The protolith of a material is the original rock from which it formed. Deeper in the basalt flow you will find vesicular basalt, but the upper crust is very often scoria. Scoria tends to have fewer (but slightly larger) vesicles than pumice with much thicker walls between them. However, the sudden exposure of the lava to the cool air causes the lava to freeze and solidify, trapping the gas bubbles in place. What type of volcano does scoria come from?

If you dont have access to water it is usually sufficient to look at the ratio of vesicles to hard rock walls. Scoria differs from pumice, another vesicular volcanic rock, in having larger vesicles and thicker vesicle walls and hence is denser. 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.
