Zusammenfassung |
Depth distribution of radiogenic heat sources in continental crust is an
important parameter that controls its thermal structure as well as the
mantle heat flow at the base of continental lithosphere. Various models for
the depth distribution of radiogenic heat sources have been proposed.
Starting from constant and exponential models based on linear heat flow–heat generation relationship the present-day layered models integrate
crustal structure and laboratory measurements of radiogenic heat sources in
various exposed rocks representing crustal composition. In the present work,
an extended entropy theory formalism is used for estimation of radiogenic
heat sources distribution in continental crust based on principle of maximum
entropy (POME). The extended entropy principle yields a constant heat
generation model if only a constraint given by total radiogenic heat in the
crust is used and an exponential form of radiogenic heat sources
distribution if an additional constraint in the form of a second moment is
used in the minimization of entropy. |
