Geology - rocks and minerals

Geologists define a rockas: A bound aggregate of minerals, mineraloids, or fragments of other rocks. Chert. The use of the word 'bound' means that a rock must have structural integrity, e.g. an aggregate of sand does not becomea rock until the grains are bound together. Typical binding agents are very fine ...

Crystal Habits and Forms of Minerals and Gems - Geology

Geodic is a habit in which mineral aggregates form a rounded or oblate mass by crystallization on the inside walls of a cavity. Concentric bands or layers of mineral crystals subsequently develop, gradually infilling the cavity without infilling it completely and with a crystal-lined central void. The specimen in the photo is a

Aggregate (geology) - Wikipedia

In the Earth sciences, aggregate has three possible meanings.. In mineralogy and petrology, an aggregate is a mass of mineral crystals, mineraloid particles or rock particles. Examples are dolomite, which is an aggregate of crystals of the mineral dolomite, and rock gypsum, an aggregate of crystals of the mineral gypsum. Lapis lazuli is a type of rock composed of an

Rocks and minerals - British Geological Survey

Rocks are generally made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica, but as grains compacted and cemented into each other.
