Flow Texture

flow texture

[′flō ‚teks·chər] (petrology) A pattern of an igneous rock that is formed when the stream or flow lines of a once-molten material have a subparallel arrangement of prismatic or tabular cyrstals or microlites. Also known as fluidal texture.

Flow Texture

the texture of igneous rocks in which the crystals of the rock or the microlites of the groundmass that surround the phenocrysts are oriented along the flow lines of the once molten rock. Flow texture is formed during the movement of viscous solidifying lava. It is characteristic of extrusive rocks, such as trachytes, rhyolites, and obsidian, and of hypocrystalline rocks, such as gabbros and nepheline syenites.
