No. Contact metamorphism will most likely alter shale into hornfels. Phyllite is regionally metamorphosed slate, and slate is metamorphosed shale.
Hornfels is a type of rock that is metamorphic. They usually have bands and fine grain, and can come in different colors, such as light gray and dark gray.
I too would like an answer to this question as it seems hornfels could be of varying grade dependant on the temperature. The facies of contact metamorphism progress in temperature at relatively low pressure from the Albite-Epidote Hornfels Facies to the Hornblende Hornfels Facies, to the Pyroxene Hornfels Facies. It seems that hornfels do have differant grades.
- Amphibolite - Eclogite - Gneiss - Greenstone - Hornfels - Marble - Migmatite - Phyllite - Quartzite (Metaquartzite) - Schist - Slate - Soapstone
They are all metamorphic rocks.

No. Contact metamorphism will most likely alter shale into hornfels. Phyllite is regionally metamorphosed slate, and slate is metamorphosed shale.
Slate, gneiss, skarn, phyllite, hornfels, amphibolite, schist, quartzite, marble, and granulite are all metamorphic rocks.

No. Quartzite and slate are two different varieties of metamorphic rock. They are quite different.
Typically an opaque green, greenish-brown, brown or black color.
