Aplite - Wikipedia Aplite ( ˈæplaɪt ) is an intrusive igneous rock that has a granitic composition Aplites are fine-grained to aphanitic (without grains visible to the naked eye) and may consist of only quartz and feldspar or the term may refer to any leucocratic (pale-coloured) minor intrusion of that grain size [1]
Aplite | Igneous Rock, Felsic, Granitic | Britannica aplite, any intrusive igneous rock of simple composition, such as granite composed only of alkali feldspar, muscovite mica, and quartz; in a more restricted sense, uniformly fine-grained (less than 2 millimetres [0 08 inch]), light-coloured, intrusive igneous rocks that have a characteristic granular texture
Aplite: Mineral information, data and localities. - mindat. org Aplites may range in composition from granitic to gabbroic, but the term aplite with no modifier is generally understood to mean granitic aplite or aplitic granite, consisting essentially of quartz, potassium feldspar, and albite
Aplite - Rock Identifier Aplite ( ˈæplaɪt ) is an intrusive igneous rock in which the mineral composition is the same as granite, but in which the grains are much finer, under 1 mm across Quartz and feldspar are the dominant minerals
Aplite - Igneous Rocks - Sandatlas Aplite is a fine-grained igneous rock Most aplites are granitic in composition – chief constituents are feldspars and quartz Aplite is associated with granitic rocks that are similar in composition and they may be associated with pegmatites
Aplite - an overview | ScienceDirect Topics Aplite is defined as a fine-grained light-colored granite that typically consists of quartz and alkali feldspar, often occurring as a component of layered pegmatites where it serves as the substrate for the overlying pegmatite
How to Identify Aplite | Properties, Meaning Uses Aplite ( ˈæplaɪt ) is an intrusive igneous rock in which the mineral composition is the same as granite, but in which the grains are much finer, under 1 mm across Quartz and feldspar are the dominant minerals
