Abstract
IN this paper I suggest that Kimmeridge Clay oil shales (and therefore much of the oil in the North Sea) were formed from algal blooms, in an environment between open ocean, and an enclosed marine basin. These conditions favour the production of such blooms, which by deoxygenating and poisoning the water, could temporarily create bottom conditions suitable for the formation of organic-rich sediment
