Cinder cones are generally small volcanoes produced by brief eruptions with a total vertical relief of less than a few thousand feet. If the molten rock solidifies before the gas has escaped, the bubbles become small rounded or elongated cavities in the rock. It is the only rock type that does this scoria and vesicular basalt will both sink like other rocks. Scoria-producing volcanoes usually have short eruptions and are not very long. The compositions of peridotite nodules found in certain basalts and diamond pipes (kimberlites) are of special interest, because they provide samples of Earths mantle brought up from depths ranging from about 30 km to 200 km or more. The difference is probably the result of lower magma viscosity, allowing rapid volatile diffusion, bubble growth, coalescence, and bursting.
