Cinder cone. A cinder cone (or scoria cone[1]) is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. [2][3] The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.
Lava Butte, a cinder cone in Newberry National Volcanic Monument, Oregon. A list of cinder cones is shown below. This list is incomplete ; you can help by adding missing items .
A spatter cone is a low, steep-sided hill or mound that consists of welded lava fragments, called spatter, which has formed around a lava fountain issuing from a central vent. Typically, spatter cones are about 3–5 meters (9.8–16.4 ft) high. In case of a linear fissure, lava fountaining will create broad embankments of spatter, called ...
Strombolian eruptions consist of ejection of incandescent cinders, lapilli, and volcanic bombs, to altitudes of tens to a few hundreds of metres. The eruptions are small to medium in volume, with sporadic violence. This type of eruption is named for the Italian volcano Stromboli. The tephra typically glows red when leaving the vent, but its ...
Scoria. Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob and cooled in the air to form discrete grains called clasts. [1][2] It is typically dark in color (brown, black or purplish-red), and basaltic or andesitic in composition. Scoria has relatively low density, as it is ...
The area has many rhyolitic domes, such as Melvin Butte, plus andesitic cinder cones, including those of the Triangle Hill and Triangle Peak area, whose composition is similar to the Tumalo Tuff (and Bend Pumice), and Shevlin Park Tuff. [2] This area has andesitic and mafic cinder cones, such as Lava Butte. [3] and rhyolite domes. [4]
Schonchin Butte is a cinder cone on the northern flank of Medicine Lake Volcano in the Cascade Range in northern California. Frothy lava, cooled in the air, created the large cinder cones throughout Lava Beds National Monument. It is named for Old Schonchin, a chief of the Modoc people during the late nineteenth century.
Cinder Cone, a volcanic cone composed of ash, lapilli and scattered ropy and breadcrusted bomb fragments, was constructed during two periods of eruptive activity. [19] [21] The first eruptive period produced a tuff ring and a 9 km (5.6 mi) long basaltic andesite lava flow about 100,000 years ago following a period of glacial retreat.
