WebMay 6, 2024 · For example, a coarse-grained, felsic igneous rock is not only a granite, it is an intrusive igneous rock that formed from slow cooling and crystallization of a body of magma within the earth’s crust. The intrusion of large bodies of granite – batholiths – is usually part of the origin of a mountain range. Similarly, a fine-grained, mafic ... Web38 .Rhyolite is a felsic volcanic rock with high silica content, which can make the magma more viscous and prone to explosive eruptions. 39. Shield volcanoes have gentle slopes and tend to erupt effusively, producing mostly lava flows and volcanic gases, rather than explosive eruptions that generate pyroclastic flows and ash clouds.
