The central part of the 40-km-long (N-S) Samsari Volcanic Center is shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 30 km across). At least 20 edifices form the complex, and the Samsari edifice and caldera is in the center of the top third of this image. The southernmost cone in this image is Patara Abuli and the closest NW cone is Didi Abuli.

지질학적 요약

The Samsari Volcanic Center consists of more than 20 volcanoes extedning about 40 km N-S along the Samsari Ridge, part of the Dzhakheti Highland of southern Georgis, 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.

Mount Samsari is a peak of the Abul-Samsari Range in Southern Georgia. The elevation of the mountain is 3,285 metres (10,778 ft) above sea level. Mount Samsari represents a volcanic cone, inside of which lies a caldera with a diameter of 3 kilometres (1.9 mi) with a semicircular ridge surrounding it. The formation of the caldera is linked to local fault systems. The floor of the caldera is lined with rocks and glacial debris as well as small lakes and contains volcanokarst formations. The caldera rim contains traces of previous glaciation, including cirques. The mountain was built up during the late Quaternary period and is made up of andesites, dacites and rhyolites. The slopes of Samsari are mainly devoid of vegetation. The caldera formed roughly 200ka ago.
