pyroclast's Usage Examples:

are less common, mainly basalt, andesite and dacite, transformed into spilite, keratophyre and pyroclastic rocks.

is emplaced at temperatures so hot that the soft glassy pyroclasts stick together at point contacts, and deform: this is known as welding.

A cinder cone is a steep conical hill of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or cinder that has been built around a volcanic.

Tephra may become lithified to a pyroclastic rock by cementation or chemical reactions as the result of the passage of hot gases (fumarolic.

Cinder cones are made of pyroclastic material.

004 75–100% pyroclasts 25–75% pyroclasts 0–25% pyroclasts.

andesite lava flows, pyroclastic rocks, volcanogenetic sandstones and argillites in north-central British Columbia, Canada, covering more than 30,000 km2.

planet or moon, where lava, pyroclastics and volcanic gases erupt through a break in the surface called a vent.

inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff.

The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent.

hot that the soft glassy pyroclasts stick together at point contacts, and deform: this is known as welding.

composed of the older materials, erupted from lava flows and Trachyte pyroclasts, the secondary phase corresponded to volcanic products that began erupting.
