Evidence for the formation of silicic lava by pyroclast sintering (2024)
Journal Article
Foster, A., Wadsworth, F. B., Tuffen, H., Unwin, H. E., & Humphreys, M. C. S. (2024). Evidence for the formation of silicic lava by pyroclast sintering. Nature Communications, 15(1), 5347. https://doi.org/10.1038/s41467-024-49601-6

Silicic lavas can be produced by the sintering of pyroclasts in the volcanic sub-surface, and then advected out of the vent. Here, we provide evidence for this mechanism preserved in the exposed post-glacial remnants of a silicic volcanic conduit at...
