WebMay 5, 2024 · This book includes innovative gas-geothermometers and geobarometers, which are urgently needed to estimate the increasingly higher temperatures and pressures present at depth below the Solfatara volcano, owing to its on-going unrest. WebJun 1, 1997 · The first consisted of 98 specimens containing garnet and biotite from west-central Maine, which formed under reducing f O2 with graphite, a limited range of P (~3 to 4.5 kbar), and a moderate range in T (~550–650 °C), and which were all analyzed on a single microprobe using the same standards.
