[1] Airborne Visible/Near‐Infrared Imaging Spectrometer (AVIRIS) data acquired over the Ka’u Desert are atmospherically corrected to ground reflectance and used to identify the mineralogic components of relatively young basaltic materials, including 250–700 and 200–400 year old lava flows, 1971 and 1974 flows, ash deposits, and solfatara incrustations. To provide context, a geologic surface uni...

Introduction. Deuteronilus Mensae is a ~1000 km wide area along the highland/lowland dichotomy boundary in the northern mid-latitudes of Mars. In this region, features diagnostic of Martian 'fretted' terrain are observed, including lobate debris aprons, lineated valley fill, and concentric crater fill [1-5]. South of Deuteronilus Mensae are the rugged cratered highlands of Arabia Terra and nort...

Introduction: We applied multiple endmember demixing [1, 2] to Thermal Emission Spectrometer (TES) data to determine the composition of geologic units in the Valles Marineris (VM), Mars. The goal is to map the compositions of VM dark deposits [3] and layered units of the walls and interior deposits [4-6]. Background: The Valles Marineris (Fig. 1) offer 3-D views into the Martian crust to depths...

Introduction Geologic mapping of planetary surfaces provides information on the nature, sequence, and distribution of material units, from which one can assemble a geologic history [1]. With this goal in mind, the Galileo SSI camera acquired an important dataset of images of Europa at a resolution suitable for geologic reconnaissance and mapping. We performed mapping and analysis of pole-to-pol...

Abstract The Schrödinger basin on the south polar lunar far side has been highlighted as a promising target for future exploration. This report provides high-resolution geologic map in southwest peak-ring (SWPR) area of basin, emphasizing structural features and detailed mapping exposed outcrops within peak ring. Outcrops are correlated with mineralogical data from Moon Mineralogical Mapper ins...

Semantic Web technologies bring innovative ideas to computer applications in geoscience. As an essential part of the Semantic Web, ontologies are increasingly discussed in the geoscience community, in which geologic time scale is one of the topics that have received the most discussion and practices. This paper aims to carry out a review of the recent progress on geologic time ontologies, discu...
