Collateral Damage: Fracking (5)

Created on: Thursday, February 20, 2020
Collateral damage is a series of prints, paintings and drawings based on the geology of Marcellus shale of the North Eastern US, and the fossil record embedded in it.

Marcellus shale dates from 400 million years ago (mya) and is deep below the
ground we walk on.

Fracking (hydraulic fracturing) of this dark fragile sediment yields commercial
quantities of gas that is mined extensively across Pennsylvania and beyond.

Shale was formed from deposits of organic matter in the deep seas that covered
the Earth. It is rich in fossils. When fracking occurs the fossils are destroyed.
  • Fracking: Marcellus shale
  • Crinoid sp., 425 mya. Related to starfish, crinoids had ‘stems’ of 40m (130ft)
  • Devonian fishes, 390 mya. The Devonian is often described as the era of fishes
  • Marcellus shale III
  • Marcellus shale IV
