TL;DR: In this article, the authors show that the pressure at which degassing occurs, that is the atmospheric pressure in most sensible cases, has a prime influence on the composition of subaerial volcanic gases on planets: high surface pressure produces N 2 -and CO 2 -rich and dry volcanic gases, while low pressure promotes sulfur-rich gases.

TL;DR: The Gangotri leucogranite is the western end of the Badrinath granite, one of the largest bodies of the High Himalayan Leucogrite belt (HHL) as discussed by the authors.

TL;DR: In this article, an experimental and petrological study aimed at estimating the pre-eruptive conditions of a Holocene dacitic lava from Volcan San Pedro (36°S, Chilean Andes).

TL;DR: In this article, the authors find that the martian mantle contains at least 3-4 times as much sulfur as its terrestrial counterpart, yielding basaltic melts richer in sulfur than those on Earth.

TL;DR: In this paper, the near-liquidus crystallization of a high-K basalt (PST-9 golden pumice) from the present-day activity of Stromboli (Aeolian Islands, Italy) has been experimentally investigated between 1050 and 1175°C, at pressures from 50 to 400 MPa, for melt H2O concentrations between 1·2 and 5·5 wt % and {Delta}NNO ranging from −0·07 to +2·32.
