Geologic Map of West Virginia. West Virginia's geologic history stretches back into the Precambrian, and includes several periods of mountain building and erosion. At times, much of what is now West Virginia was covered by swamps, marshlands, and shallow seas, accounting for the wide variety of sedimentary rocks found in the state, as well as its wealth of coal and natural gas deposits.
Magma rich in silica and poor in dissolved water is most easily cooled rapidly enough to form volcanic glass. As a result, rhyolite magmas, which are high in silica, can produce tephra composed entirely of volcanic glass and may also form glassy lava flows. [2] Ash-flow tuffs typically consist of countless microscopic shards of volcanic glass. [3]
Obsidian (/ ə b ˈ s ɪ d i. ən, ɒ b-/ əb-SID-ee-ən ob-) [5] is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock . [ 6 ]
There are listings in every one of West Virginia's 55 counties. Listings range from prehistoric sites such as Grave Creek Mound , to Cool Spring Farm in the state's eastern panhandle, one of the state's first homesteads, to relatively newer, yet still historical, residences and commercial districts.
Tachylite from Kīlauea volcano in Hawaii (view is about 9 cm across) Tachylite (/ ˈ t æ k ə l aɪ t / TAK-ə-lyte; also spelled tachylyte) is a form of basaltic volcanic glass. This glass is formed naturally by the rapid cooling of molten basalt. It is a type of mafic igneous rock that is decomposable by acids and readily fusible.
The glass shards (mostly brown) sometimes become welded together when the deposit is still hot, and can be deformed by flow and compaction about crystal fragments (clear). Ignimbrite is primarily composed of a matrix of volcanic ash ( tephra ) which is composed of shards and fragments of volcanic glass, pumice fragments, and crystals.
Ugly Mountain is a summit in Pendleton County, West Virginia, in the United States. [1] With an elevation of 2,598 feet (792 m), Ugly Mountain is the 507th highest summit in the state of West Virginia. [2] Ugly Mountain is a volcanic neck with a diatreme breccia that formed during the Middle Eocene. [3]
