A group of scoria cones with recent lava flows of the Tskhouk-Karckar volcanic group are in the center of this October 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 16 km across). The longest flow to the south traveled around 9 km from the vent. The lavas have abundant lobate flow edges and pressure ridges, and overlap older cones and flows.

Sintesi geologica

The Tskhouk-Karckar volcano group of cones and lava flows is located in the NW and central part of the Syunik Volcanic Upland along the Armenia/Azerbaijan border about 60 km SE of Lake Sevan. It was constructed within offset segments of the major Pambak-Sevan-Syunik strike-slip fault trending SE from Lake Sevan. Eight pyroclastic cones produced three generations of Holocene lava flows (Karakhanian et al., 2002). Abundant petroglyphs, burial kurgans, and masonry walls were found on flows of the older two age groups, but not on the youngest. Lava flows from these cinder cones overlie petroglyphs dated to the end of the 4th millennium and beginning of the 3rd millennium BCE and are themselves used in gravesites dated to 2770 BCE +/- 140 years. Following these eruptions, the area was not repopulated until the Middle Ages.

Riassunto in inglese

Tskhouk-Karckar or Qarqar is a group of pyroclastic cones which is located in the central part of the Siunik volcanic ridge at the border of Armenia and Azerbaijan 60 km (37 mi) SE of Lake Sevan. The volcanoes lie on the northwest side of Tskhouk volcano and are constructed on a volcanic basement or rhyolites, basaltic andesites and dacites. The volcanoes erupted voluminous and long lava flows, grouped in three age-based stages of varying age and conservation. Petroglyphs have been found buried under the most recent stages and broken by earthquake activity, suggesting activity between the 4th–early 3rd millennium BC and 4720 ± 140 years BP, a date established by C14 analysis on graves inside the lava flows. There is evidence indicating that the last stage of activity resulted in abandonment of the area by humans, only resuming during the Middle Ages.
