Short summary
Short summary
We measured water distributions in deformed quartz by infrared spectroscopy mapping and used the results to discuss changes in water distribution resulting from textural development. Because of the grain size reduction process (dynamic recrystallization), water contents decrease from 40–1750 wt ppm in host grains of ~2 mm to 100–510 wt ppm in recrystallized regions composed of fine grains of ~10 µm. Our results indicate that water is released and homogenized by dynamic recrystallization.

Short summary
Sediments accumulated in accretionary prisms are deformed by the compression imposed by plate subduction. Here we show that deformation of the sediments transforms some minerals in them. We suggest that these mineral transformations are due to the proliferation of microorganisms boosted by deformation. Deformation-enhanced microbial proliferation may change our view of sedimentary and tectonic processes in subduction zones.

Short summary
Our rock deformation experiments (solid-medium Griggs-type apparatus) on wet assemblages of mafic compositions show that the ability of minerals to react controls the portions of rocks that deform and that minor chemical and mineralogical variations can considerably modify the strength of deformed assemblages. Our study suggests that the rheology of mafic rocks, which constitute a large part of the oceanic crust, cannot be summarized as being rheologically controlled by monophase materials.

Short summary
The Caledonian mountains formed when Baltica and Laurentia collided around 450–400 million years ago. This work describes the history of the rocks and the dynamics of that continental collision through space and time using field mapping, estimated pressures and temperatures, and age dating on rocks from northern Norway. The rocks preserve continental collision between 440–430 million years ago, and an unusual pressure–temperature evolution suggests unusual tectonic activity prior to collision.

Short summary
Using rock deformation experiments we study how rocks deform at mid-crustal levels within mountain belts and along plate boundaries. For the studied material, fluid-assisted mass transport and grain sliding are the dominant deformation mechanisms when small amounts of water are present. Our results provide new data on the mechanical response of the earth's crust, and the wide range of presented microstructures will help to correlate observations from experiments and nature.

Short summary
We investigate the extensional fault geometry and its evolution during the stretching and thinning of continental crust and lithosphere leading to continental breakup. We focus on the fault-controlled processes that thin and rupture the final 10 km of continental crust at magma-poor margins prior to mantle exhumation. We show that isostatic fault rotation in response to extension is fundamental to understanding the formation of tectonic structures observed on seismic reflection data.

Short summary
The Northeast Rift of Mt Etna is affected by ground deformation linked to gravity sliding of the volcano flank and dike injection. Drone surveys show that the rift is affected by NE-striking extensional fractures and normal faults. Given an age of 1614 CE for the offset lavas, we obtained an extension rate of 1.9 cm yr−1 for the last 406 years. The stress field is characterised by a NW–SE σHmin. Drone surveys allow us to quickly collect data with a resolution of 2–3 cm.

Short summary
Grain size is a key factor for deformation. Quartz is one of the main constituents of the crust, but little is known about grain growth that can change grain size. We therefore experimentally determined grain growth laws for quartz. We discuss the importance of the grain size exponent, water fugacity exponent, and activation energy. Our results indicate that the contribution of grain growth to deformation may become important in lower-crustal conditions.
