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.
Cinder cone Parícutin is a large cinder cone in Mexico. Cinder cones, also known as scoria cones and less commonly scoria mounds, are small, steep-sided volcanic cones built of loose pyroclastic fragments, such as either volcanic clinkers, cinders, volcanic ash, or scoria.

454 million-year-old volcanic ash between layers of limestone in the catacombs of Peter the Great's Naval Fortress in Estonia near Laagri. This is a remnant of one of the oldest large eruptions preserved. The diameter of the black camera lens cover is 58 mm (2.3 in). Volcanic ash is formed during explosive volcanic eruptions and phreatomagmatic ...
Cinder Cone is a cinder cone volcano in Lassen Volcanic National Park within the United States. It is located about 10 mi (16 km) northeast of Lassen Peak and provides an excellent view of Brokeoff Mountain, Lassen Peak, and Chaos Crags. The cone was built to a height of 750 ft (230 m) above the surrounding area and spread ash over 30 sq mi (78 ...
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.
Basalt that erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder ; [62] and lava flows. [63] Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated, imparting a lightweight "frothy" texture to the rock. [64]
