Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.

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.


Magma that forces its way into rocks and hardens is called a extrusion or fault or unconformity or intrusion?

Magma that forces its way into rocks and hardens is called intrusion.


A laccolith is an example of a?

A laccolith is an example of an igneous intrusion, which is a body of intrusive igneous rock that forms by magma uplifting and pushing overlying rock layers.


Sometimes metamorphic rock is found adjacent to an igneous intrusion as shown in the drawing According to geologists what causes this phenomenon?

Metamorphic rocks found adjacent to an igneous intrusion occur due to the heat and pressure generated by the intrusion. The high temperatures from the magma cause the original rock to metamorphose, resulting in the formation of metamorphic rocks near the boundary of the intrusion.


What statement best describes an igneous intrusion?

An igneous intrusion is formed when molten rock (magma) is forced into preexisting rock and solidifies underground. Over time, the surrounding rock erodes away, exposing the igneous intrusion at the Earth's surface. Intrusions can take various shapes and sizes, such as dikes, sills, and laccoliths.

Why are there no fossils in a intrusion?

If you mean an intrusion via magma/lava, then fossils would not exist due to the fact that most fossils are found in SEDIMENTARY rock, not IGNEOUS (magma/lava rocks).
