The San Lorenzo Schists are foliated, medium- to coarse-grained, pelitic rocks that generally show a millimeter-scale compositional banding consisting of alternation of lepidoblastic muscovite-biotite domains and coarse-grained granoblastic quartz-rich microlithons.
Additionally, muscovite, chlorite, and graphite minerals define the lepidoblastic texture.
The lepidoblastic texture is also observed due to the orientation of mica minerals.
