Tephrostratigraphy of the late Cenozoic Gold Hill loess, Fairbanks area, Alaska by Shari Jane Preece Download PDF EPUB FB2

Late Cenozoic loess blankets much of the Fairbanks region of interior Alaska, preserving a rich palaeoenvironmental record. Gold Hill Loess is the pre-Sangamon part of the loess cover in the Fairbanks area.

Twenty distinctive tephra beds have been characterized by stratigraphy, petrography, and glass major-/trace-element geochemistry. Preece, S. J.,Tephrostratigraphy of the late Cenozoic Gold Hill loess, Fairbanks area, Alaska: University of Toronto (Canada) M.S.

thesis, p. INTRODUCTION Tephra beds are common in Late Cenozoic loess deposits of interior Alaska. Recent work by Westgate et al. () documented a 3 Ma loess record in the Fairbanks area (Fig. The loess is interbedded with numerous thin and discontinuous tephra beds whose provenance is by: As a by‐product our data constrain the pelagic sedimentation rates in the eastern Pacific between 8°N and 10°N during that period of time.

In the companion paper (Part 2) we will discuss the implications for the Late Cenozoic explosive volcanism in southern Central America and the southern Central American continental by: Tephrostratigraphy of the late Cenozoic Gold Hill Loess, Fairbanks area, Alaska.

A more probable location of the top of the Gold Hill Loess than is shown in Fig. 2 (Péwé’s version) is discussed in this report. Tephrostratigraphy of the late Cenozoic Gold Hill Loess, Fairbanks Tephrostratigraphy of the late Cenozoic Gold Hill loess, Alaska.

() ().Located ∼47 km west of Fairbanks, this exposure was created during the construction of the George Parks Highway in the s, and is one of the most extensively studied loess sites in Alaska and the Yukon (e.g.

Westgate et al.,Westgate et al.,Begét. Gold Run tephra has been found at Thistle Creek, Sixtymile River, and the Klondike goldfields of west-central Yukon, Canada.

It is a hornblende-bearing rhyolitic tephra with thicknesses of up to 10 cm at each site, suggesting a widespread distribution across interior Alaska and the Yukon Territory, given the long distance to the nearest volcanic centre.

Many distal tephra beds exist in the late Cenozoic sediments of the Klondike goldfields and nearby areas. They come from volcanoes in the Wrangell volcanic field and the eastern Aleutian arc and represent large-magnitude eruptions.

Although the timing of an acceleration in late-Cenozoic exhumation of southern Alaska is reasonably well constrained as beginning ∼5–∼6 Ma, the surface uplift history of this region remains.

The so-called "muck", which is found near Fairbanks and other parts of Alaska is a favorite cliché piece of evidence for a terminal Pleistocene catastrophe for catastrophists like Collins (), Deloria (), Hapgood (), Allan and Delair () and Hawkins ().
