Segment tip geometry of sheet intrusions, II: Field observations of tip geometries and a model for evolving emplacement mechanisms
Igneous sheet intrusions are segmented across several orders of magnitude, with segment tip geometry commonly considered indicative of the propagation mechanism (brittle or non-brittle).Proposed propagation mechanisms are inferred to represent host Pedal Arm Gear Set rock mechanical properties during initial magma emplacement; typically, these mode
