WebFelsic igneous rocks with a large amount of non-ferromagnesian minerals will be light in colour. ... Rocks having crystals that are visible to the unaided eye have a phaneritic (or coarse-grained) texture (from the Greek word phanerós, meaning “visible”). The rocks in Figure 3.3 all have a phaneritic texture. WebFor 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. earthquake gif images WebFor phyllosilicate-rich rocks, the term schist is reserved for medium- to coarse-grained varieties, wheras finer-grained rocks are termed phyllites or slates.

If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic.

WebIn igneous rocks, these textures are shown by granites and felsites and hence are also often named as granitic and felsitic textures. In the granitic texture, the constituents are either all coarse grained or all medium grained and the crystals show euhedral to subhedral outlines.
