Short summary
We present the results of a series of experiments that constrain the temperature sensitivity of fission tracks in monazite over geological time. It is concluded that over a heating duration of 10 million years, the estimated closure temperature is < 50 °C and perhaps not much above ambient surface temperatures. Monazite fission track thermochronology has the potential to understand the thermal history and constrain the timing of geological processes in the Earth’s upper crust (< 1–2 km).
