Geosonnet 48

The garden in which life evolved from slime

Did not have apples, naked girls, delights.

Although the details have been lost to time

clay seems more likely, or serpentinites.

Hydrated mantle min’rals do not tempt

But their kinetics none-the-less intrigue

Relationship twixt rock and sea attempts

at understanding help if we know speed.

The magnetite which serpentine expels

Contains trace actinides which will decay.

The helium which in the crystal dwells

Gives cooling time and late stage growth away.

Three million years ago, when Lucy ran

The final Greek tectonic stretch began.
