A – Distribution <strong>of</strong> <strong>the</strong> assignedpermeabilities; B – distribution <strong>of</strong> temperature; C – Darcy fluxes and vectors; D – distribution <strong>of</strong> <strong>the</strong> tracer. A, B, and D show fluid flowlines. Note virtually no differencewith Figure 7.5 in terms <strong>of</strong> temperature distribution. The model does not represent <strong>the</strong> present-day hydrogeological regime in areas proximal to <strong>the</strong> Four Mile and Beverleydeposits.Page 92 <strong>of</strong> 151
