2. Volcanic rock - Wikipedia

   en.wikipedia.org/wiki/Volcanic_rock

   The terms lava stone and lava rock are more used by marketers than geologists, who would likely say "volcanic rock" (because lava is a molten liquid and rock is solid). "Lava stone" may describe anything from a friable silicic pumice to solid mafic flow basalt, and is sometimes used to describe rocks that were never lava, but look as if they ...

   Rivers of lava spewed from a fissure in the mountainside, snaking downwards and erupting in fountains of red and gold molten rock when the Fagradalsfjall volcano erupted this week in a fishing ...

4. Lava - Wikipedia

   en.wikipedia.org/wiki/Lava

   Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F). The volcanic rock resulting from subsequent cooling is also often called lava. A lava flow is an outpouring of lava during an effusive eruption.

5. Scoria - Wikipedia

   en.wikipedia.org/wiki/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.

6. Carrizozo volcanic field - Wikipedia

   en.wikipedia.org/wiki/Carrizozo_volcanic_field

   The volcanic field consists of two lava flows, the Broken Back flow and the Carrizozo lava flow (Carrizozo Malpais), the second youngest in New Mexico. [5] Both lava flows originated from groups of cinder cones. The Broken Back flow is approximately 16 kilometres (10 mi) long and the Carrizozo, one of the largest in the world, is 68 kilometres ...

7. Cima volcanic field - Wikipedia

   en.wikipedia.org/wiki/Cima_volcanic_field

   This flow may have been preceded by a previous lava flow which was later buried by the main flow. [36] An older vent lies just south-southwest of the Black Tank Cone. [37] The field presents black and red volcanic rocks [11] in the form of cinders, exposed feeder dikes and lava bombs, as well as agglutinates which are exposed in gullies and ...
