Could contact metamorphism change a shale into a phyllite?
No. Contact metamorphism will most likely alter shale into hornfels. Phyllite is regionally metamorphosed slate, and slate is metamorphosed shale.
Is granite formed from the metamorphism of a shale?
No. The metamorphism of shale forms slate. Granite is formed when high-silica magma cools underground.
What is hornfels made of?
Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. Because pressure is not a factor in the formation of hornfels, it lacks the foliation seen in many metamorphic rocks formed under high pressure and temperature regimes. Pre-existing bedding and structure of the parent rock is generally destroyed during the formation of hornfels.
Is a rock called shale formed from the skeletons of the ancient coral animals?
No . Shale is formed my the metamorphism of the rock - Slate
What rock was once shale?
Shale is a sedimentary rock that can transform into other types of rock through the process of metamorphism. Under heat and pressure, shale can turn into slate, while further metamorphism can result in the formation of phyllite, schist, and gneiss.
Could contact metamorphism change a shale into a phyllite?
No. Contact metamorphism will most likely alter shale into hornfels. Phyllite is regionally metamorphosed slate, and slate is metamorphosed shale.
During the intrusion of the Palisades Sill contact metamorphism changed sandstone and shale into what?
Hornfels
What process forms hornfels?
Hornfels is formed when mudstone or shale come in contact with a hot igneous body and metamorphic rock. This process is called contact metamorphism.
What is a nonfoliated rock formed by contact metamorphism of a shale or mudstone?
Contact metamorphism takes place locally near igneous intrusions. It is caused by low to moderate pressure, intense heat, and reactions to magma that is being metamorphosed. When contact metamorphism takes place with mudstone or shale (sedimentary rocks) slate is formed. The mudstone or shale is the parent rock or protolith.
Describe the metamorphism of shale and the rock sequence involved in that metamorphism?
Shale is a sedimentary rock. In increasing metamorphism, the sequence begins with shale and leads to phyllite, schist, then gneiss.
Which sedimentary rock is most likely to be changed to slate during regional metamorphism?
Shale.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism between them?
shale and sandstone
What is the name for the rock hornfels?
sandstone, shale,slate, limestone and diabase
