Rhyolite is an extrusive, silica-rich igneous rock. Rhyolite has a similar composition and appearance to granite. However, rhyolite forms as a result of a violent volcanic eruption, while granite forms when magma solidifies beneath the Earth's surface.
Rhyolite is also high in gas content. Gases rapped within the lava as it cools form vugs or gas-filled bubbles. When water containing dissolved minerals fill these vugs, conditions may be right for crystals and gemstones to grow. Topaz, agate, jasper, red beryl, and opal are a few of the crystals and gems that occur in rhyolite.

Rhyolite. Rhyolite is a relatively rare volcanic rock with the same mineral makeup as granite.. While it most commonly occurs with obsidian, rhyolite also serves as the parent rock for the formation of Oregon Opal. Because rhyolitic lava is so thick, it seldom makes it to Earth’s surface, but when it does, it piles over volcanic vents without flowing away, forming a dome.

What is Rhyolite? Rhyolite is an extrusive igneous rock with a very high silica content. It is usually pink or gray in color with grains so small that they are difficult to observe without a hand lens.Rhyolite is made up of quartz, plagioclase, and sanidine, with minor amounts of hornblende and biotite.Trapped gases often produce vugs in the rock.

Rhyolite, extrusive igneous rock that is the volcanic equivalent of granite.Most rhyolites are porphyritic, indi ing that crystallization began prior to extrusion. Crystallization may sometimes have begun while the magma was deeply buried; in such cases, the rock may consist principally of well-developed, large, single crystals (phenocrysts) at the time of extru
They are made up of minerals. Minerals are the building blocks of rocks. A rock can be made up of many different minerals. Chemical Formulas In Minerals. Each mineral has a particular chemical make up. While most minerals are compounds of two or more elements, some minerals are made up of a single element.
Rhyolite rocks bear a striking resemblance to granite, due to being classified as felsic rocks, except that rhyolite has a fine-grained texture with phenocrysts, which are small crystals sometimes embedded within the rock. The minerals that make up the composition of this rock are mica, feldspar, quartz, and hornblende.
A rock is an aggregate of minerals and does not need to have a specific chemical composition. A crystal is a solid whose atoms are arranged in a 'highly ordered' repeating pattern. These patterns are called crystal lattices. If an object has its atoms arranged in one of seven crystal lattice patterns, then that object is a crystal.
