\subsection{Thermal constraints on fluid flux}  A requirement of the mixing model is that fluid ascent is fast enough such that heat is largely retained in the fluid and temperature can be used as a conservative tracer for the two components. To a first approximation we can use the estimated temperatures of the fluid end members to constrain the flux of fluid needed to develop a thermal anomaly similar to that observed at Dirtlow Rake. The question is how much fluid and how fast does it have to flow along the fault to (i) heat the rock in the fault zone and (ii) prevent significant heat loss via conduction through the walls of the fault? The problem is illustrated in Figure 9.
