Geosonnet 22

From flood basalt hot sulfur will exhale,
Across the dying planet, smog bank draped
The genie left the bottle, empty grail,
No evidence what long ago escaped.
The lava flows forget what they degassed
A fleeting daydream, lost with time’s progress
But though a hundred million years have passed
The clinopyroxene preserves the S.
Partitioning experiments defined!
A synchrotron or ion probe can see
The sulfur clouds to which we once were blind
Are quantified now, analytically.
   Sulfurous magma wrecked the biosphere
   While clean eruptions let life persevere.
