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.

MoreManaging Your Emotions
What makes me angry?
Mostly，l hate when someone tries to make someone else feel bad.
I have to admit that once, when l was actually called names.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
The most postive way of dealing with anger is talking about the problem.
l talk to someone who listens, or l'll write my thoughts down on paper.
Learning how to deal with anger as you're growing up is so important.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
