Mount St. Augustine is a stratovolcano and lava domes
There are two volcanoes in Afghanistan. Dacht-i-Navar is a volcano group with 15 lava domes, located southwest of Kabul. The Vakak Group is located WSW of Kabul, and consists of 18 domes.
bulbous masses are associated with lava domes
Acid Lava Dome is a type of volcano that forms when viscous acid lava solidifies quickly to form a volcano with steep convex sides.
When the lava ejected is too thick to flow, it solidifies near the vent and can form a dome-shaped feature called a lava dome. Lava domes are typically made of highly viscous lava, which does not flow easily. They can grow slowly over time as more lava is added to the dome from the eruption.
Lava domes in Arizona are primarily found in the San Francisco Volcanic Field, located near Flagstaff. The region features several notable lava domes, such as Sunset Crater and the surrounding formations. These domes were created by the slow extrusion of viscous lava, resulting in steep, mound-like structures. The area is significant for studying volcanic activity and geology in the southwestern United States.

A lava domes is a structure that forms when a volcano extrudes very viscous lava that builds into a dome-shaped pile rather than flow downhill.
Lava domes usually consist of rhyolite or dacite lava.
There are two volcanoes in Afghanistan. Dacht-i-Navar is a volcano group with 15 lava domes, located southwest of Kabul. The Vakak Group is located WSW of Kabul, and consists of 18 domes.
Lava domes are generally composed of felsic, highly viscous lava, usually dacite or rhyolite.
Not exactly. Some volcanoes do consist of simply a lava dome, but most lava domes are found in or on stratovolcanoes.
