Strombolian eruptions during the second and final eruptive period about 10, 000 years ago constructed a small pyroclastic cone on the eastern rim of the older basaltic andesite tuff ring.
32.
Numerous pyroclastic cones dot the lower flanks of basaltic to basaltic andesite volcano, particularly on the NW and SE sides, including an offshore cone formed during the 1933 34 eruption.
33.
The eastern end of the island is capped by a thin veneer of basaltic volcanic rocks, erupted from several pyroclastic cones including Pumpkin Hill which forms the highest point on the island.
34.
A unit of basalt pyroclastic cones and lava flows in the northwest of the field has been dated 100, 000?0, 000 to 170, 000?0, 000 years ago from two samples.
35.
The range is Pliocene in age and on its southwestern flank contains Pleistocene subglacial and subaerial cones and its northwest and southwest sides contain Holocene pyroclastic cones and volcanic complex could be The Ash Pit.
36.
The youngest volcanism, at Vulc�o do Pared�o ( ) on the southeast tip of the island, constructed a pyroclastic cone with lava flows that are no older than the Holocene ( Almeida, 1961 ).
37.
Volcanes de Caburgua is a group formed by six pyroclastic cones located at the southern tip of the Caburgua Lake, which is a lava-dammed lake created by volcanic activity from the just mentioned cones.
38.
The volcanism that originated Facho was submarine in nature, with two visible centres positioned in the southern part of the island : Pico do Facho and a second pyroclastic cone situated west of Rocha Alta ( the remains of its chamber still visible along the coast ).

"' 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 ( Nagorno-Karabakh Republic ) 60 km SE of Lake Sevan.
