Poem with Milankovitch cycles

Selwicks Bay

Like veins of fat in a hock of ham
fault lines score down heaved chalk cliffs
and across the thick shore platform.
The flints are uniform, and calcite clefts
indicate the brecciated crush zone
occurring to the south of the west-east
latitude of tectonic disturbance.
It’s highly complex, to say the least.
But there’s a rhythm in the chalk –
soft and harder beds, nodules, wispy marls,
alternating flints – regular as clocks
that mark a record of Cretaceous cycles:
the whole Earth’s orbit accurately ranged,
their frequencies a pace-maker for change.

From Fossil Sunshine, forthcoming from Worple Press
