Background: Promethei Lingula, a part of Mars’ south polar plateau, Planum Australe, is made up of south polar layered deposits (SPLD) and includes three broad, deep canyons trending perpendicular to the plateau margin and several spiral troughs concentric to the plateau. Two of the canyons, Promethei and Ultimum Chasmata, expose substrate beneath SPLD, and the other canyon displays a variety of erosional landforms within SPLD, including curvilinear, longitudinal grooves (Australe 
New insights into the Late Amazonian zonal shrinkage of the martian south polar plateau
The martian south polar plateau, Planum Australe, comprises the largest known water–ice surface deposit on the planet. Here, we present evidence for an episode of extensive polar plateau retreatExpand
“Unconformity-Bounded” Stratigraphic Units in the South Polar Layered Deposits (Promethei Lingula, Mars)
We conducted a stratigraphic analysis of the South Polar Layered Deposits (SPLDs) in Promethei Lingula (PL, Mars) based on the identification of regional unconformities at visible and radarExpand
The construction of Chasma Boreale on Mars
New data from the Mars Reconnaissance Orbiter are used to show that Chasma Boreale is instead a long-lived, complex feature resulting primarily from non-uniform accumulation of the NPLD, and that topography existing before the N PLD began accumulating influenced successive episodes of deposition and erosion, resulting in most of the present-day topography.

North polar region of Mars: Advances in stratigraphy, structure, and erosional modification
We have remapped the geology of the north polar plateau on Mars, Planum Boreum, and the surrounding plains of Vastitas Borealis using altimetry and image data along with thematic maps resulting fromExpand
North polar trough formation due to in-situ erosion as a source of young ice in mid-latitudinal mantles on Mars
The retention of the spiral pattern in surface and subsurface troughs is consistent with the megastructure’s stabilization before its partial burial, and could provide a valuable source of near-surface, clean ice for future human exploration. Expand
Martian South Polar Layered Deposit stratigraphy and implications for accumulation history
[1] We examine the stratigraphy of the Martian South Polar Layered Deposits (SPLD) exposed on scarp walls throughout the deposit using THEMIS visible (17 m/pxl) images from the Mars OdysseyExpand
Planum Boreum basal unit topography, Mars: Irregularities and insights from SHARAD
Shallow Radar investigations of Planum Boreum, Mars' “basal unit” (BU) deposit have revealed multiple reentrants, morphologic irregularities, and thickness trends that differ from those of theExpand
Regional stratigraphy of the south polar layered deposits (Promethei Lingula, Mars): “Discontinuity-bounded” units in images and radargrams
Abstract The Mars South Polar Layered Deposits (SPLD) are the result of depositional and erosional events, which are marked by different stratigraphic sequences and erosional surfaces. ToExpand

Physical modelling of large-scale deformational systems in the South Polar Layered Deposits (Promethei Lingula, Mars): new geological constraints and climatic implications
Abstract Deformation systems (DSs) locally affect the South Polar Layered Deposits (SPLDs) along the margins of the Promethei Lingula ice sheet (part of the southern Martian ice-dome). One example isExpand


The Role of Eolian Processes in Forming Surface Features of the Martian Polar Layered Deposits
Abstract The major topographic features of the martian polar layered deposits include the conspicuous spiral troughs, subtle undulations, broad reentrants (chasma), steep, arcuate scarps, and duneExpand
Geologic history of the polar regions of Mars based on Mars Global surveyor data. II. Amazonian period
Based on Mars Orbiter Laser Altimeter (MOLA) and Mars Orbiter Camera (MOC) observations of Amazonian polar layered deposits' (PLD) morphology, composition, and thickness, we conclude that the PLDsExpand
Geologic History of the Polar Regions of Mars Based on Mars Global Surveyor Data: I. Noachian and Hesperian Periods
During the Noachian Period, the south polar region of Mars underwent intense cratering, construction of three groups of volcanoes, widespread contractional deformation, resurfacing of low areas, andExpand
Eolian controlled modification of the martian south polar layered deposits

Polar deposits of Mars
Layered deposits unique to the poles of Mars indicate long-term winter deposition of ice and sediment modulated by periodic climate change. The layered deposits contain at least two kinds ofExpand
Internal structure of the Martian south polar layered deposits
[1] We investigate the three-dimensional (3-D) stratigraphic structure of the south polar layered deposits (SPLD) on Mars. Prominent bench-forming layers exposed on SPLD scarps were observed andExpand
Origin of the stepped topography of the Martian poles
Abstract The circumpolar stepped topography observed within the Martian polar regions can have originated from one of a limited number of processes, including (i) erosion of resistant layers, (ii)Expand
Surface Ages and Resurfacing Rates of the Polar Layered Deposits on Mars
Interpretation of the polar stratigraphy of Mars in terms of global climate changes is complicated by the significant difference in surface ages between the north and south polar layered terrainsExpand
