| Description | Geomorphic mapping at 1:500,000 scale within three quadrangles in Margaritifer Terra, Mars, is nearing completion (Fig. 1) [e.g., 1 - 4]. This region was previously studied [5-9] because of the combination of geomorphic processes that have shaped its surface, and the current mapping has revealed details that were not visible in Viking Orbiter images used by those previous studies. The large Uzboi- Holden-Ladon-Margaritifer megaoutflow system has shaped the western part of Margaritifer Terra (Fig. 1), and flow in the Samara and Paran -Loire valley systems merged with UHLM in MTM -15022 [3]. The area in MTMs -20022 and -20017 has also been shaped by many impact craters, including an outer ring of Ladon basin and the relatively young Jones crater. Fluvial erosion associated with Loire Valles and Samara Valles and their tributaries has influenced much of the surface, and many areas are covered by resurfacing deposits (possibly fluvial, volcanic, and/or aeolian). MTMs -20022 and -20017 include Jones crater, the confluence of Himera Valles and Samara Valles, and a significant portion of Loire Valles (Fig. 1). One of the main objectives of this mapping is to determine the relative timing of fluvial activity and impact cratering, specifically the impact that created Jones. |
