A tube-shaped structure carved by magma is called a "dike." Dikes form when magma intrudes into existing fractures in the surrounding rock and solidifies, creating a vertical or near-vertical wall of igneous rock. Alternatively, if magma fills a space and solidifies in a horizontal manner, it is referred to as a "sill." These geological formations are important for understanding volcanic activity and the movement of magma within the Earth's crust.
As magma rises, it carves a tube-shaped structure called a "magma conduit" or "volcanic conduit." This structure allows the magma to travel from the magma chamber beneath the Earth's surface to the volcano's vent. As pressure builds, it can lead to volcanic eruptions when the magma escapes through the conduit.
Lava tubes.
As magma rises, it carves a tube-shaped structure called a "magma conduit" or "volcanic conduit." This structure allows the magma to travel from the magma chamber beneath the Earth's surface to the surface during a volcanic eruption. The conduit can solidify into igneous rock once the magma cools and crystallizes.
The tube-shaped structure that forms after magma rises is called a "magma conduit" or "volcanic conduit." This passage allows magma to travel from the magma chamber beneath the Earth's surface to the surface, where it can erupt as lava. Over time, the conduit can solidify and become a part of the volcanic structure.
When magma rises through the Earth's crust, it forms a tube-shaped structure known as a "magma conduit" or "magma chamber." This conduit serves as a pathway for the magma to move from the mantle or deeper crust to the surface, often leading to volcanic eruptions. As the magma accumulates in the chamber, it can create pressure that eventually results in explosive volcanic activity.

As magma rises, it carves a tube-shaped structure called a "magma conduit" or "volcanic conduit." This pathway allows the magma to move upward from the magma chamber beneath the Earth's surface towards the surface, where it can erupt as lava. The conduit can also help form various volcanic features, such as volcanoes or lava domes, depending on the composition and behavior of the magma. Over time, the solidified magma in the conduit can create a central vent or pipe structure within the volcano.

Resurgent dome is the term used to describe a structure that forms when magma re-enters a magma chamber, causing the floor of the caldera or crater to lift. This uplift creates a dome-shaped structure within the caldera.
batholiths
The magma in a sill that pushes up to form a dome-shaped rock structure is called laccolith. Laccoliths form when magma intrudes between layers of sedimentary rock and causes the overlying rocks to arch upwards, resulting in a dome-like structure.
An igneous intrusive feature that forms from a lens-shaped mass of magma that arches the overlying strata upward is called a laccolith. Laccoliths typically create a dome-like structure as the magma pushes the surrounding rock layers upward. They are often associated with volcanic activity and can vary in size.
The structure you are describing sounds like a volcanic dome or plug. These are created when highly viscous magma solidifies near the surface, causing the ground above to be pushed upward. Over time, erosion may expose the magma structure, forming a mushroom shape.
