Magmatic Intrusion Structure

Any domical or ringlike structure produced by surface manifestation of a subsurface magmatic intrusion. Intrusions are subsurface concentrations of magma that have locally uplifted the soil but do not erupt, a mechanism reported for terrestrial laccoliths (Pollard and Johnson 1973).



Terrestrial laccoliths and lunar putative intrusive domes have in common that they are characterized by elongated outlines (circularity <0.8) and very low slope (<0.9°). Terrestrial laccoliths are 1–10 km in radius or length and 10–100 m in thickness (Michaut 2010).


Surface manifestations of subsurface intrusions where a subsurface accumulation of magma caused an up-doming of the bedrock layers (Lena et al. 2013). Fractures probably formed by the tensional stress caused by flexure of the laccolith overburden.


A pressurized magma that penetrates between layers of solid rock may change the shape of these...
