Geosonnet 58

Three narratives, like Roshomon they vie,

To frame suboceanic mantle growth.
Sea water infiltration cannot tie
The isotopes and concentrations both.
A diff’rent melt, cryptic in its disguise
Will spin the tale to take the starring role.
From clinopyroxene we can surmise
The melting source, not multiple, is sole.
Assimilation, favored by the Borg
Sees itself eating altered seafloor crust
This theory dies, is buried in the morgue
These melts are far too primitive, robust.
     Unlike the movie data can constain
     Remelted sulfides crystallized again.
