Different types of rocks and minerals – Igneous rocks. There are so many features of igneous rocks. Igneous rocks are formed from the cooling and solidification of magma. Those that are very light have more acid and contain more than 60 percent silica. Those that are darker have lesser volume of ferro magnesian minerals and are more basic. Therefore, igneous
