Tertiary fossil forests of the Geodetic Hills, Axel Heiberg Island, Arctic Archipelago / edited by R. L. Christie and N. J. McMillan. Ottawa - Ontario : Energy, Mines and Resources. 227p. : figs., graphs, plates, references, tables ; 28 cm. Bulletin 0068-7626 403 GSC Bulletin 403. By R.L. Christie and N.J. McMillan.This bulletin contains a multidisciplinary study by several scientists, who have addressed the geological setting, the characteristics of the wood fossil and soils, as well as aspects of paleomagnetism, palynology, and paleobotany. The existence of mature forests so close to the North Pole in Tertiary time indicates the degree to which global climate has varied in the past, and is significant in our understanding of global change. This publication is a fine, solid foundation for future research. Black and white photographs. Résumés en français Softcover 91-17 1991-04-26 Fossils gcpds Geology gcpds Christie, R. L. McMillan, N.
