Andesite (/ ˈ æ n d ə z aɪ t /) [1] is a volcanic rock of intermediate composition.In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite.It is fine-grained to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende.[2]Andesite is the extrusive equivalent of plutonic diorite.

2023年9月4日 · Andesite is an intermediate sub-alkalic rock with SiO2 contents ranging between 57 and 63 wt. %, and Na2O + K2O contents around 5 wt. %.Intermediate rocks are also characterized by an increased CaO content compared to that in acidic rocks. Similar CaO contents (6 – 7 wt. %) are also typical for diorite – the plutonic equivalent of andesite. The andesite from Šiatorska Bukovinka is ...

What is Andesite? Andesite is the name of a family of fine-grained, extrusive igneous rocks that are usually light to dark gray in color. They have a mineral composition that is intermediate between granite and basalt.Andesite is a rock typically found in volcanoes above convergent plate boundaries between continental and oceanic plates.

2023年7月3日 · Andesite is a fine-grained, intermediate volcanic or extrusive igneous rock. Its composition lies between basalt and dacite, and it has mainly sodium-rich plagioclase and one or more mafic minerals, especially pyroxenes or hornblende.. As McBirney (1989) narrates, Leopold Von Buch coined the term andesite in 1827 to describe …

2021年10月26日 · La andesita es una roca que cristaliza desde un fundido magmático de composición química intermedia, es decir que está en el rango entre el 52% al 63% de sílice (SiO2).

Group - volcanic. Colour - variable, but typically bluish-grey or grey (lighter coloured than basalt). Texture - porphyritic. Mineral content - groundmass generally of pyroxene ( augite) and plagioclase, possibly with minor amounts of amphibole ( hornblende) and glass; phenocrysts of plagioclase and often pyroxene, occasionally olivine or amphibole.

2014年4月19日 · La andesita es una roca ígnea volcánica de composición intermedia, situada entre el basalto (rico en hierro y magnesio) y la riolita (rica en sílice). Su nombre proviene de la Cordillera de los Andes, donde es abundante, aunque también se encuentra en otras regiones volcánicas del mundo.

1. Definition and Composition of Andesite 1.1 What is Andesite? Andesite is a fine-grained volcanic rock (aphanitic texture) that forms through the rapid cooling of magma at the Earth’s surface. Its silica content ranges from 57-63%, placing it between the mafic and felsic rocks. This intermediate silica content gives andesite physical and …
