Geological Epochs
Variables
Controls the geometry of the half-graben rift basin.
How far the crust stretches, increasing basin accommodation space.
Controls how fast sediment fills the basin (percentage of basin depth).
Controls the thickness of the volcanic Holyoke basalt layer.
Pleistocene glacial scouring removes overlying rock, exposing tilted strata.
Epoch 1: Triassic Breakup
Pangea begins to rift apart. The crust stretches and thins. Adjust the Eastern Border Fault angle and extension displacement, then Simulate to form a half-graben basin where water and sediment can accumulate.
