Identify Your Rock: Key Mineral Traits (With Photos)

Igneous rocks can have sparkly minerals like quartz. If your rock has layered or banded patterns, it might be metamorphic. Sedimentary rocks, meanwhile, can have layers that look like pages in a book. Knowing the rock type helps because some minerals are mostly found in one type. For example, olivine is common in igneous rocks.
