Trachyte - Wikipedia
Trachyte is the usual silica-rich end member of the alkaline magma series, in which alkaline basaltic magma experiences fractional crystallization while still underground. This process removes calcium, magnesium, and iron from the magma to give it …
Trachyte : Composition, Formation, Classification and Uses
2023年10月20日 · Trachyte is a type of volcanic rock that falls within the category of extrusive igneous rocks. It is characterized by its unique composition and texture, which make it distinct from other volcanic rocks like basalt, andesite, and rhyolite.
Trachyte | Properties, Uses & Formation | Britannica
Trachyte, light-coloured, very fine-grained extrusive igneous rock that is composed chiefly of alkali feldspar with minor amounts of dark-coloured minerals such as biotite, amphibole, or pyroxene. Compositionally, trachyte is the volcanic equivalent of the plutonic (intrusive) rock syenite.
Understanding Trachyte, a Fine-grained Volcanic Rock
2023年9月27日 · Trachyte is fine-grained, usually light-colored volcanic or extrusive igneous rock. It has an intermediate composition with its essential alkali feldspar, lesser plagioclase, and minor mafic minerals. Also, it may have none to a small amount of quartz.
Trachyte - Igneous Rocks - Sandatlas
Trachyte is a fine-grained and generally light-colored volcanic rock that usually has a rough surface to the touch which is the reason it was given that name (trachys is ‘rough’ in the Greek language).
Geology - rocks and minerals - University of Auckland
Trachyte is an extrusive rock, belonging to the alkali series of intermediate volcanic rocks. The major mineral component of trachyte is alkali feldspar (e.g. orthoclase), and it generally contains no quartz.
Trachyte - ALEX STREKEISEN
Trachytes are composed chiefly of alkali feldspar with minor amounts of dark-coloured minerals such as biotite, amphibole, or pyroxene. Compositionally, trachyte is the volcanic equivalent of the plutonic (intrusive) rock syenite.
Trachyte - MiMaEd
One such intriguing geological specimen is Trachyte, a volcanic rock with unique characteristics and widespread applications. In this in-depth guide, we will explore the various aspects of Trachyte, from its composition and texture to its origin, classification, and practical uses.
Trachyte - Dedalo Stone
Trachyte is an extrusive igneous rock characterized by its porphyritic texture and high silica content, typically giving it a light color that can range from gray to white, with shades of pink and light green.
What Is Trachyte? - Spiegato
Trachyte is an extrusive igneous volcanic rock. Extrusive refers to the ejection of the rock from the earth during an eruption of magma, and igneous refers to the rock having solidified and later cooled from lava. Its texture can be finely grained or rough. The trachyte is primarily composed of minerals that are rich in alkali elements.
