The zircon and monazite saturation systematics of the HHL show that the residence time of the parental anatectic melts in their source was short of the order of a few thousand years and certainly shorter than 50 000 years (Ayres et al. 1997). This agrees well with our model results of thin sills intruded at intervals of 20 00060 000 years.
