Mixing calculations illustrate the possible effects of bulk assimilation of continental crust.
The derivation from or contamination with crustal material explains the observed similarity of the multi-element patterns to typical upper continental crust.
It is therefore likely that generation of the widespread intermediate-silicic magmas represents an early stage in the formation of continental crust.
This finding has important implications for the growth of the continental crust.
The larger modelled upper continental crust component is also consistent with the relative abundance of detrital mica of possible extra-basinal origin.
This is in agreement with return to more mafic detritus and the proposed increased upper continental crust contribution, together at the expense of felsic detritus.
Inevitably then, over the course of time, the volume of continental crust builds up.
The origin and accretionary history of the continental crust has long been debated by earth scientists.
