Reliable deep-time environmental and climate reconstructions are needed to understand the drivers of Earthâs system evolution over geological time. Palaeozoic temperature estimates, including reconstructions of the climate change through the Ordovic

The German Research Centre for Geosciences (GFZ) in Potsdam hosts a CAMECA 1280-HR large geometry secondary ion mass spectrometer (SIMS) with a web-based user node at the University of the Witwatersrand, South Africa. A major theme of our facility is

Knowledge of oxygen diffusion in garnet is crucial for a correct interpretation of oxygen isotopic signatures in natural samples. Scicchitano et al. (2022) reported a series of experiments with pyrope and YAG at P-T of 1-atm to 2.5 GPa and 900 °C

The study of serpentinites and ophicarbonates from ophiolitic terrains provides a three-dimensional perspective on the hydration and carbonation processes affecting modern oceanic lithosphere. The Chenaillet ophiolite (western Alps) is interpreted as

Lode gold deposits, which are currently the world’s major gold supply, have been shown to be generated mostly by phase separation of metamorphic fluids and/or interaction between these fluids and wall rocks. Here we use garnet oxygen isotopes by se

A strongly dichroic (vivid blue to near-colourless) tourmaline specimen from the Elahera gem field, central Sri Lanka, was identified as dravite. The sample shows strong Fe2+-related optical absorption (E⊥c) in the red range and comparably weak red

The capacity of garnet to preserve successive growth stages over the P–T evolution of the host rock remains unsurpassed. The distributions of major elements, trace elements and oxygen isotopes, can be mapped at high spatial resolution to decode thi

Subduction zones provide a key link between the surficial biogenic, atmospheric and hydrospheric geochemical cycles with the Earth’s internal reservoirs. Sediment compaction and dehydration of variably altered oceanic lithosphere during subduction

The ability to constrain the petrogenesis of multiple serpentine generations recorded at the microscale is crucial for estimating the extent and conditions of modern versus fossil serpentinisation in ophiolites. To address matrix bias effects during
