  Earth's interior, I posit, is like one of the rare, oxygen-starved "enstatite
chondrite" meteorites (and unlike a more-oxidized "ordinary chondrite" as has
been believed for seventy years). Laboratory-analyzed enstatite-chondrite
samples are comparable to having-in-hand impossibleto- gather deep-Earth
samples. Enstatite-chondrite formation in oxygen-starved conditions caused
oxygen-loving elements to occur, in part, as non-oxides in their iron-alloy.
Observations, consistent with solar abundance and behavior of chemical
elements, lead me to a new interpretation of: (1) Earth's early formation as a
Jupiter-like gas-giant, (2) its decompressionpowered surface geology, (3)
Earth's internal composition, and (4) a natural, planetocentric nuclear-fission
reactor as source of both the geomagnetic field and energy channeled to surface
"hot-spots". I present a unified vision of Earth formation and concomitant
dynamics that explains in a logical and causally related way: (1) fluid
Earth-core formation without wholeplanet melting, and (2) the myriad
measurements and observations, previously attributed to "plate tectonics", but
without necessitating mantle convection.
