Widespread sedimentary rocks on Mars preserve evidence of surface conditions different from the modern cold and dry environment, although it is unknown how long conditions favorable to deposition persisted. We used 1-meter stereo topographic maps to demonstrate the presence of rhythmic bedding at several outcrops in the Arabia Terra region. Repeating beds are ∼10 meters thick, and one site contains hundreds of meters of strata bundled into larger units at a ∼10:1 thickness ratio. This… 

Occurrence and origin of rhythmic sedimentary rocks on Mars

Sedimentary rocks preserved on the surface of Mars represent a natural archive of past climate conditions. Although the details of their formation often remain poorly constrained, the recent

The Sedimentary Rock Record of Mars: Distribution, Origins, and Global Stratigraphy

The last decade of Mars exploration produced a series of discoveries that provide compelling evidence for the existence of sedimentary rocks on Mars. Previously, Mars was regarded principally as a

Mars sedimentary geology: key concepts and outstanding questions.

The contents of this white paper represent the most significant findings of the First International Conference on Mars Sedimentology and Stratigraphy, and focus on seven key questions for future investigation by the sedimentary geology community.

Paleoclimate of Mars as captured by the stratigraphic record in Gale Crater

A kilometers‐thick sedimentary sequence in Gale Crater exhibits stratigraphic changes in lithology that are consistent with transitions in aqueous and climatic conditions purported to be global in

High-Resolution Stratigraphy of the Mars North Polar Layered Deposits

The Mars north polar layered deposits (NPLD) consist primarily of water ice and dust, and represent the bulk of the north polar cap [Byrne, 2009]. The NPLD likely hold the most extensive record of

Recognition of Sedimentary Rock Occurrences in Satellite and Aerial Images of Other Worlds - Insights from Mars

Global coverage at 0.25–6 m/pixel, and observations from the Curiosity rover in Gale crater, expand the ability to recognize Martian sedimentary rocks, and it is likely that Mars likely has much more sedimentary rock than previously recognized.

Quantitative bounds on morphodynamics and implications for reading the sedimentary record.

It is shown that the advection length for settling sediment sets bounds on the scales over which internal landscape dynamics operate that provide a universal palaeohydraulic reconstruction tool on planetary surfaces and allow for quantitative identification of depositional systems that may preserve tectonic, climatic and anthropogenic signals.

Sequence of infilling events in Gale Crater, Mars: Results from morphology, stratigraphy, and mineralogy

Gale Crater is filled by sedimentary deposits including a mound of layered deposits, Aeolis Mons. Using orbital data, we mapped the crater infillings and measured their geometry to determine their

Sedimentary rocks of early Mars.

Affinity for impact craters suggests dominance of lacustrine deposition; alternatively, the materials were deposited in a dry, subaerial setting in which atmospheric density, and variations thereof mimic a subaqueous depositional environment.

Martian sedimentary rock stratigraphy: Outcrops and interbedded craters of northwest Sinus Meridiani and southwest Arabia Terra

Layers in the upper martian crust record a complex history of deposition and erosion. We examined a region between 2°–9°N, 1°–8°W and found that light‐toned, layered, sedimentary rocks in northwest

Orbital forcing of the martian polar layered deposits

A correlation exists between ice-layer radiance as a function of depth and the insolation variations in summer at the martian north pole, similar to what has been shown for palaeoclimate studies of the Earth.

Recent ice ages on Mars

Evidence is shown that dusty, water-ice-rich mantling deposits on Mars formed during a geologically recent ice age that occurred from about 2.1 to 0.4 Myr ago, a key pacemaker of ice ages on the Earth.
