basalt and silica

Jun 03, 2019 Andesite is an extrusive igneous rock that is higher in silica than basalt and lower than rhyolite or felsite. Click the photo to see the full-size version. In general, color is a good clue to the silica content of extrusive igneous rocks, with basalt being dark and felsite being light.

    basalt Definition Properties amp Facts Britannica

    Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.

    Basaltic andesite Wikipedia

    Basaltic andesite is a fine-grained igneous rock that is moderately low in silica and low in alkali metal oxides.It is not separately defined in the QAPF classification, which is based on the relative percentages of quartz, alkali feldspar, plagioclase feldspar, and feldspathoids, but would fall in the basalt-andesite field. This corresponds to rock in which feldspathoid makes up less than 10% ...
