Orbicular granite

Orbicular granite is a type of rock that is different from regular granite because it has round spots in it that kind of look like polka dots. It's made up of different minerals like feldspar, quartz, and mica that formed over a really long time, like millions of years, under the earth's surface.

The spots in orbicular granite are created by a process called "orbiculation", which is a fancy word that means the minerals in the rock were pushed together and then cooled down really slowly. This makes them form little circles or orbs.

So, orbicular granite is like a special kind of granite with round spots in it that were made by all the different minerals coming together in a cool way. It's not very common to find and some people really like it because it looks unique and different from other types of rocks.
