar impact craters, and Ionian paterae.
