The axial ranges of eastern North Island have grown in different processes of development north and south of the Hawke's Bay area in the Quaternary. The northern axial ranges had emerged by the early Pleistocene, when parts of the southern axial
ranges were still submerged. Back-arc spreading extended from the Havre Trough to central North Island c.1.8 Ma. Eruption of ignimbrite began in central North Island c.1.1 Ma., and migrated to the Taupo Volcanic Zone c.0.6 Ma. Interrupted by a period

Research initiated in 1909 by G. Leslie Adkin (1888–1964) suggested that the central Tararua Range on the North Island, New Zealand, was subjected to only limited alpine-style glaciation during the Late Pleistocene. This was based on the U-shaped
cross-profiles in the uppermost parts of several valleys, and cirque basins. Adkin’s work remained the only published glacial research undertaken on the North Island’s axial ranges until the latter part of the 20th century, but was not met with universal

The Holocene marine transgression in the region of the North Frisian Islands

The Holocene marine transgression in the region of the North Frisian Islands
To demonstrate the diverse Holocene developments in the region of the North Frisian Islands, the sedimentary sequences of the coastal Holocene in the areas of Sylt and Pellworm are compared. Local factors have to be considered in time and space

Size, shape and density sorting around two barrier islands along the north coast of Holland

Size, shape and density sorting around two barrier islands along the north coast of Holland
The sand movement on and around two barrier islands flanking the tidal flat area north of The Netherlands is studied by means of size, shape and density sorting. The coastline of the islands is still retreating. The removal of sand mainly occurs
. This process gives rise rive to a stepwise diminishing grain-size from island to island towards the east.
