Geosonnet 50



When protolith components decompose
Some isolated grains are left behind
Hydration takes their comrades, spinel knows
Not why it’s been preserved. So can its mind
Be trusted to reveal the deepest Earth
The mantle which exists beneath the crust?
Survivor guilt clouds memories of birth
In which trace elements must earn our trust.
The Tonga Trench serpentinites preserve
Hydration from minimal to complete
Survivor mantle phases there conserve
The elements closed min’rals don’t excrete.
   As long as these survivors can be found
   They will remember stories to expound.
