Silicon (Si) is a semi-metallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silicate ion SiO 44- in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals.

In sedimentary dolostones, dolomite is most often associated with calcite, aragonite, gypsum, anhydrite, chert, and halite. Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite.

2. Granite. Granite is a complex stone, which is why it comes in so many colors. It's loosely defined as a coarse-grained, quartz-rich, intrusive igneous rock. Auriferous granite often contains gold-bearing quartz veins as well, and these veins are generally sought out first by miners due to their higher gold content.
