WebOct 25, 2024 · Introduction. Igneous rocks are “fire-born,” meaning that they are formed from the cooling and solidification of molten (melted) rock. The word igneous derives from ignis, the Latin word for “fire.”. Molten rock material is known as magma until it is erupted onto the surface when it then is termed lava. WebThe characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.

Extrusive or volcanic rocks crystallize from lava at the earth’s surface. The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals.

WebJun 3, 2015 · Permeability ranges from 400 darcies in well-sorted, coarse-grained sands to 0.1 darcies (100 md) in very poorly sorted, fine-grained sands. Permeability varies with grain size and sorting because it is controlled by pore-size distribution. Most modern sands are reservoir-quality rock.
