Hornfels: Metamorphic Rock
What is Hornfels? Hornfels is a fine-grained metamorphic rock that was subjected to the heat of contact metamorphism at a shallow depth. It was "baked" by heat conducted from a nearby magma chamber, sill, dike, or lava flowmon temperatures for the formation of hornfels range from about 1300 to 1450 degrees Fahrenheit (700 to 800 degrees Celsius).

Metamorphic Rocks: Formation, Types, Uses, Example
Metamorphic rocks are type of rock that formed when pre-existing rocks (parent rocks) undergo significant physical or chemical changes under high pressure and temperature, without melting completely. This process, known as metamorphism, alters the texture, mineralogy, and composition of the original rock, creating a new rock type.Metamorphism, Literally Means …
