Patterns of Late Cenozoic exhumation deduced from apatite and zircon U-He ages from Fiordland, New Zealand

[1] New apatite and zircon (U-Th)/He ages from the Fiordland region of New Zealand’s South Island expand on earlier results and provide new constraints on patterns of Late Cenozoic exhumation and cooling across this region. Zircon (U-Th)/He cooling ages, in combination with increased density of apatite ages, show that in addition to a gradual northward decrease in cooling ages that was seen dur...

Physical Influences on Forest Types and Deer Habitat, Northern Fiordland, New Zealand

Forest types of the Wapiti, Doon and Glaisnock catchments, ranked in order of proportion of preferred food species for deer, paralleled a gradient of landform stability. Seral forests and low altitude silver beech forests were preferred deer habitat because they contained the largest proportions of highly preferred species. They often occurred on unstable landforms such as debris cones, colluvi...

Mark, Rawson and Wilson: Vegetation Pattern of a Fiordland Raised Mire Vegetation Pattern of a Lowland Raised in Eastern Fiordland, New Zealand

The vegetation pattern of Borland Mire, a 250 ha lowland raised mire near Monowai, in the rainshadow of the Fiordland mountains, is described using several numerical analyses of quadrat data collected at regular intervals along parallel transects across 430 m of a typical segment. A weak zonation pattern of both flora and vegetation is revealed amolng the 24 vascular species and the more abunda...

provenance of zaygun formation, based on petrography, modal analysis and geochemistry in sarbandan section, central alborz

petrography, modal analysis of sandstones and major elements geochemistry of shales of early cambrian zagun formation in sarbandan section, central alborz, are used to identify their provenance (including parent rocks, tectonic setting and paleo-weathering). petrography of the sandstones and plotting their point counting data on qt44, f47, l9 and qm44, f45 ,lt11 diagrams imply that they are ark...

Forest Understorey Changes after Reduction in Deer Numbers, Northern Fiordland, New Zealand

High deer numbers in northern Fiordland in the 1960s significantly changed forest understorey composition. The density of woody plants in the understorey was reduced in some areas by as much as 50%, and preferred plants became less abundant than those seldom eaten. However, the impact of deer and wapiti varied between forest types. Seral communities and silver beech forests at low altitudes in ...
