TLDR
In this article, a theoretical treatment of the ascent, emplacement, and eruption of magma on Mars is presented, showing that the lower gravity, fluid convective motions and crystal settling processes driven by positive and negative buoyancy forces, as well as overall diapiric ascent rates, will be slower on Mars than on Earth, permitting larger diapirs to ascend to shallower depths.Abstract:
We present a theoretical treatment of the ascent, emplacement, and eruption of magma on Mars. Because of the lower gravity, fluid convective motions and crystal settling processes driven by positive and negative buoyancy forces, as well as overall diapiric ascent rates, will be slower on Mars than on Earth, permitting larger diapirs to ascend to shallower depths. Martian environmental conditions operate to modulate the various eruption styles and the morphology and morphometry of resulting landforms, providing new insight into several volcanological problems.read more

TL;DR: The Mars Orbiter Laser Altimeter (MOLA) has been used to measure the topography, surface roughness, and 1.064-μm reflectivity of Mars and the heights of volatile and dust clouds as mentioned in this paper.

TL;DR: The HiRISE camera as mentioned in this paper provides detailed images (0.25 to 1.3 m/pixel) covering ∼1% of the Martian surface during the 2-year Primary Science Phase (PSP) beginning November 2006.

TL;DR: The Context Camera (CTX) on the Mars Reconnaissance Orbiter (MRO) is a Facility Instrument (i.e., government-furnished equipment operated by a science team not responsible for design and fabrication) designed, built, and operated by Malin Space Science Systems and the MRO Mars Color Imager team (MARCI) as mentioned in this paper.

Mars Global Surveyor Mars Orbiter Camera: Interplanetary cruise through primary mission
TL;DR: More than three years of high-resolution (1.5-20 m/pixel) photographic observations of the surface of Mars have dramatically changed our view of that planet as mentioned in this paper, and some of the most important observations and interpretations derived therefrom are that much of Mars, at least to depths of several kilometers, is layered; substantial portions of the planet has experienced burial and subsequent exhumation; layered and massive units, many kilometers thick, appear to reflect an ancient period of large-scale erosion and deposition within what are now the ancient heavily cratered regions of Mars; and

TL;DR: The Noachian period was characterized by high rates of impact, valley formation, weathering, and erosion all dropped precipitously but volcanism continued at a relatively high average rate throughout the Hesperian, resulting in the resurfacing of at least 30% of the planet.

Turbulent gravitational convection from maintained and instantaneous sources
TL;DR: In this article, the authors developed a theory of convection from maintained and instantaneous sources of buoyancy, using methods which are applicable to stratified body fluids with any variation of density with height; detailed solutions have been presented for the case of a stably stratified fluid with a linear density gradient.

Properties of some common igneous rocks and their melts at high temperatures
TL;DR: The properties of four igneous rocks (a tholeiitic and an alkali-olivine basalt, an andesite, and a rhyolite) and a synthetic lunar sample have been determined at atmospheric pressure over a range of temperatures including their melting interval as discussed by the authors.

The dynamics of bubble formation and growth in magmas: A review and analysis
TL;DR: In this article, a numerical method has been developed to determine bubble growth rates during volcanic eruptions of basaltic and rhyolitic tephras, and the numerical solutions consider both diffusional and decompressional growth and the effects of magma ascent rates (0-400 cm s−1), magma viscosity (102 to 108 poise), gas solubility, gas content (0.25-5%), and gas diffusivity (10−6 to 10−9 cm2 s− 1) on growth rates.

Water on Mars
TL;DR: In this paper, the amount of water outgassed from Mars by impact erosion and hydrodynamic escape is estimated to be between 6 to 160 m. The two sets of estimates may be reconciled if early in its history, Mars lost part of its atmosphere.
