Basanite - Wikipedia
Basanite (/ ˈ b æ s. ə ˌ n aɪ t /) is an igneous, volcanic rock with aphanitic to porphyritic texture. It is composed mostly of feldspathoids, pyroxenes, olivine, and calcic plagioclase and forms from magma low in silica and enriched in alkali metal oxides that …
Basanite | Igneous, Volcanic, Magma | Britannica
basanite, extrusive igneous rock that contains calcium-rich plagioclase feldspar (usually labradorite or bytownite), feldspathoid (usually nepheline or leucite), olivine, and pyroxene (titanaugite). Basanite grades into tephrite, which contains no olivine.
Basanite: A Fine-grained Mafic Volcanic Rock - Geology Base
2024年1月28日 · Basanite is a fine-grained, dark-colored volcanic or extrusive igneous rock. Fine-grained means its grains are too small to see without a microscope. Compositionally, basanite is a mafic rock with 45-52% silica. Its main minerals are …

Basanite - an overview | ScienceDirect Topics
The main rock types are silica-undersaturated lava, alkalic basalt, basanite, and melanephenelinite, with lesser amounts of nephelinite, trachyte, and phonolite. Intrusive equivalents occur as alkali gabbro, theralite, and ijolite.
Tephrite, basanite - SpringerLink
With the addition of olivine to this mineral assemblage, the rock is termed as basanite, a term used by the Greeks of classical times to describe touchstones used in testing the purity of alloys of gold and silver. Both tephrites and basanites vary in color from gray to black.
Eruption of ultralow-viscosity basanite magma at Cumbre Vieja
2022年6月8日 · Here we show that this event produced a nepheline-normative basanite with the lowest viscosity of historical basaltic eruptions, exhibiting values of less than 10 to about 160 Pa s within...

basanite - Clark Science Center
Basanite: “A term originally used for a porphyritic basalt containing pyroxene phenocrysts, but later used as a group name for rocks composed of clinopyroxene, plagioclase, essential foids and olivine.”
