In general, such rocks usually have an ultrabasic protolith, like peridotite, dunite, or pyroxenite. Ferriginous. Rocks that are rich in Fe with little Mg are termed ferriginous. Such rocks could be derivatives of Fe-rich cherts or ironstones.

Rocks are made of minerals. Only a few minerals are rock forming and most rock is made from a combination of the commonest of these such as feldspars, quartz, mica, olivine, calcite, pyroxene and amphiboles. Most other minerals, of which there are over 3000 different types, are rarely present in quantities large enough to be.

If able, get your hands on some real rocks for students to touch and observe. You can purchase simple rocks and minerals kits if your school doesnt already have some. If this isnt an option, then pictures of real rocks not clip art are best As an introductory activity, before we go over how rocks are classified, I like to let students work in small groups and decide how they might sort them.

Rocks are composed of minerals. A mineral is a naturally occurring substance which is usually solid, crystalline, stable at room temperature and inorganic. There are almost 5000 known mineral species, yet the vast majority of rocks are formed from combinations of a few common minerals, referred to as rock-forming minerals.
