[1] The High Resolution Stereo Color camera (HRSC) data over Hesperia Planum and its surroundings reveal important details of geologic episodes and water-related processes in this region. (1) The… (More)
Impact craters are not always circular; sometimes their rims are composed of several straight segments. Such polygonal impact craters (PICs) are controlled by pre-existing target structures, mainly… (More)
[1] Geologic evolution of the western portion of Promethei Terra (40–50°S, 90–105°E) consists of two major episodes. The first was the formation of a late Noachian–early Hesperian volcanic province.… (More)
Abstract Four prominent fluvial systems, Dao, Niger, and Harmakhis Valles, and a system of smaller channels between Niger and Harmakhis Valles characterize a wide topographic trough that connects… (More)
[1] We examine a narrow latitudinal band (60°N–70°N) on Mars to place constraints on the seasonally averaged velocity Q of boulder movements over patterned ground. These latitudes comprise a region… (More)

Abstract The eastern Hellas basin rim has been highly modified by a multitude of both volcanic and fluvial processes. It is covered by a large part of the Circum-Hellas Volcanic Province, consisting… (More)
Introduction: Water on Mars is already a proven fact [e.g. 1]. There are also many studies on ancient lacustrine features [e.g. 2-4]. However, there is still a lot to learn and discover of the… (More)
Geometallurgical modelling of an orebody provides benefits to a mine by gaining a better understanding of the ore characteristics and how these affect the performance of the concentrator. With this… (More)
Introduction: This study discusses the characteristics of an enigmatic ~25 km crater (Fig. 1a), located at 36,0Nº/351,8Eº, in Arabia Terra; highland side of the dichotomy boundary. It has roughly… (More)
