Introduction

The Ciomadul lava-dome complex is the youngest volcanic center of the Carpathian-Pannonian region. Located at the SE end of the Calimani-Harghita Range, it consists of a dacitic dome complex formed about 500-700 ka.
The dome complex is cut by twin craters, Mohos and St. Anna. The latest eruption, from St. Anna, produced subplinian airfall and pyroclastic-surge deposits that have been variously dated between about 10.7 and 42 ka. Pecskay et al. (2006) noted ages of 1.0-0.03 Ma. A number of samples from other South Harghita locations (Porcuhu, Cucu, Kapus, Pilisca, Balvanyos, Haramul Mare, and Koves Peak) had Quaternary dates.
