- Abstract:
- The competing models for the origin of large high-silica, caldera forming eruptions are (i) from long-lived, zoned magma chambers, (ii) re-melting of plutons, and (iii) shallow-level interactions between different magmas. These models can now be tested because of the different predicted relationships between the different magma types involved, and because they imply different time scales in the range 100 to 100,000 years which can be determined from U-Th-Pa-Ra isotopes. The1912 Katmai-Novarupta eruption has been the subject of detailed stratigraphic analysis, and this project is to determine the pre-eruption ages of both the different magmas and selected phenocrysts, together with other geochemical data, from separate andesite, dacite and rhyolite clasts that occur through most of the zoned sequence.
