Understanding Minerals: The Building Blocks

Minerals are the foundation of rocks and possess specific characteristics that allow for their identification and classification. A mineral is defined as a naturally occurring, inorganic solid with a definite chemical composition and an ordered atomic structure. This means minerals are not man-made, they are not derived from living organisms, they are solid, they have a predictable chemical formula (though some variation is possible), and their atoms are arranged in a repeating, crystalline pattern.

Key properties used to identify minerals include:

• Color: While useful, color can be misleading as impurities can alter a mineral’s appearance. For example, quartz can be clear, white, pink (rose quartz), purple (amethyst), or smoky.
• Streak: The color of a mineral’s powder when rubbed against an unglazed porcelain plate. This is often more consistent than the mineral’s surface color. For example, hematite always produces a reddish-brown streak, regardless of its surface appearance.
• Luster: How light reflects off the mineral’s surface. Common terms include metallic, glassy (vitreous), dull (earthy), and waxy.
• Hardness: A mineral’s resistance to scratching, measured using the Mohs Hardness Scale (ranging from 1 for talc to 10 for diamond). For instance, calcite has a hardness of 3, while corundum has a hardness of 9.
• Cleavage and Fracture: Cleavage refers to a mineral’s tendency to break along smooth, flat surfaces, determined by its atomic structure. Fracture describes how a mineral breaks when it doesn’t have cleavage, often resulting in irregular or curved surfaces. Mica exhibits perfect cleavage, easily splitting into thin sheets, while quartz, lacking cleavage, fractures conchoidally (like broken glass).
• Specific Gravity: The ratio of a mineral’s density to the density of water, indicating how heavy it feels for its size.

Common minerals discussed in earth science modules include quartz, feldspar, mica, calcite, and olivine. These are often the primary components of the rocks found across Wisconsin, including near Madison.

Formation of Minerals

Minerals form through various geological processes. Crystallization from molten magma or lava (igneous processes), precipitation from water (sedimentary or hydrothermal processes), and recrystallization due to heat and pressure (metamorphic processes) are the primary ways minerals are created. The conditions under which a mineral forms—temperature, pressure, and chemical environment—dictate its final properties.

Understanding Rocks: Aggregates of Minerals

Rocks are aggregates of one or more minerals, or sometimes mineraloids. They are classified into three main categories based on how they are formed:

• Igneous Rocks: Formed from the cooling and solidification of molten rock (magma below the surface, lava above the surface). Examples include granite (formed from slow cooling magma, with visible crystals) and basalt (formed from faster cooling lava, often fine-grained). The texture of igneous rocks (e.g., coarse-grained, fine-grained, glassy) provides clues about their cooling rate.
• Sedimentary Rocks: Formed from the accumulation, compaction, and cementation of sediments (fragments of other rocks, minerals, or organic matter) or by chemical precipitation. These rocks often contain fossils and exhibit layering (strata). Examples include sandstone (cemented sand grains), shale (compacted clay and silt), and limestone (primarily composed of calcite, often formed from marine organism shells). Sedimentary rocks are very common in the Madison area’s geological context.
• Metamorphic Rocks: Formed when existing igneous, sedimentary, or even other metamorphic rocks are transformed by heat, pressure, or chemical reactions, without melting completely. This process can change the minerals present, create new minerals, and alter the rock’s texture. Examples include marble (metamorphosed limestone), slate (metamorphosed shale), and gneiss (often formed from granite under intense pressure).

The Rock Cycle

The rock cycle is a fundamental concept in earth science, illustrating how the three rock types are interconnected and how processes like weathering, erosion, melting, and metamorphism transform one type into another over geological time. For instance, an igneous rock like granite can be weathered into sediments, which form sandstone; sandstone can be subjected to heat and pressure to become quartzite (a metamorphic rock); quartzite could melt to form magma, which then cools into new igneous rock. This continuous process highlights the dynamic nature of Earth’s crust.
