Part I. Weathering of rock Granite Rock (an igneous rock)

Granite Rock (an igneous rock) Rocks are composed of minerals. A mineral is a naturally occurring, inorganic, solid substance that has (1) a characteristic chemical composition; (2) an ordered internal structure that leads to (3) characteristic physical properties. As shown in Figure 1, the common rock granite is composed of several minerals.Graphite is a dark gray to black, very soft, shiny metallic mineral with a distinctive greasy feeling. One of the Earth’s softest minerals, graphite will easily leave marks on paper, which is why it is used for fine artist pencils. Even modern pencil ‘lead’ is composed of graphite mixed with clay. Paradoxically, even though graphite is ...Graphite | Common MineralsGraphite is a mineral of extremes. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity. In contrast, it is extremely resistant to heat and nearly inert in contact with almost any other material. These extreme properties give it a wide range of uses in metallurgy and manufacturing.

Magnetite | Common Minerals

Magnetite is a black, opaque, magnetic mineral that leaves a black streak when rubbed across a hard rough surface. It is one of the most abundant metal oxides, and its crystal structure contains both the ferrous (Fe+2) and ferric (Fe+3) forms of iron ions. A complex pattern of electrons between the two forms of iron is the source of its ...Solid Surface Materials - Volume Prices. Browse By Size or Color For Your Custom Projects!
