Aeromagnetic legacy of early Paleozoic subduction along the Pacific margin of Gondwana Aeromagnetic legacy of early Paleozoic subduction along the Pacific margin of Gondwana
Comparison of the aeromagnetic signatures and geology of southeastern Australia and northern Victoria Land, Antarctica, with similar data from ancient subduction zones in California and Japan, provides a framework for reinterpretation of the plate tectonic setting of the Pacific margin of early Paleozoic Gondwana. In our model, the plutons in the Glenelg (south-eastern Australia) and...

Aeromagnetic map compilation: Procedures for merging and an example from Washington Aeromagnetic map compilation: Procedures for merging and an example from Washington
Rocks in Antarctica and offshore have widely diverse magnetic properties. Consequently, aeromagnetic data collected there can improve knowledge of the geologic, tectonic and geothermal characteristics of the region. Aeromagnetic data can map concealed structures such as faults, folds and dikes, ascertain basin thickness and locate buried volcanic, as well as some intrusive and...

Influence of subglacial geology on the onset of a West Antarctic ice stream from aerogeophysical observations Influence of subglacial geology on the onset of a West Antarctic ice stream from aerogeophysical observations
Marine ice-sheet collapse can contribute to rapid sea-level rise. Today, the West Antarctic Ice Sheet contains an amount of ice equivalent to approximately six metres of sea-level rise, but most of the ice is in the slowly moving interior reservoir. A relatively small fraction of the ice sheet comprises several rapidly flowing ice streams which drain the ice to the sea. The evolution of...

Aeromagnetic evidence for a volcanic caldera(?) complex beneath the divide of the West Antarctic Ice Sheet Aeromagnetic evidence for a volcanic caldera(?) complex beneath the divide of the West Antarctic Ice Sheet
A 1995–96 aeromagnetic survey over part of the Sinuous Ridge (SR) beneath the West Antarctic Ice Sheet (WAIS) divide shows a 70-km diameter circular pattern of 400–1200-nT anomalies suggesting one of the largest volcanic caldera(?) complexes on earth. Radar-ice-sounding (RIS) shows the northern part of this pattern overlies the SR, and extends south over the Bentley Subglacial Trench...

Seismic reflection images beneath Puget Sound, western Washington State: The Puget Lowland thrust sheet hypothesis Seismic reflection images beneath Puget Sound, western Washington State: The Puget Lowland thrust sheet hypothesis
Seismic reflection data show that the densely populated Puget Lowland of western Washington state is underlain by subhorizontal Paleogene and Neogene sedimentary rocks deformed by west and northwest trending faults and folds. From south to north beneath the Lowland, features seen on the seismic data include: the horizontally-stratified, 3.5 km thick Tacoma sedimentary basin; the Seattle...

Patterns of late Cenozoic volcanic and tectonic activity in the West Antarctic rift system revealed by aeromagnetic surveys Patterns of late Cenozoic volcanic and tectonic activity in the West Antarctic rift system revealed by aeromagnetic surveys
Aeromagnetic surveys, spaced ≤5 km, over widely separated areas of the largely ice- and sea-covered West Antarctic rift system, reveal similar patterns of 100- to 1700-nT, shallow-source magnetic anomalies interpreted as evidence of extensive late Cenozoic volcanism. We use the aeromagnetic data to extend the volcanic rift interpretation over West Antarctica starting with anomalies over...

Geodynamic Evolution of the Transantarctic Mountains and the West Antarctica Rift System: Proceedings of a workshop Geodynamic Evolution of the Transantarctic Mountains and the West Antarctica Rift System: Proceedings of a workshop
The workshop "Geodynamic Evolution of the Transantarctic Mountains and West Antarctic Rift System" was convened to provide a forum for discussion of future research on Antarctic rifting processes. The workshop drew on the expertise of thirty-one geologists and geophysicists currently involved in Antarctic research or investigating other rift systems. The general goal of the workshop was...
