Abstract

The newly available SRTM elevation database was used to obtain volumetric data for two segments of the Inner Carpathian Volcanic Chain: the Late Miocene-Quaternary Cǎlimani(Kelemen)-Gurghiu(Görgényi)- Harghita(Hargita) mountains (CGH); and the Late Miocene Slánské (Szalánci)-Tokaj mountains (ST) segment. Volumes (1) based on surface extent and thickness of volcanic rocks have been completed by (2) estimates for subsurface masses, and (3) erosionally removed volcanic material. Total volumes of the CGH and ST segments are 1563±204 and 650±40 km 3, and average individual edifice volumes are 104 and 47 km 3, respectively. Magma output rates in the CGH and STsegments are found to be apparently similar, 165.5 km 3/Ma±10 % on average, corresponding to small to moderate activity of subduction-zone stratovolcanoes. Average apparent migration rates of volcanic activity were also calculated. This rate tells us how much magma was produced in a 1 km-long section/1 Ma on the average, assuming that migration was roughly uniform. A similar ca. 3.0 km 3/Ma migration rate have been pointed out from both the CGH and STsegments.
