Abstract

The Ciomadul is the youngest volcano of the Carpathian-Pannonian region, which erupted last time at 32. ka. It produced high-K dacitic lava domes and pumiceous pyroclastic rocks. The dacite is crystal-rich and contains plagioclase, amphibole in addition to biotite, titanite, apatite, zircon and occasionally quartz, K-feldspar as well as olivine, clinopyroxene and orthopyroxene. There are two groups of amphiboles, characterized by low-Al and high-Al, respectively. They occur in the same samples and also as different zones of the same crystals. Thermobarometric calculations suggest that the low-Al amphiboles were formed from a low temperature (
