Calorimetric properties of magmas
, 2010 International audience; Magmatic and volcanic processes are strongly controlled by the physical and thermodynamic properties of silicate melts. Recently it has been recognized that the way in which the magma crosses the so-called "glass transition" boundary can determine whether a quite degassing, through preferential pathways, or a catastrophic ...

Convective shutdown in the atmospheres of lava worlds [PDF]
Atmospheric energy transport is central to the cooling of primordial magma oceans. Theoretical studies of atmospheres on lava planets have assumed that convection is the only process involved in setting the atmospheric temperature structure. This significantly influences the ability for a magma ocean to cool.

Regional controls on magma ascent and storage in volcanic arcs
, 2014 Understanding the controls for magma ascent and storage depth is important for volcanic hazard assessment. Regional differences in the depths of magma storage between volcanic arcs suggest that the settings of subduction zones and of overriding plates ...

Rates of magma transfer in the crust: Insights into magma reservoir recharge and pluton growth
, 2014 Plutons have long been viewed as crystallized remnants of large magma reservoirs, a concept now challenged by high-precision geochronological data coupled with thermal models.

Ocean Circulation on Tide-locked Lava Worlds, Part II: Scalings [PDF]
arXivOn tidally locked lava planets, magma ocean can form on the permanent dayside. The circulation of the magma ocean can be driven by stellar radiation and atmospheric winds. The strength of ocean circulation and the depth of the magma ocean depend on external forcings and the dominant balance of the momentum equation.

Mestre's Finite Field Method for Searching Elliptic Curves with High Ranks
Journal of New TheoryThe theory of elliptic curves is one of the popular topics of recent times with its unsolved problems and interesting conjectures. In 1922, Mordell proved that the group of $\mathbb{Q}$-rational points on an elliptic curve is finitely generated ...

The role of discontinuous magma inputs in felsic magma and ore generation
Ore Geology Reviews, 2007 For a long time, granites have been considered as passive bodies ascending under intrinsic negative density and viscosity contrasts with their host rocks. Chemical variations within a granitic body resulted from in situ differentiation and crystal fractionation.
