Mafic Vs. Felsic Rocks: Know the Difference - ScienceStruck

The most common examples of rocks classified as Mafic are gabbro, dolerite, and basalt. Silica content in Mafic rocks is around 50% by weight. Most of these rocks are gray though Mafic rocks are also found in brown, green, and even black colors.

Igneous rock (derived from the Latin word ignis meaning fire), ... Basalt is a common extrusive igneous rock and forms lava flows, ... crystal content and the amount of silica. High-temperature magma, most of which is basaltic in composition, behaves in a manner similar to thick oil and, as it cools, treacle.

Basalt / basaltic lava. Photos and brief explanation

Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene and iron ore (titaniferous magnetite).Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro.

Igneous rock - Wikipedia

Andesite (/ ˈ æ n d ɪ s aɪ t / or / ˈ æ n d ɪ z aɪ t /) is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. In a general sense, it is the intermediate type between basalt and rhyolite, and ranges from 57 to 63% silicon dioxide (SiO 2 ) as illustrated in TAS diagrams .
