Volcanic Activity
Eruptions of Nemrut were mainly of Plinian type. Their products are mainly alkaline and include a wide range of lavas: from basalt to rhyolite and phonolite, as well as pyroclastic emissions and slag. Eruption of different periods were either effused or explosive. Nemrut is located on a fault that crosses the volcano from the north to the south and contains the main crater and a number of small craters, maars, hot springs and fumaroles.

The volcanic activity of Nemrut occurred in three stages: the formation of a cone (pre-caldera stage), the post-caldera stage, and the late stage. Further, divisions are debatable and are based on different interpretations of the stratigraphic data.
