Short summary
Inclusions in natural rocks are an invaluable asset for geoscientists because they provide information about processes in the Earth's history that are otherwise hidden or subsequently overprinted. In this paper we review the development over the last 200 years of the concepts and methods to measure the remnant pressures in mineral inclusions and how they can be used to determine pressures and temperatures at which the inclusions were formed deep within the Earth.

We studied primary granitic and halogen-rich melt inclusions trapped in mantle rocks in the Bohemian Massif (Germany) in order to retrieve important information about the nature of the melt and the source rock. The melt was produced by the partial melting of metasediments during the deepest stages of subduction and interacted with the mantle. This work is an excellent example of transfer of crustal material, volatiles in particular, in the mantle during the subduction of the continental crust.

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.

We examined the influence of Al2O3 and H2O on the position of the coesite–stishovite transition by means of in situ X‑ray diffraction measurements with the large-volume press at the synchrotron PETRA III in Hamburg. The position of the transition was found to be shifted almost in parallel by about 1.5 GPa to lower pressures compared to results for the pure SiO2 system by Ono et al. (2017). Stishovite of this study containing Al and H is only partially quenchable but transforms back to coesite.

The equilibrium phase of A + HP clinoenstatite = forsterite + water was experimentally investigated at aH2O = 1 in situ. In cold subducting slabs, it is of relevance to transport water to large depths, initiating the formation of dense hydrous magnesium silicate (DHMS). At normal gradients, the huge water amount from this reaction induces important processes within the overlying mantle wedge. We additionally discuss the relevance of this reaction for intermediate-depth earthquake formation.

Short summary
Dense hydrous magnesium silicates, like the 3.65 Å phase, are thought to cause deep earthquakes. We investigated the dehydration of the 3.65 Å phase at P and T. In both directions of the investigated simple reaction, additional metastable water-rich phases occur. The observed extreme reduction in grain size in the dehydration experiments might cause mechanical instabilities in the Earth’s mantle and, finally, induce earthquakes.

Short summary
Garnet often entraps small droplets of deep melts generated during mountain building processes. Using high-resolution techniques, we studied these droplets in order to provide hard numbers for the quantification of volatile budgets during crustal evolution, show how even melts formed at >1000°C contain water, and clarify how water behaves during metamorphism and melting at the microscale. Moreover, we provide the very first data on chlorine in natural melts from crustal reworking.
