Your paradigm requires anti-gravity.

What?

You say the planet grows , so I ask , " Why is the oldest rock
mafic ? And , how does the evolution of continental crust arise
from oceanic ? Your paradigm implies that the granite was always
there , beneath the oceanic crust , just waiting for expansion to
allow it to surface .


But instead of  contorting and murdering logic by putting
it through the thermal mincer of  convection like you do, gravity acts
directly on the mass of the planet to determine where and when it will
split, .. and you can read this by looking at the geology as it
develops through time.

Yes , lets look at the record through time . Does the chemistry
indicate an increase in ocean volume or decrease in trace element
percentage with time?  The volume of water has stayed the same.

Hardly!

There is no spike in the geologic record indicating an infusion
of trace elements or a dilution caused by new ocean water . Nor
are there indications of primarily deep water deposits that would
indicate water volume has changed over time . Since we know the
planet wasn't covered by water , " Where is the geochemical evidence
for your paradigm ? "


The fact is that trace element analyses have shown that
there has been a progressive enrichment that is consistent
with a constant radius Earth and recycling through both crust and
mantle. Had water volume increased with time trace markers
would have been more concentrated in the past and show
dilution today.

Not if the trace element are brought to the surface.

You lack a basic understanding of this subject .

All *you* can do is make models and rubber
your numbers to suit.  The rocks of the planet do not lie,

You either have no idea what they say or you ignore the
chemical evidence.( Sr87/Sr86... 4Rb87/Sr86 ). These analyses
on Archaen rock show the crust was mafic.

If older crust was " heavier "  why.. did " lighter " granitic crust
spend 2.5 by under this heavier crust before it finally made
its way to the surface ? Doesn't make sense , does it ? Just
another inconsistency in EE.

granitic crust was not under. It did not exist. Granitic rocks formed
and got emplaced gradually as the surface of Earth expanded.

Again , you have an insufficient understanding . Differentiation of
mafic crust and its evolution into granite requires heat and pressure
to melt that mafic crust . If the planet is expanding it is releasing
the required heat before it can melt .

The fact is that crustal collisions in the Archaen piled up mafics
until
they were thick enough that the pressure of the overburden melted
these rocks
and the first granites formed by differentiation .




Fact is , sial is the product of differentiation and slow enrichment
 by recycling of oceanic crust .


More adhoc.

Why do you think I recommended you find a Chemist ?
