Structural architecture and deformation history of Tempe Terra, Mars

Abstract

Tempe Terra is a structurally complex region situated at the northeast edge of the Tharsis Rise volcano-tectonic province (Figure 1). Crustal stresses associated with the development of the Tharsis Rise resulted in the formation of radial extensional features and concentric shortening features surrounding Tharsis (Figure 1) (Anderson et al., 2001). Despite decades of research into various aspects of the Tharsis Rise (e.g.,

Structural Architecture and Deformation History of Tempe Terra, Mars

“…The catalog of mapped structural features produced as part of this work is available for download in shapefile format from Zenodo (Orlov, 2022). The crater database created by Lagain et al (2021) which we used in our buffered crater counting is available to download from Zenodo (Marmo & Lagain, 2020).…”

“…We also generated regional fault maps to aid qualitative analysis of the structural architecture and spatial trends in tectonic activity through time. The resulting comprehensive inventory of structures is available in GIS format (Orlov, 2022). This work focuses on the location and timing of tectonic structures in Tempe Terra but lays important groundwork for further study of Tharsis.…”
