Trachyte
Trachyte is a volcanic rock that is primarily composed of alkali feldspar. This attractive mineral is commonly used in stone buildings, all the way back to ancient Rome. Several prominent natural features, including Mount Kilimanjaro, are also predominantly composed of trachyte.

What Is Trachyte?
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.

Trachyte: Mineral information, data and localities.
Trachytic rocks, with felsics comprising 0-5% quartz and alkali feldspar/total feldspar: 0.65-0.9 A group of fine-grained, generally porphyritic, extrusive rocks having alkali feldspar and minor mafic minerals (biotite, hornblende, or pyroxene) as the main components, and possibly a small amount of sodic plagioclase; also, any member of that group; the extrusive equivalent of syenite.

Trachyte
Trachyte is a volcanic rock characterized by a distinctive porphyritic structure, which is evident through the presence of well-formed crystals embedded in a finer groundmass. This structure imparts specific aesthetic qualities and physical and mechanical properties that make trachyte suitable for a multitude of applications.

Trachyte
Chemically, trachyte contains less SiO 2 than rhyolite and more (Na 2 O plus K 2 O) than dacite.These chemical differences are consistent with the position of trachyte in the TAS classification, and they account for the feldspar-rich mineralogy of the rock type.. Trachytes usually consist mainly of sanidine feldspar. Very often they have minute irregular steam …

Geology
Trachyte 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 often displays trachytic texture, where acicular to tabular feldspar phenocrysts align in one direction, suggestive of flow prior to cooling.
