- Flow_banding abstract "Flow banding is a geological term to describe bands or layers that can sometimes be seen in rock that formed from the substance molten rock or magma.Flow banding is caused by friction of the viscous magma that is in contact with a solid rock interface, usually the wall rock to an intrusive chamber or, if the magma is erupted, the surface of the earth across which the lava is flowing.The friction and viscosity of the magma causes phenocrysts and xenoliths within the magma or lava to slow down near the interface and become trapped in a viscous layer. This forms laminar flow, which manifests as a banded, streaky appearance.Flow banding is the result of a process of fractional crystallization that occurs by convection if the crystals that are caught in the flow-banded margins are removed from the melt. This can change the composition of the melt in large intrusions, leading to differentiation. In layered intrusions, flow banding can occur with crystal accumulation, forming pseudo-sedimentary structures. Flow banding can also occur due to disturbances in the field of flow, thus forming a haemotomtic flow band. These are common in the region of upper Iceland. There are many good Icelandic videos in which this rare phenomenon can be observed.".
