As nouns the difference between andesite and rhyolite is that andesite is (geology) a class of fine-grained intermediate igneous rock, of volcanic origin, containing mostly plagioclase feldspar while rhyolite is (geology) rhyolitic text is available. One major difference between basaltic and granitic magma is their specific mineral contents basaltic magma contains between 45 and 55 percent silicon dioxide and is high in magnesium, iron and. 18 explain the general differences in silica content and style of volcanic eruption (ie, quiet lava flows versus explosive eruptions of pyroclastics) associated with basaltic magma, andesitic magma, and rhyolitic magma. Reading: dikes and sills dikes dikes can vary in texture and their composition can range from diabase or basaltic to granitic or rhyolitic sills can be confused with solidified lava flows however, there are several differences between them.
