Description of Minerals and Rocks - ISGS

If the magma cools slowly, some individual mineral grains have the opportunity to grow larger than others. If the magma cools quickly, as lava or basalt does, the separate mineral grains are small. Igneous rocks are classified on the basis of the size and arrangement of the individual crystals and the kinds of minerals present (table 2).

Types of Rocks and Minerals - Schwinger Geology Project

The chemical makeup of a rock is the composition. It describes either the materials or minerals in a rock. Texture is the rock's quality based on the shapes, positions, and sizes of the grains in the rock. Sedimentary Rock can have a texture of fine-grained, coarse-grained, or medium-grained, depending on the size of the grains that make up the ...

What is the difference between a rock and a mineral?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.

Three Types of Rock: Igneous, Sedimentary Metamorphic AMNH

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon ...

The Rock Cycle National Geographic Society

Nov 21, 2019  There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material.

List of Gemstones: Precious and Semi-Precious Stones - Gem ...

Traditionally, precious stones were the Big Four gemstones — diamonds, emeralds, rubies, and sapphires. Semi-precious stones were everything else. Today, gemologists don’t use these terms because they imply that some gems are better or worth more than others. In fact, some so-called semi-precious stones would be worth far more than so ...

New minerals are created either by rearrangement of mineral components or by reactions with fluids that enter the rocks. Some kinds of metamorphic rocks–granite gneiss and biotite schist are two examples–are strongly banded or foliated. (Foliated means the parallel arrangement of certain mineral grains that gives the rock a striped appearance.)
