英文摘要The timing of Late Pleistocene volcanic activity of the Ciomadul (Csomad) dacitic lava dome complex, site of the youngest eruptions in the Carpathians, has been constrained by morphometric analysis and radiometric chronology. Pelean domes and asymmetric domes/coulees built up the volcano, including the central edifice that hosts the youngest twin craters of Mohos (Mohos) peat bog and lake St. Ana (Szent Anna). A comparative digital elevation model (DEM)-based morphometric analysis of lava domes (29 worldwide examples including 5 domes from Ciomadul) shows that it is the mean slope of the upper dome flank that correlates best with age. Although the logarithmic relationship is only moderately strong (R = 0.80), slope characteristics of the Ciomadul domes fit to those of 10-100 ka old domes. These young ages contradict the previous K/Ar dates giving as old as 1 Ma ages on a number of domes, but are supported by ongoing U-Pb and (U-Th)/He zircon dating. The latter methods constrain the whole volcanic activity to the past 250 ka and the emplacement of most lava domes within the period of 150-100 ka.
