Eridania Lake
Eridania Lake is a hypothesized ancient lake on Mars with a surface area of roughly 1.1 million square kilometers. It is located at the source of the Ma'adim Vallis outflow channel and extends into Eridania quadrangle and the Phaethontis quadrangle. As Eridania Lake dried out in the late Noachian epoch it divided into a series of smaller lakes.

PIA22059 fig1eridaniadepthslabeled.jpg, Features around Eridania Sea labeled Makeup Later research with CRISM found thick deposits, greater than 400 meters thick, that contained the minerals saponite, talc-saponite, Fe-rich mica (for example, glauconite- nontronite), Fe- and Mg-serpentine, Mg-Fe-Ca-carbonate and probable Fe- sulphide. The Fe-sulphide probably formed in deep water from water heated by volcanoes. Such a process, classified as hydrothermal may have been a pla ...

Eridania Planitia
Eridania Planitia is a plain located in the southern highlands of Mars. It borders the Hellas basin to the west, Promethei Terra to the south, and the massive shield volcano Hesperia Planum to the north. The name Eridania Planitia was approved by the International Astronomical Union The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and developmen ... (IAU) on 22 September 2010; it is named after the closest classical albedo feature. Characteristics As with much of the Martian southern highlands, Eridania Planitia is ancient, with an estimated age of roughly 3.7–4 billion years old. However, subregions within the plains are younger, with a large depression (informally named the Morpheos basin) likely forming within a period spanning between 3.52 and 3.67 billion years ago. Additionally, Erid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
