TerraMod Basin Modelling Software Demonstrationof Thrust Models

TerraMod Thrust Modelling u Event Type = Thrust u Emplaces Older Layers on Younger u Define:  Timing and Duration of Thrusting  Layers Cut Out by Thrust  Transient Heat Flow During Thrusting

No Excess Pressures Prior to Thrusting and Associated Rapid Sediment Loading

Review Each Time Step for Development of Excess Pressures Associated With Thrust Loading

Slight Elevation of Pressures Above Hydrostatic (Note Auto-Scaling on X-Axis)

Development of Early Excess- Pressures From Rapid Sediment Loading Ahead of Thrust Front

Large Increase in Excess- Pressures (>30,000 kPa) Associated With Emplacement of Thrust Sheet

Excess-Pressures Decline to >5000 kPa

Continued Declining of Excess-Pressures

Declining Excess-Pressures Within 6 Myrs. After Thrust Emplacement

Increased Heating Rate and Peak Oil Generation Associated with Thrust Emplacement
