Aragats is a large andesitic-to-dacitic stratovolcano in NW Armenia about 40 km NW of the capital city of Yerevan. The 4095-m-high main edifice is dissected by glaciers and is of Pliocene-to-Pleistocene age. Satellitic cones and fissures are located on all sides of the volcano and were the source of large lava flows that descended its lower flanks. Several of these were considered to be of Holocene age, but later Potassium-Argon dating indicated mid- to late-Pleistocene ages. The youngest lower-flank flows have not been precisely dated, but are constrained as occurring between the end of the late-Pleistocene and 3000 BCE (Kharakanian et al., 2003). A 13-km-long, WSW-ENE-trending line of craters and pyroclastic cones cuts across the northern crater rim and is the source of young lava flows and lahars; the latter were considered to be characteristic of Holocene summit eruptions.

The Global Volcanism Program is not aware of any Holocene eruptions from Aragats. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Aragats page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The twin northern summits of Aragats volcano in NW Armenia are seen from a ridge to the south. Extensive hydrothermal alteration has modified rocks in the summit region of this large andesitic-to-dacitic stratovolcano. The 4095-m-high main edifice of Aragats is dissected by glaciers and is of Pliocene to late-Pleistocene age. Satellitic cones and fissures have produced lava flows of late-Pleistocene to possible Holocene age.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
