Throughout the recorded history of Mars, liquid water has distinctly shaped its landscape,
including the prominent circum-Chryse and the northwestern slope valleys outflow channel …

The undulating, warped, and densely fractured surfaces of highland regions east of Valles
Marineris (located north of the eastern Aureum Chaos, east of the Hydraotes Chaos, and …

The paradigm of an ancient warm, wet, and dynamically active Mars, which transitioned into
a cold, dry, and internally dead planet, has persisted up until recently despite published …

The Gamma Ray Spectrometer (Mars Odyssey spacecraft) has revealed elemental
distributions of potassium (K), thorium (Th), and iron (Fe) on Mars that require fractionation of …

The proposed existence of magnetic lineations in the Terra Cimmeria and Terra Sirenum
regions of Mars was initially explained by Earth-like sea-floor spreading. Here we argue …

Noachian layered materials are pervasively exposed throughout the highlands of Mars. The
layered deposits, in places many kilometers thick, exhibit impact craters of diverse …

A number of tectonic structures have been located at the Thaumasia Plateau, Daedalia
Planum and Aonia Terra, Mars. They include isolated folds with axial traces up to 200 km …

A circular albedo feature in the Arabia Terra province was first hypothesized as an ancient
impact basin using Viking-era information. To test this unpublished hypothesis, we have …

The Moon has an anorthositic primordial continental crust. Recently anorthosite has also
been discovered on the Martian surface. Although the occurrence of anorthosite is observed …

In this paper, we show that the complex geological evolution of Valles Marineris, Mars, has
been highly influenced by the manifestation of magmatism (eg, possible plume activity). This …
