Geosonnet 39



The Kelly Caves, where bushrangers once hid
Were shelter of a venerated kind.
Cro-Magnon ancestors did not forbid
Shelter, and art, in caverns thus confined.
But holes in rock as habitat might date
To early in our planet’s history
The microbes and the cavemen can relate
Archean prelude Pleistocene story
Both sheltered in a mineral cavity.
The upside-down microstromatolites
Cling to the roof, outlaws of gravity
Not methane, autotroph metabolites
   These outlaws hid beneath the algal mats
   Kerogenated troglodytic bats

Geosonnet 38



A Daal is more than just a spicy meal
Tsunamis, mighty earthquakes it informs
Shear diffusivity it can reveal
The mechanism by which it deforms.
The humble lentil, pressed into a box
begins to slide, but not on just one plane
The shear migrates when grain rotation locks
Without localization of all strain
The superlentils, strong but not congealed
Not Marvel men with tights and curried food
Anastamosing fabrics are revealed
Transposing when the pulses become skewed.
A legume in the larder shows the way
A devastating earthquake slides today.
