Lava rocks are rocks that occur as a result of a volcano, so they are volcanic rocks. These rocks generally serve many purposes and can be harvested or mined from volcanic regions worldwide. Here, we look at how they are harvested, where they can be found, and the use of these lava rocks.
In the United States, Lava rocks are harvested from places such as Hawaii, Utah, California, Colorado, New Mexico, etc. These rocks are ancient, and some result from a volcanic eruption that happened 20,000 years ago or even later than that. Although referred to as lava rocks, they are not technically lava. What is referred to as lava is the molten rock that comes out of an active volcano? Once it is exposed to the atmosphere, it cools off and hardens to become an igneous rock.
The areas where the lava rocks form are usually called the scoria cone or cinder cone. It is easy to harvest the stones from this area. This is so because the rock is porous. All you have to do is push it off the hill. Since the stones come in various sizes, miners and quarries usually sort out the rocks into different sizes. Perhaps the difficult part is finding the right amount of these rocks to mine. Generally, finding a volcanic area with stones that can still be harvested means the rocks are relatively
