サムサリ山

The Samsari Volcanic Center consists of more than 20 volcanoes extending about 40 km N-S along the Samsari Ridge, part of the Dzhakheti Highland of southern Georgia, about 90 km WSW of Tbilisi. The most prominent volcanoes are Shavnabada in the north, the Samsari Caldera, and Didi-Abuli in the south. K-Ar dates obtained by Lebedev et al. (2003) showed that the oldest rocks were about 400 ka, from Didi-Abuli; the Samsari caldera was active around 200 ka. One sample from Tavkvetili volcano, a feature with a well-preserved crater at the far northern edge of the range, dated to <30 ka. A lava flow from Godorebi volcano, just north of Didi-Abuli, had a similar date.
