Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite, hematite, and chert. Once considered a waste material, taconite became an important ore after higher grade deposits were depleted. Today's commercial taconites contain 25 to 30% iron by weight.

Muscovite is found in igneous, metamorphic, and sedimentary rocks. In igneous rocks, it is a primary mineral that is especially common in granitic rocks. In granite pegmatites, muscovite is often found in large crystals with a pseudohexagonal outline. These crystals are called "books" because they can be split into paper-thin sheets.

Relate some common uses of metamorphic rocks. Metamorphism. Metamorphic rocks start off as igneous, sedimentary, or other metamorphic rocks. These rocks are changed when heat or pressure alters the existing rock's physical or chemical make up. One ways rocks may change during metamorphism is by rearrangement of their mineral crystals.

What is the process of making sedimentary rocks? Sedimentary Rock Formations Sedimentary rocks are made up of 1) weathering preexisting rocks, 2) transportation of weathering products, 3) material deposition, followed by 4) compaction, and 5) sediment cementation to form a rock. Lithification is the name given to the latter two steps.

(For more on sedimentary rock, see Rocks.) On the other hand, clastic and organic particles may be buried, but before becoming lithified (turned to rock), they once again may be exposed to wind and other forces of nature, in which case they go through the entire cycle again: weathering, erosion, transport, deposition, and burial. This cycle may ...
