Abstrakt

The controversy regarding the temperatures of formation of the Paleocene volcanic succession in West Greenland and Baffin Island has just celebrated its 50 years’ anniversary (Drever & Johnston, 1957; Clarke, 1970; Hart & Davis, 1978; Clarke & O’Hara, 1979; Elthon & Ridley, 1979; Francis, 1985; Larsen & Pedersen, 2000). Most recently, Natland (2008) has called the high temperatures calculated for West Greenland into doubt and also presented an alternative model for the formation of the picrites.

Our contribution consists of two parts. First, we attempt to clarify some features of the West Greenland volcanic succession that have not generally been appreciated or have been misinterpreted. Second, we comment directly on some aspects of Natland’s paper.
