Silty clays were dominant sediments in both the cores. The inventory of water and carbon dioxide reservoirs on Mars are important clues for understanding the geological, climatic and potentially exobiological evolution of the planet. New Zealand Journal of Marine and Freshwater Research v. Major environmental shifts took place during the 20th century, when the population around Cadiz Bay increased exponentially. .

An associated specimen of Carcharodon Angustidens Chondrichthyes, Lamnidae from the Late Oligocene of New Zealand, with comments on Carcharodon interrelationships. This increase of seasonality can signal a summer breakdown of coastal upwelling and of meridional Trade Winds which correlates with the reduced supply of northwest Saharan dust.
This cache would be left either on the ground or on the rover where it could be recovered by a possible future sample return mission.

We report lithological descriptions of the sediments and extensive mineralogical and geochemical analyses. There is also no correlation between the mineralogical composition and the geographical location recognizable. As Titanium Ti is restricted to the terrigenous phase in sediments and is inert to diagenetic processes Calvert and Pedersen, 2007 , we utilized Ti to nor- malize other chemical elements for the terrigenous fraction.
