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.
What two kinds of adjoining bedrock would most likely have a zone of contact metamorphism between them?
A zone of contact metamorphism typically forms between an igneous intrusion, such as granite or basalt, and the surrounding sedimentary rocks, like shale or limestone. The high temperatures and fluids from the molten rock alter the adjacent sedimentary layers, leading to changes in mineralogy and texture. This process creates a metamorphic aureole characterized by various metamorphic grades surrounding the intrusion.
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.
Is contact metamorphism likely to produce foliation?
Contact metamorphism is less likely to produce foliation compared to regional metamorphism. This is because contact metamorphism involves high temperatures and low pressures, typically resulting in more localized metamorphic changes without the development of the extensive directional alignment of minerals that produces 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.
Which type of metamorphism is most likely to occur along the fault line?
Dynamic Metamorphism >.<
Which bedrock would most likely to contain fossils?
sedimentary bedrock
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.
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 type of bedrock most likely exists in an area that has numerous sinkholes?
Limestone bedrock is most likely to exist in an area with numerous sinkholes. Sinkholes are formed when acidic groundwater dissolves the limestone bedrock, creating underground cavities that can cause the land surface to collapse.
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.
Which rocks are most likely like the bedrock?
nothing
