Lepidoblastic Texture

A lepidoblastic texture is a metamorphic texture in which platy or tabular minerals are aligned to produce a planar fabric. Slate, phyllite and schist all have lepidoblastic textures. This texture is due to the parallel orientation during recrystallization of minerals with a flaky or scaly habit, e.g. mica and chlorite.
