Short summary
The two most recent eruptive events of Nisyros volcano (Greece) record the interaction between variably evolved magmas by the presence of mafic enclaves, indicative of multiple recharge events within the magma chamber. We use the mineral chemistry composition to constrain the location of the main eruptible reservoirs and their evolution at the transition from explosive to effusive activities, with implications for magma migration and storage in the crust.

During project STARDUST, over 5500 specimens were recovered. Among them, a micrometeorite from Oslo (NMM/L2) revealed a new Al–Cu alloy with Al₄Cu₉ stoichiometry. This phase was approved as a new mineral named jonlarsenite. The microspherule shows features typical of micrometeorites. Its extraterrestrial origin is confirmed by oxygen isotope composition and chondritic chemistry, similar to previously known Al–Cu meteoritic materials.

Short summary
A new rare-earth-bearing silicate is described from a manganese ore deposit in the Pyrenees. It belongs to the epidote family and is characterised by the formula Mn2+Ce(MgAlMn2+)(Si2O7)(SiO4)F(OH). This new mineral commonly contains inclusions of an Mn-rich yttrium borosilicate, a potentially new mineral of the hellandite family. This is a new type of occurrence for hellandite – while rare earths are under the spotlight.

The As4S6 molecule was missing in the reported structures of crystalline As chalcogenides. Here we report the first occurrence of the As4S6 molecule together with the other known As4Sn (n = 3, 4, 5) molecules randomly replacing each other in the crystalline structure of a new monoclinic product obtained by the light-induced alteration of the mineral alacranite, As8S9.
