Related to diapiric: piercement


A geological structure formed when a mass of material of high plasticity and low density, such as salt, gypsum, or magma, pushes upward into overlying strata.

[French, from Greek diapeirein, to push through : dia-, dia- + peirein, to pierce; see per- in Indo-European roots.]
