  • Crustal melting may play a fundamental role in orogenic processes, but quantifying crustal melt remains difficult. Here, the authors combine pressure-temperature paths, electrical conductivity and geophysical data to elucidate the melting conditions in Tibet since the Miocene.

  • The Moon was once thought to be depleted in volatile elements. Analyses of the carbon contents of lunar volcanic glasses reveal that carbon monoxide degassing could have produced the fire-fountain eruptions from which these glasses were formed.

  • Direct evidence for the role of volatiles in magmatic ore formation has been elusive. Magma degassing at Merapi volcano in Indonesia is found to be directly linked to the selective leaching of metals from sulphide melts that ultimately form ore deposits.

  • A coupled chemical–physical model of conduit flow shows that the oxidation state of an ascending magma is strongly dependent on both the composition and amount of gas in the reservoir.

  • A study of cerium in zircon minerals has allowed an assessment of the redox conditions that prevailed when Earth's earliest magmas formed. The results suggest that the mantle became oxidized sooner than had been thought. See Letter p.79

  • The cause of episodes of unrest at caldera volcanoes is often unclear. Analysis of the sulfur composition of gas emissions at Campi Flegrei in Italy suggests a magmatic origin of the recent unrest at this hazardous caldera.

  • Indonesia is the country with the most active volcanoes, several of which are renowned for climate-changing eruptions. Here the authors show a rather moderate sulfur emissions budget and reinforce the idea that sulfur-rich eruptions reflect long-term accumulation of volatiles in the reservoirs.

  • The redox state of volcanic gases and melts can become decoupled during magma ascent, according to observations of gas emissions from KÄ«lauea’s lava lake, Hawaii. Cooling of fast-rising bubbles changes the abundance of redox-sensitive gas species.

  • Andesites are a large part of the continental crust, but their origins remain enigmatic. Here, the authors update older mixing models via high-temperature experiments and thermal calculations, showing that homogeneous mixtures are only possible with high mafic fractions and during high magma flux.

  • Five major explosive volcanic pulses in the Main Ethiopian Rift took place in the last four million years with intensity and magnitude declining over time, based on stratigraphic and geochronology data of volcanic units.
