 Minerals - a mineral is a solid inorganic substance of natural occurrence.

**Characteristics of a Mineral - **  **The streak of a mineral refers to the color left on a streak plate after rubbing a mineral across its surface. A streak plate can be as simple as the unglazed side of a porcelain tile.

It's not just a "mix" of stuff. A native mineral is a mineral that is found in a specified place. If we consider quartz, the most abundant mineral on earth, it could be said to be native to just about anywhere. 
 * Chemical Properties of a Mineral**

Mineral Families**  The Mica and The Feldspar The silicates are a combination of silicon, oxygen, and another element. Depending on the element, the resulting mineral's density and color can vary considerably. ** Classifying minerals can range from simple to very difficult. A mineral can be identified by several physical properties, some of them being sufficient for full identification without equivocation **.
