Transition from dome-forming to plinian eruptive styles controlled by H2O and Cl degassing

Nature volume 392, pages 65–69 (1998)Cite this article

Abstract

The transition from a plinian (pumice) to an effusive (dome-forming) eruptive style is frequently observed in volcanic systems and is generally attributed to the progressive loss of volatiles from magma stored in a superficial reservoir. This explosive–effusive transition has been explained by the evolution from a closed to an open system of degassing1,2,3,4. But in this context, an eruption at Mt Pelée (Martinique, French West Indies) dated at 650 years ago, which exhibited a rarely observed5,6 succession from dome-forming to plinian activity in a short interval of time7, is at odds with such an explanation. In this eruption, near-surface explosions of the dome produced two peléean turbulent pyroclastic flows, whose deposits are similar to those of the effusive 1902 eruption, and then plinian activity produced pumice fallouts and flows. The reconstruction of the degassing paths of both eruptive regimes using the densities and the H2O and Cl contents of the clasts shows that the interaction of rising magma with hydrothermal fluids at shallow depth may play a critical role in determining eruptive style.
