These water bodies range from large oceans in the Noachian-Early Hesperian, to a minor sea in the Late Hesperian, and reduced lakes during the Amazonian. Assuming that the search for life is directly linked to the search for water, the possible biological history of Mars must have been largely influenced by the endogenetically-driven hydrogeological cycles. In consequence, terrestrial bi- ological and environmental analogues can now be placed in context with the model proposed, so contributing to draw a general approach for the history of life on Mars. -

New and revised geographic and geologic terminologies assist with effectively discussing the various features of this region. We identify 7 geologic units making up Planum Boreum and at least 3 for the circumpolar plains, which collectively span the entire Amazonian Period. The Planum Boreum units resolve at least 6 distinct depositional and 5 erosional episodes. The first major stage of activity includes the Early Amazonian (∼3 to 1 Ga) deposition (and subsequent erosion) of the thick (locally exceeding 1000 m) and evenly- layered Rupes Tenuis unit (ABrt), which ultimately formed approximately half of the base of Planum Boreum. As previously suggested, this unit may be sourced by materials derived from the nearby Scandia region, and we interpret that it may correlate with the deposits that regionally underlie pedestal craters in the surrounding lowland plains. -

Global Spectral Classification of Martian Low-Albedo Regions with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) Data A
JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 112, E02004, doi:10.1029/2006JE002726, 2007 Global spectral classification of Martian low-albedo regions with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) data A. Deanne Rogers,1 Joshua L. Bandfield,2 and Philip R. Christensen2 Received 4 April 2006; revised 12 August 2006; accepted 13 September 2006; published 14 February 2007. [1] Martian low-albedo surfaces (defined here as surfaces with Mars Global Surveyor Thermal Emission Spectrometer (MGS-TES) albedo values 0.15) were reexamined for regional variations in spectral response. Low-albedo regions exhibit spatially coherent variations in spectral character, which in this work are grouped into 11 representative spectral shapes. The use of these spectral shapes in modeling global surface emissivity results in refined distributions of previously determined global spectral unit types (Surface Types 1 and 2). Pure Type 2 surfaces are less extensive than previously thought, and are mostly confined to the northern lowlands. Regional-scale spectral variations are present within areas previously mapped as Surface Type 1 or as a mixture of the two surface types, suggesting variations in mineral abundance among basaltic units. For example, Syrtis Major, which was the Surface Type 1 type locality, is spectrally distinct from terrains that were also previously mapped as Type 1. A spectral difference also exists between southern and northern Acidalia Planitia, which may be due in part to a small amount of dust cover in southern Acidalia. Groups of these spectral shapes can be averaged to produce spectra that are similar to Surface Types 1 and 2, indicating that the originally derived surface types are representative of the average of all low-albedo regions. -
