Formation of Minerals: Where Do Minerals Come From?
As it flows through open spaces in rocks, it deposits solid minerals. The mineral deposits that form when a mineral fills cracks in rocks are called veins. Figure 3.24 shows white quartz veins. When the minerals are deposited in open spaces, large crystals can form. These special rocks are called geodes.
