A diapir is a geological structure formed by the upward movement of a viscous or less dense material (such as salt or gas) through overlying denser rock layers. This process can occur when the lower material exerts enough pressure to break through the overlying layers, causing them to bulge or dome upwards. Diapirs are often associated with salt, where salt formations can flow and rise through sedimentary layers, creating features that can be seen in the landscape.
