[2014] akabilly1 (Earth Science-Colfax): Scoria

Scoria

Scoria can be used for high-temperature insulation. Scoria is used on oil well sites to limit mud issues with heavy truck traffic. It is also used as a traction aid on ice and snow covered roads

Scoria is a highly vesicular, dark colored volcanic rock. It is typically dark in color, and basaltic or andesitic in composition. Scoria is relatively low in mass , but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. As rising magma encounters lower pressures, dissolved gases are able to exsolve and form vesicles. Scoria forms when magma containing abundant dissolved gas flows from a volcano or is blown out during an eruption. As the molten rock emerges from the Earth the pressure upon it is reduced and the dissolved gas starts to escape in the form of bubbles.

Well...some can.

America Loves Scoria

You can skii on it!
