Previous Works Thesis Project The Process

My area of study will be the Mayon Volcano in Albay Province in the Philippines. Mayon Volcano is one of the most active voclanoes in the Philippines as identified by PHIVOLCS. I will try to unravel the eruptive styles of the volcano by studying its melt inclusions.

What are melt inclusions (MI)? They are small blebs of silicate melts that are trapped within phenocrysts at particular magmatic temperatures and pressures. MI's are good trap of magma from degassing. These melt inclusions could contain the relative abundance of volatiles in the magma prior to eruption.

Photomicrographs of quartz phenocrysts showing general characteristics of silicate-melt inclusions in lavas. a) Silicate-melt inclusion with negative crystal shape (bipyramidal habitus). The inclusion consists of glass, a bubble and a small daughter mineral present beside the gas bubble; from the Mt. Doré (J.L.R. Touret, private collection). b) Silicate-melt inclusions in quartz from the Mt. Doré (J.L.R. Touret, private collection). One inclusion consists of glass and various bubbles (indicated with a black arrow). Others are bubble-free (indicated with an empty arrow). c) Fluid-rich silicate-melt inclusion, which contains three large gas bubbles. This feature may be interpreted as trapping of a fluid saturated magma; from Mt. Amiata (Italy). d) Glassy bubble-free silicate-melt inclusion; the inclusion formed during trapping of a solid inclusion; from the Mt. Doré (J.L.R. Touret, private collection).
