Water, laden with these minerals, seeps through the limestone and stains the white limestone in different colors, depending on what minerals are present at the time. Pro Tip: To get a better look at the crystals in your rocks and help with identification I highly recommend picking up a good geologist's hand lens.

Some rocks contain only one kind of mineral. Limestone (rock), for example, is often pure calcite (mineral). Anorthosite (rock) is made mostly or entirely of plagioclase (mineral). Quartzite (rock) may be made only of quartz (mineral). Dunite (Figure 1.29), an igneous rock that crystallizes from magma, is often nearly olivine (mineral).
