A complex volcano, also called a compound volcano, is a mixed [[landform]] consisting of related [[volcano|volcanic centers]] and their associated [[Lava|lava flows]] and [[pyroclastic rock]]. They may form due to changes in [[Types of volcanic eruptions|eruptive habit]] or in the location of the principal vent area on a particular volcano.
es can also form a large
caldera that gets filled in by a lava dome, or else multiple small
cinder cones,
lava domes and
craters may develop on the caldera's rim.
Although a comparatively unusual type of volcano, they are widespread in the world and in geologic history.
Metamorphosed ash flow
tuffs are widespread in the
Precambrian rocks of northern
New Mexico, which indicates that caldera complexes have been important for much of Earth's history.
Yellowstone National Park is on three partly covered caldera complexes. The
Long Valley Caldera in eastern
California is also a complex volcano; the
San Juan Mountains in southwestern
Colorado are formed on a group of
Neogene-age caldera complexes, and most of the
Mesozoic and
Cenozoic rocks of
Nevada,
Idaho, and eastern California are also caldera complexes and their erupted ash flow tuffs. The
Bennett Lake Caldera in
British Columbia and the
Yukon Territory is another example of a Cenozoic (
Eocene) caldera complex.
