Types Of Rocks And Minerals | Types Of

There are so many types of rocks and minerals that grace the earth''s surface. While rocks can be classified into three major types, minerals on the other hand have more than 1000 different types and more are still being discovered each day. This article shall present the different types of rocks and minerals beginning from rocks.

Secondary Mineral

Secondary minerals. Secondary minerals are formed as byproducts of weathering at the Earth''s surface. Usually the formation of secondary minerals begins near the site where primary minerals are being attacked, perhaps even originating as coatings on the crystal surfaces (Casey et al., 1993; Nugent et al., 1998).
