Geosonnet 66

A Solo smuggler must hide his freight.
Hidden compartments store his shady wares.
So when a mineral conceals hydrate
There must be secret structure which ensnares
The water slipping through the MOHO line.
A fugitive from oceanic law.
How does an olivine the H confine
And store in crystal structure lattice flaw?
The brucite sidekicks are forsterite’s foils
Magnesium, low silica create
Tetragonal sites vacant, H embroils
This nominally dry mantle substrate
    Hot hydrogen won’t change the warring stars
    And yet it could distinguish us from Mars.
