Clinoforms are inclined and normally basinward-dipping horizons developed over a range
of spatial and temporal scales in both siliciclastic and carbonatic systems. The study of …

The climate of early Mars remains a topic of intense debate. Ancient terrains preserve
landscapes consistent with stream channels, lake basins and possibly even oceans, and …

Establishing the presence and state of organic matter, including its possible biosignatures,
in martian materials has been an elusive quest, despite limited reports of the existence of …

Clay minerals provide indicators of the evolution of aqueous conditions and possible
habitats for life on ancient Mars. Analyses by the Mars Science Laboratory rover Curiosity …

Reconstruction of the palaeoenvironmental context of Martian sedimentary rocks is central to
studies of ancient Martian habitability and regional palaeoclimate history. This paper reports …

Analyses by the CheMin X-ray diffraction instrument on Mars Science Laboratory show that
gypsum, bassanite, and anhydrite are common minerals at Gale crater. Warm conditions (∼ …

The Martian surface is cold, dry, exposed to biologically harmful radiation and apparently
barren today. Nevertheless, there is clear geological evidence for warmer, wetter intervals in …

Abstract Mars Science Laboratory (MSL) Curiosity rover data are used to describe the
morphology of desiccation cracks observed in ancient lacustrine strata at Gale crater, Mars …

The Curiosity rover has documented lacustrine sediments at Gale Crater, but how liquid
water became physically stable on the early Martian surface is a matter of significant debate …

We measured sand sizes and shapes on diverse eolian bedforms in Gale crater to help
constrain models of eolian sediment transport on Mars. All grains are subangular to rounded …
