Lyme Regis Jurassic interbedded fossiliferous shale and limestone. The shale used to be a reservoir rock and can be lit on fire due to its hydrocarbon content.

A lot of companies do shale extraction for hydrocarbons, not a very good way to do it really. Its more costly in terms of production and the environment, but in an ever increasing demand for hydrocarbons I’m willing to guess that tapping in to these resources will make sense economically at some point.

Also, I believe dinoflagellates, along with other marine algae and acritarchs, make up marine shale

Shale is now one of the largest unconventional reservoirs, which as the conventional and easy to access oil and gas are extracted, are becoming more and more important. In the past, and indeed now, there has been lots of controversy concerning the fracking technique used to extract oils, which can lead to pollution of groundwater supplies and micro-earthquakes. As technology evolves however this extraction is becoming more and more safe. By 2020 extraction of “tight gas” from shales will contribute 65% of Americas production, with 2000 trillion cubic feet of reservoired oil and gas in the USA alone.
