Rock (geology) Wikipedia

Mar 22, 2003 A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its chemical composition and the way in which it is formed. Rocks form the Earth's outer solid layer, the crust, and most of its interior, except for the liquid outer core and pockets of magma in the asthenosphere.. Rocks

A Glossary of Rock and Mineral Terminology

rock: An aggregate of one or more minerals, (such as granite, shale, marble) or a body of undifferentiated mineral matter, (such as obsidian) or a solid organic material, (such as coal). Rocks fall into three broadly defined groups: igneous, sedimentary, and metamorphic rocks. In some instances a single mineral forms a rock, as calcite

Mineral Wikipedia

A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz, alkali feldspar, and

Examining Minerals and Rocks

a rock, such as grain size, shape, and arrangement. Igneous rocks that crystallize slowly beneath the Earth s surface, typically have visible individual minerals. Extrusive igneous rocks tend to cool much more rapidly, and the minerals grow quicker and can not get as large. They thus have a sugary or fine grained texture.

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.

Aggregates: Mineral information, data and localities.

Aggregate is a broad classification of coarse to medium-grained rock material intended for use in construction. This can include sand, gravel, crushed stone and mine waste, and rocks of all types can be mined or quarried for aggregate making use of what is locally available for local construction rather than bringing higher quality rock from elsewhere at greater expense.

Rocks Mixtures of Minerals. Mixtures or aggregates of minerals are called rocks. There are three basic kinds of rocks, each type is determined by the process by which the rock forms. Igneous Rocks form by solidification and crystallization from liquid rock, called magma. Sedimentary Rocks form by sedimentation of mineral and other rock

Amygdaloidal Structure is that produced in a vesicular rock by filling of vesicles with mineral matter. If a rock has amygdules, use a compound name, for example, amygdaloidal basalt. In Michigan the State Gem pumpellyite variety chlorastrolite and many other interesting minerals are found having filled in these voids.

Sand and Gravel. Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO 2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.
