Is Lava Butte a cinder cone volcano?
Lava Butte is a cinder cone rising 500 feet above Lava Lands Visitor Center. A cinder covered trail encircles the rim of the cone with outstanding views.
What type of volcano is Lava Butte?
cinder cone
Lava Butte is a cinder cone that formed about 6,000 years ago. It formed as gas-rich basaltic magma erupted explosively. The bits of magma cooled quickly in the air, forming frothy scoria.
What is a volcanic butte?
In geomorphology, a butte (/bjuːt/) is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands.
When did Lava Butte erupt?
The Lava Butte shield volcano, also known as Rocky Butte, lies south of Jordan Craters, and is 0.03-0.09 million years old (Hart and Mertzman, 1983). The slightly older Clarks Butte shield lies to the north and has been dated at 0.25 million years.
How was Lava Butte formed?
Lava Butte formed 7,000 years ago when highly gas-charged magmas erupted along a zone of weakness (the Northwest Rift Zone). Cinders and ash were thrown high into the air as the first magma reached the surface, much like opening a bottle of soda pop after shaking it.
Where is Lava Butte?
central Oregon
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, Oregon, and Sunriver, Oregon in Deschutes County. It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast.
Where is Lava Butte located?
Oregon
Explore this 3.8-mile out-and-back trail near Sunriver, Oregon. Generally considered a moderately challenging route, it takes an average of 1 h 42 min to complete.
How are cinder cone volcanoes formed?
Cinder conesCinder cones, sometimes called scoria cones or pyroclastic cones, are the most common types of volcanic cones. They form after violent eruptions blow lava fragments into the air, which then solidify and fall as cinders around the volcanic vent.
How does a cinder cone volcano erupt?
Cinder cones are the simplest type of volcano. They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone.
What type of lava erupts from a cinder cone volcano?
basaltic lava flows
Most cinder cones have a vent at the base or side of the volcano where basaltic lava flows are erupted.
What kind of lava do cinder cone volcanoes have?
Most cinder cones have a vent at the base or side of the volcano where basaltic lava flows are erupted.
Where do cinder cone volcanoes usually form?
Cinder cones are commonly found on the flanks of shield volcanoes, stratovolcanoes, and calderas. For example, geologists have identified nearly 100 cinder cones on the flanks of Mauna Kea, a shield volcano located on the Island of Hawai`i (these cones are also referred to as scoria cones and cinder and spatter cones).
What type of magma is in a cinder cone volcano?
Chemical Composition Most cinder cones form through eruption of lava of basaltic composition, although some form from lava. Basaltic magmas crystallize to form dark rocks containing minerals that are high in iron, magnesium and calcuim but low in potassium and sodium.
How is a cinder volcano formed?
They form after violent eruptions blow lava fragments into the air, which then solidify and fall as cinders around the volcanic vent. Usually the size of gravel, these cinders are filled with many tiny bubbles trapped in the lava as it solidifies. Cinder cones stand at heights of tens of meters to hundreds of meters.
What happens when a cinder cone volcano erupts?
Cinder cones form from ash and magma cinders–partly-burned, solid pieces of magma, that fall to the ground following a volcanic eruption. This type of eruption contains little lava, as the magma hardens and breaks into pieces during the explosion.
