Short summary
Short summary
This work deals with a challenging case of a commercial clay from Gomsiqe–Puka (Albania) contaminated by mineral fibres. Detection and quantification of asbestos in this material push the boundaries of current experimental methods. Using TEM, micro-Raman spectroscopy, and EPMA, we identified the presence of asbestos tremolite, along with a rare fibrous variety of diopside. The impact of milling on the detection and quantification of mineral fibres was also evaluated.

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.
