Short summary
This study examines how trace elements are distributed between melt and crystals during dacite crystallization (675–775 °C, 200 MPa) using a two-step experiment combining long-duration runs and a mineral trap technique. Residual melts were effectively separated and analysed. LA-ICP-MS (laser ablation inductively coupled plasma mass spectroscopy) data for elements like P, Y, Zr, Nb, Cs, Ce, Yb, and U reveal that, while Cs and U stay incompatible, other elements are affected by the type of crystallizing minerals.

We studied the exchange of chemical elements by diffusion between magmas of tephritic and phonolitic composition from the Canary Islands, performing experiments at high pressure and high temperature with different amounts of added water. Our results characterize the way water and temperature affect the diffusion process, and we also find unexpectedly high mobility of aluminium, which may be related to its variable chemical bonding in highly alkaline melts.

The structure of beryl has been a topic of research for decades but is still not entirely understood. This especially applies to substitutions by Fe ions and the occupation of the channels of beryl by H2O and alkalis. The growing amount of studies makes it difficult to gain an overview on these topics. Therefore, this article reviews the current consensus and debates found in the literature.

The new spectroscopic method, based on the syncrotron radiation, allows for determination of Fe oxidation state in tiny objects or in heterogeneous samples. This technique is expected to be an important tool in geosciences unraveling redox conditions in rocks and magmas as well as in material sciences providing constraints on material properties.

Short summary
Volcanoes on Earth are divided into monogenetic and composite volcanoes based on edifice shape. Currently the evolution from monogenetic to composite volcanoes is poorly understood. There are two distinct magma chambers, with a deeper region at the Moho and a shallow mid-crustal zone in the Wulanhada Volcanic Field. The crustal magma chamber represents a snapshot of transition from monogenetic to composite volcanoes, which experience more complex magma processes than magma stored in the Moho.

Short summary
Lascar volcano, located in northern Chile, is among the most active volcanoes of the Andes. Its activity culminated in the last major explosive eruption in April 1993. We carried out experiments at high temperatures (up to 1050 °C) and pressures (up to 5000 bar) in the lab, and we used a wide variety of geochemical methods to provide comprehensive constraints on the depth and temperature of the magma chamber beneath Lascar volcano.
