We present Thermobar, a new open-source Python3 package for calculating pressures, temperatures, and melt compositions from mineral mineral-melt equilibrium. Thermobar allows users to perform calculations with >100 popular parametrizations involving liquid, olivine-liquid, olivine-spinel, pyroxene only, pyroxene-liquid, two pyroxene, feldspar-liquid, feldspar, amphibole amphibole-liquid, gar...

Mt. Cameroon is one of the most active volcanoes in Africa and poses a possible threat to about half a million people in the area, yet knowledge of the volcano's underlying magma supply system is sparse. To characterize Mt. Cameroon's magma plumbing system, we employed mineral-melt equilibrium thermobarometry on the products of the volcano's two most recent eruptions of 1999 and 2000. Our resul...

Quartz inclusion thermobarometry utilizes the pressureand temperature-sensitive Raman peak shifts of quartz inclusions in garnet to determine formation pressure and temperature (PT) conditions. The measured Raman shift indicates the pressure currently retained in the inclusions at ambient external conditions, such that entrapment PT conditions (i.e., P and T of garnet growth) can be determined ...

introduction volcanic rocks with a porphyritic texture have experienced two crystallization stages. the first is slow, resulting in phenocrysts, and the second, which took place at, or near the surface, or during intrusion into a cooler body of rock, result in a groundmass of glass, or fine crystals. the pressure and temperature history of a magma during crystallization is recorded in the chemi...

Abstract. Clinopyroxene-only thermobarometry is one of the most practical tools to reconstruct crystallization pressures and temperatures clinopyroxenes. Because it does not require any information coexisting silicate melt or other co-crystallized mineral phases, has been widely used elucidate physiochemical conditions crystallizing magmas. However, previously calibrated clinopyroxene-only ther...
