What is pegmatite texture?
A pegmatite texture in a rock is a course-grained Igneous Rock. Granite Pegmatite is a common Igneous rock
Is beryl a mineral or rock?
Beryl can be found in alluvial deposits from erosion out of pegmatite veins. This is the easy way, sorting through sand and gravel. The hard way is to attack the granitic pegmatite with tools and see what's inside.
What is the chemical composition of pegmatite?
Pegmatite is a light-colored, extremely coarse-grained intrusive igneous rock. It forms near the margins of a magma chamber during the final phases of magma chamber crystallization. It often contains rare minerals that are not found in other parts of the magma chamber.
What are the colors in a pegmatite rock?
Beige, dark green, dark grey, dark red, light beige, green, light green, and light grey.

How does pegmatite rocks form?
Being an igneous rock, a pegmatite can have numerous "origins". A pegmatite is thecoarsest of the igneous rock types, with the largest crystals, resulting from a very slow rate of cooling. At the Boomer Mine in the South Park of Colorado, a single beryl (beryllium aluminum silicate) crystal was mined from the pegmatite rock there which was six feet in diameter and nearly nine feet long. The Boomer Mine pegmatite is part of the Pikes Peak batholith. Unfortunately, it was uncovered on a weekend when the resident geologist was off work and the miners put the crystal into the mills crusher!! It should have gone to the Smithsonian Institute. You may know beryl as the semiprecious stone "aquamarine".

What rock has larger crystals than basalt and granite?
A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.
