The Autun oil shale deposit is a sedimentary basin containing oil shale of the Autunian age (between 299 and 282 million years old) in the vicinity of Autun in Saône-et-Loire, in the center-east of France.
The extraction of the shale commenced in 1824 at Igornay. Oil shale production began as early as 1837 for public lighting purposes, with facilities undergoing continuous improvement to diversify production. The largest of these facilities was the Télots mine, which was equipped with a refinery in 1936 and employed several hundred workers to produce automobile fuel. This mine was the last to close in 1957. The total production of the deposit is estimated at 13 million tons.
The vestiges of this industrial activity, in the form of ruins and slag heaps, persist in the early 21st century, particularly in the villages of Dracy-Saint-Loup, Saint-Forgeot, and Tavernay.
