Is paricutin a composite shield or cinder cone volcano?

Is paricutin a composite shield or cinder cone volcano?

Geologists from many parts of the world studied Parícutin during its lifetime and learned a great deal about volcanism, its products, and the modification of a volcanic landform by erosion. Parícutin Volcano, Mexico, is a cinder cone rising approximately 1,200 feet above the surrounding plain.

Is paricutin a shield volcano?

LOCATION. Paricutin is located about 200 miles west of Mexico City. It is the youngest of 1,400 volcanic vents in the Michoacan-Guanajuato volcanic field, a basalt plateau dominated by scoria cones, but also containing small shield volcanoes, maars, tuff rings, and lava domes.

What type of cone is paricutin?

cinder cone volcano
A nine-year eruption (1943–52) of ash and lava from an open field in Michoacán state, Mexico, buries the nearby Tarascan Indian village of Paricutín and creates a new cinder cone volcano.

What is the composition of paricutin?

Most (~80%) of the Parícutin magma is basaltic andesite with 2–3% phenocrystic olivine and microphenocrysts (and microlites) of plagioclase, olivine, orthopyroxene and clinopyroxene (Wilcox, 1954). Early (February 22, 1943) and late (1950, 1952) lavas also contain minor phenocrystic plagioclase.

Why are composite shield and cinder cone volcanoes different?

Composite volcanoes are tall, steep cones that produce explosive eruptions. Shield volcanoes form very large, gently sloped mounds from effusive eruptions. Cinder cones are the smallest volcanoes and result from accumulation of many small fragments of ejected material.

Where are composite cone volcanoes found?

Famous examples of composite cones are Mayon Volcano, Philippines, Mount Fuji in Japan, and Mount Rainier, Washington, U.S.A. Some composite volcanoes attain two to three thousand meters in height above their bases. Most composite volcanoes occur in chains and are separated by several tens of kilometers.

What type of cone is our Mayon volcano?

stratovolcano
Geology. Mayon is a classic stratovolcano with a small central summit crater. The cone is considered the world’s most perfectly formed volcano for its symmetry.

How did Paricutin erupt?

In 1943, thick, sticky lava, driven by large volumes of gas, exploded from Paricutin’s vents: material that was blasted into the air to cool and solidify. Much of it fell back around the vent, forming a cone-shaped mountain of cinders. Paricutin erupted from a place where no volcano had been before.

Why is Paricutin a cinder cone volcano?

What type of cone is our Mayon Volcano?

Do cinder cones consist largely of Pyroclastics?

Cinder cones are composed of generally felsic pyroclastic material and scoria. Cinder cones are composed of generally felsic pyroclastic material and pumice.

What’s the difference between shield volcanoes and composite?

Composite cone volcanoes are cone-shaped volcanoes composed of layers of lava, ash and rock debris. Composite cone volcanoes can grow to heights of 8,000 feet or more and have explosive eruptions. Shield volcanoes are broad, domed-shaped volcanoes with long, gently sloped sides.
