The trace elemental and isotopic signatures in apatite can be modified during hydrothermal
alteration. This study investigates the suitability of apatite as an indicator of the source …

The abundance and composition of volatiles in subvolcanic melts play a key role in
controlling eruptive styles of volcanoes, but they are difficult to determine directly due to …
