Three-dimensional lithospheric structure below the New Zealand Southern Alps
[1] Uppermost mantle seismic structure below the Southern Alps in South Island, New Zealand, is investigated by teleseismic P wave travel time residual inversion. The three-dimensional tomographic images show a near-vertical, high-velocity (2–4%) structure in the uppermost mantle that directly underlies thickened crust along the NNESSW axis of the Southern Alps. The center of the high-velocity ...
متن کاملNew zealand marine terraces: uplift rates.
WL iLLiAM B. BULL AND ALAN F. Cooper (1) identify as marine terrace remnants 18 "notches" or steps at altitudes up to 1700 m on the ridge crests southeast of the Alpine fault, New Zealand. They infer late Quatemary uplift rates on this upthrown side of the fault at three study areas. Their conclusions are based on (i) morphology ofthe steps, which are said to resemble eroded marine cliffs and s...
متن کاملRapid soil production and weathering in the Southern Alps, New Zealand.
Evaluating conflicting theories about the influence of mountains on carbon dioxide cycling and climate requires understanding weathering fluxes from tectonically uplifting landscapes. The lack of soil production and weathering rate measurements in Earth's most rapidly uplifting mountains has made it difficult to determine whether weathering rates increase or decline in response to rapid erosion...
متن کاملLichen Dating of Earthquake-generated Regional Rock- Fall Events, Southern Alps, New Zealand
Synchronous regional rockfall events triggered by large earthquakes in the Southern Alps of New Zealand were used to evaluate and improve the lichenometry method for surface-exposure dating. Digital calipers were used to measure the maximum diameter of the largest lichen on many rockfall blocks, using a fixed-area largest-lichen (FALL) sampling strategy. Regional significance of FALL peaks can ...
