Quartz is one of the most common of all minerals that make up the continental crust. It is found in igneous, metamorphic, and sedimentary rocks. It is associated with many valuable ore deposits as well. Amethyst is a variety of quartz and owes its purple color to the presence of iron. It is composed of silicone dioxide SiO 2.: Rose Quartz is a variety of quartz and owes its pink color to the
A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids. Some rocks are predominantly composed of just one mineral. For example, limestone is a sedimentary rock composed almost entirely of the mineral calcite. Other rocks contain many minerals, and the specific minerals in a rock can vary

Hi, my name is Larry and I want to tell you everything I know about rocks and minerals. Rocks are made up of different types of minerals — a bit like the ingredients in a cake! There are three main groups of rocks — these are sedimentary, igneous and metamorphic. You can see how each of them is formed in the rock cycle diagram:

Introduction to Rocks & Minerals. Share Minerals are naturallyoccurring, solid substances composed of chemical elements. This means that minerals, ranging from salt to rubies, are made up from the elements that appear on a periodic table. They are inorganic, not living or made up of living things.
Minerals and rocks Edit. Minerals are different from rocks. A mineral is a chemical compound with a given composition and a defined crystal structure. A rock is a mixture of one or several minerals, in varying proportions. A rock has only two of the characteristics minerals have–it is a solid and it
Geology is the study of the nonliving things that the Earth is made of. Geology is the study of rocks in the Earth's crust. People who study geology are called geologists.
