MOLA Topography of Alba Patera Flow Field
Abstract
As part of an ongoing study of planetary lava flows, regridded MOLA data is being used to examine the topography of an Alba Patera flow field. Alba Patera, the largest known volcanic edifice (when surface area alone is considered), presents the opportunity to study a variety of Martian lava flow morphologies, due to the complexity, as well as the number and length, of flows present. Previous morphometric studies, based on flow maps derived from Viking imagery, revealed similarities between terrestrial basaltic flow fields and those identified on Alba Patera. These studies are of limited value, however, as adequate topographic information was lacking. The current study addresses this limitation by using regridded MOLA data to generate flow field topographic maps and cross-sectional profiles. These detailed profiles are compared to differential GPS measurements of the Carrizozo lava flow in New Mexico. Results of the Mars study, and terrestrial analog comparisons, will be presented.
