contact metamorphism

The driving force behind this process of contact metamorphism was an increase in temperature.

It occurs as an alteration mineral in contact metamorphism of limestone.

The region has undergone contact metamorphism as magma intruded the area.

As granite formed, secondary rocks were only affected by slight contact metamorphism.

This is geologic evidence of contact metamorphism.

Rocks formed by contact metamorphism may not present signs of strong deformation and are often fine-grained.

The area surrounding the intrusion where the contact metamorphism effects are present is called the metamorphic aureole.

It occurs as veins in serpentinite and contact metamorphism aureoles.

Contact metamorphism is greater adjacent to the intrusion and dissipates with distance from the contact.

Lapis lazuli usually occurs in crystalline marble as a result of contact metamorphism.

It is especially common in hornfels produced by contact metamorphism of pelitic rocks.

Contact metamorphism is caused by the interaction of rock with heat and/or fluids from a nearby crystallizing silicate magma.

Contact metamorphism is the name given to the changes that take place when magma is injected into the surrounding solid rock (country rock).

Around the igneous rock that forms from the cooling magma is a metamorphosed zone called a contact metamorphism aureole.

Hornfels is a rock formed by contact metamorphism, a process that characteristically involves high temperatures but low pressures/depths.

On both contact surfaces of the country rock into which the sill has intruded, evidence of heating will be observed (contact metamorphism).

This contact metamorphism produced a fine mesh of interlocking crystals in the old rocks, generally strengthening them and making them more resistant to erosion.

They were then affected by the intrusion of the granite, which caused further contact metamorphism, locally forming a hornfels, and mineralisation.

Clinohumite is a product of contact metamorphism and is commonly found as indistinct grains embedded in limestone.

Metamorphic rocks (apart from those created by contact metamorphism), are characterised by well-developed planar and linear fabrics.

Vesuvianite occurs as tetragonal crystals in skarn deposits and limestones that have been subjected to contact metamorphism.

Contact metamorphism occurs typically around intrusive igneous rocks as a result of the temperature increase caused by the intrusion of magma into cooler country rock.

It was formed by contact metamorphism in the Tertiary period following the intrusion and uplift of nearby granitic Treasure Mountain dome.

Three types of metamorphism exist: Dynamic metamorphism, Contact metamorphism and Regional metamorphism.
