Abstract Recent exchanges concerning methods for extracting thermal histories from low temperature thermochronology data do not address key limitations imposed by the nature of system response. Thermochronology data in isolation cannot define periods when samples were cooler and subsequently reheated. This can only be defined with the aid of constraints from geological evidence. The common assumption of slow continuous cooling is clearly not appropriate in many situations, and cooling rates derived from such studies have little relevance to geological processes. We suggest a revised approach, which focuses on the information contained in the data.
