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.
There are three main types of slate rock based on their color and composition: black slate, red slate, and green slate. Black slate is the most common type, formed from shale, while red slate gets its color from iron oxide. Green slate is typically formed from chlorite or other minerals containing green pigments.
They are all metamorphic rocks.

Slate, gneiss, skarn, phyllite, hornfels, amphibolite, schist, quartzite, marble, and granulite are all metamorphic rocks.
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.
A nonfoliated rock formed by contact metamorphism of a shale or mudstone is called hornfels. It usually has a fine-grained texture and lacks the layering characteristic of foliated rocks. Hornfels forms when the parent rock is subjected to high temperatures and pressures near a magma intrusion.
Hornfels is a common rock that can form in a contact metamorphic zone. It is typically fine-grained and formed by the heat and pressure from nearby igneous intrusions.
No. Quartzite and slate are two different varieties of metamorphic rock. They are quite different.
The mineral found in granite, andesite, gneiss, and hornfels is feldspar. It is a common mineral in these rock types and can exist in different varieties such as orthoclase, plagioclase, or potassium feldspar.
