The southern edge of the Rhenish Massif lies in the Northern Phyllite Zone, which has a higher grade than other parts of the zone.

The remainder of the North Col Formation, exposed between on Mount Everest, consists of interlayered and deformed schist, phyllite, and minor marble.
33.
Naming based on texture and a pelite ( e . g ., shale, mudrock ) protolith can be used to define slate and phyllite.
34.
Pucawan Nature Reserve and the southern part of Ingalba Nature Reserve have an Upper Ordovician geology of quartzite, shale, slate, phyllite and schist.
35.
The Kab Formation consists of dark grey sandy sericitic schists, interpreted as metamorphosed terrigenous rocks, acid volcanic rocks and minor beds of marble and phyllite.
36.
The gneiss formed from these sediments created the marble, metaconglomerate, phyllite, quartzite, schist, and slate found in the Blue Ridge and Piedmont areas.
37.
The Tambo is composed mostly of metamorphic rock such as gneiss, mica-schist and phyllite, with a small sector of dolostone just under the peak.
38.
Between, the North Col Formation consists chiefly of biotite-quartz phyllite and chlorite-biotite phyllite intercalated with minor amounts of biotite-sericite-quartz schist.
39.
Between, the North Col Formation consists chiefly of biotite-quartz phyllite and chlorite-biotite phyllite intercalated with minor amounts of biotite-sericite-quartz schist.
40.
Foliated metaconglomerate is created under the same metamorphic conditions that produce slate or phyllite, but with the parent rock ( protolith ) being conglomerate, rather than clay.
