Some igneous rocks have a mix of coarse-grained minerals surrounded by a matrix of fine-grained material in a texture called porphyritic. The large crystals are called phenocrysts and the fine-grained matrix is called the groundmass or matrix.

There are nine main types of igneous rock textures: Phaneritic, vesicular, aphanitic, porphyritic, poikilitic, glassy, pyroclastic, equigranular, and spinifex. Each kind of texture has a variety of different characteristics that make them unique. Properties of Igneous Rock Textures What determines igneous rock texture? Thanks to our Patrons for making Poly Haven possible. Joni Mercado. S J Bennett. Pierre Beranger. Russell Smith. Ryan Wiebe. Max Chandler. Anton. EL Studios - Eric Lalande. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff.

Chapter 3: Igneous Textures • 3.1.1 Rates of nucleation, growth, & diffusion - The relative rates of initial nucleation, crystal growth and diffusion will have considerable influence on the ultimate texture of the resulting rock • However, whichever rate is the slowest will be the overall rate-determining process and exert the most Small rocks ground by ManyTextures.com is licensed under a Creative Commons Attribution 4.0 International License.

The origin of a rock can often be detected from its texture—the sizes and orientations of its mineral or rock fragment components.Most extrusive rocks are fine grained, meaning their mineral components (grains) are less than 1 millimeter in diameter.Lava flow rocks typically have a chilled margin that is very fine grained, or aphanitic. Grain size then increases progressively toward the.

Figure 8.3C, 8.4A, and 8.4C are aphanitic rocks. Because Figure 8.3C and 8.4A are dark in color, they are mafic aphanitic rock called basalt.. The texture of such a rock is referred to as porphyritic, or more.

Each rock name has a specific texture that defines and distinguishes it, with their descriptions listed below. Slate is a fine-grained metamorphic rock that exhibits a foliation called slaty cleavage that is the flat orientation of the small platy crystals of mica and chlorite forming perpendicular to the direction of stress. Intrusive rocks, also called plutonic rocks, cool slowly without ever reaching the surface. They have large crystals that are usually visible without a microscope. This surface is known as a phaneritic texture. Perhaps the best-known phaneritic rock is granite. One extreme type of phaneritic rock is called pegmatite, found often in the U.S.
