Volcanic crater.
Metamorphic rock, such as schist or gneiss, can be formed when volcanic rock is altered by heat and pressure. This process can cause the mineral composition and texture of the rock to change, resulting in a new type of rock with different features than the original volcanic rock.
The hollow area at the top of a volcano is known as the crater. It is a bowl-shaped depression where volcanic activity occurs, such as eruptions, gas emissions, and lava flows. Craters can vary in size and depth depending on the type of volcano.

The type of rock typical of island arcs is andesite. Andesite is an intermediate volcanic rock that is commonly found in volcanic arcs where oceanic crust subducts beneath continental crust, forming magma that eventually erupts to create volcanic islands.

The kind of rock you see forming in Puu Oo crater is extrusive igneous. This type of rock is formed by lava.

Siliceous volcanic glass is also known as obsidian.
