Flow Banding: TLC014

Description
-
This is a rock with many parallel continuous distinct fine layers. There are mainly two colors of layers—black and white, so there may be two major compositions. The pattern is called flow banding.
Flow banding is created in two ways. Mingling of two magmatic liquids in the magma chamber will create such pattern on the wall rock. Or when eruption happens, viscous lava can leave such pattern on the contact surface. Because lava usually cools quickly, the grain size of the rock is small.
