AbstractSedimentary structures and palyno-assemblages indicate that the sandstones of the lower part of the Hassel Formation of eastern Ellef Ringnes Island were deposited in an upper shore-face marine environment; sandstone, siltstone, shale and coal, comprising the middle and upper parts of the formation, have structures and features indicative of fluvial deposition. Thin, lenticular carbonaceous shale beds at Hoodoo Dome and Cape Cairo were analysed for their spore and pollen content. The microfloras indicate a late Albian and/or early Cenomanian age, which is consistent with regional paleontological and structural evidence. Humid, warm temperate conditions during Hassel deposition are suggested by the microflora.
