What Is Volcanic Rock Made Of. Plate tectonic activity in the earth's crust forms deposits of molten rock (or magma). This magma contains trapped, pressurized gases. By contrast, molten material that has erupted onto. When this mushy melt is found underground penetrating other rocks, it's called magma, and the solidified rock is termed intrusive. Examples include basalt, rhyolite, and andesite. Volcanic rocks are divided into three main types: Properties and characteristics of igneous rocks. These rocks are crucial in deciphering the earth’s geological history and the processes occurring beneath its surface. Most extrusive (volcanic) rocks have small crystals. Volcanoes are like a spewing bottle of soda. Volcanic rock types are igneous rocks formed through the solidification of molten magma ejected during volcanic eruptions. Over time, after several eruptions, the rock builds up and a volcano forms. Obsidian is an example of an extrusive igneous rock that is amorphous or lacks crystalline structure. If the confining pressure of the magma decreases or gas pressure within increases, the contents simply blast through to the surface.
