Could contact metamorphism change a shale into a phyllite?
Yes, contact metamorphism can change a shale into a phyllite. Shale is a fine-grained sedimentary rock that can undergo low-grade metamorphism when exposed to high temperatures and pressures near a magmatic intrusion. This process can transform the shale into a phyllite, which is a low-grade metamorphic rock with a glossy sheen and wavy foliation.
Which type of metamorphism is most likely to change shale to hornfels?
Contact metamorphism is most likely to change shale to hornfels. This process occurs when rocks are subjected to high temperatures and pressures due to contact with a magma intrusion, leading to the recrystallization of minerals in the original rock. Hornfels is typically formed under these conditions and is characterized by a fine-grained, non-foliated texture.
Why is foliation more likely to occur during mountain building than through the contact of rock with magma?
Foliation is more likely to occur during mountain building rather than through the contact of rock with magma because of the stress that is developed during mountain building. This refers to the action on a plane as the force applied per unit area of the plane.
Why doesn't metamorphism occur when rocks come in contact with magma?
Metamorphism does occur when rocks come in contact with magma but it is very localised. It is contact metamorphism and a close look with a hand lens will normally show a change to the rock, sometimes only millimetres wide.
What does the radiometric date of metamorphic rock most likely represent?
heated during metamorphism

Ask us anythingAt which location is contact metamorphism least likely to occur?
Contact metamorphism is least likely to occur at locations where there is little to no intrusion of magma near the Earth's surface. In areas with minimal igneous activity and no heat source to drive the metamorphic changes, contact metamorphism is less likely to take place. Generally, regions located far away from tectonic plate boundaries or volcanic hotspots are less prone to experiencing contact metamorphism.

Hornfels is typically formed under these conditions and is characterized by a fine-grained, non-foliated texture.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism between them?
Sedimentary rock and igneous rock would most likely have a zone of contact metamorphism between them. When molten magma intrudes into the surrounding rock, the heat and fluids released can alter the mineral composition of the adjacent rocks, leading to contact metamorphism.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism?
shale and sandstone
Which type of metamorphism is most likely to occur along the fault line?
Dynamic Metamorphism >.<

If the sedimentary rock limestone is subjected to metamorphism what metamorphic rock will likely form?
Limestone can metamorphose into marble, a regional metamorphic rock, or into skarn, a contact metamorphic rock.
A rock from interlocking crystals that are not lined up?
The rock is likely a type of metamorphic rock called a mylonite, which forms from intense deformation. The crystals are not aligned due to the intense shearing forces during metamorphism, causing the grains to rotate and create a foliation. This unique texture distinguishes mylonites from other types of rocks.
Which kind metamorphic rock most likely form in the high temperatures and pressures?
High temperatures and pressures are associated with the formation of regional metamorphic rocks such as schist and gneiss. These rocks form deep within the Earth's crust where tectonic forces are intense, leading to the recrystallization of minerals and the development of foliation.
Which would you expect to cause the greatest amount of contact metamorphism an intrusion of basaltic magma or an intrusion of rhyolitic magma?
An intrusion of basaltic magma would likely cause greater contact metamorphism compared to an intrusion of rhyolitic magma. Basaltic magma has higher temperatures and higher fluidity, allowing it to heat surrounding rocks more effectively and induce more intense metamorphic changes.
