Supplemental Material: Intrusion tip velocity controls the emplacement mechanism of sheet intrusions

Geological map of the Highwood Mountains of Montana, western United States; uninterpreted, high-resolution images shown in Figure 2; Jupyter notebook used to perform thermal modeling and fracture tip velocity estimates; Excel spreadsheet with field constraints (i.e., fracture aperture and distance of aperture measurement to fracture tip) used to estimate fracture tip velocities.
