👉 Lithuria is a term used in geology, specifically referring to the type of rock that forms the outermost layer of the Earth's crust. It is composed primarily of silicates and contains many minerals like quartz, feldspar, and mica, which are found in various shapes and sizes. Lithurites can vary in color from gray to bright green depending on their mineral content. Their presence or absence in a rock can indicate the type of rock it is made of.
