Record #97601:

Radar imaging of glaciovolcanic stratigraphy, Mount Wrangell caldera, Alaska: interpretation model and results / Garry K.C. Clarke, Guy Matthew Cross, Carl S. Benson.

Title: Radar imaging of glaciovolcanic stratigraphy, Mount Wrangell caldera, Alaska: interpretation model and results / Garry K.C. Clarke, Guy Matthew Cross, Carl S. Benson.
Author(s): Clarke, Garry K. C.
Cross, Guy Matthew.
Benson, Carl S.
Date: 1989.
In: Journal of Geophysical Research. (1989.), Vol. 94(B6) (1989)
Abstract: Model developed that allows depth variation of temperature, heat flux, pressure, density, ice velocity, depositional age, and thermal and dielectric properties to be calculated. By using model to calculate two-way travel time and propagation losses, radar sounding traces can be transformed to give estimates of variation of power reflection coefficient as function of depth and depositional age. Prominent internal reflecting zones are located; these are attributed to buried horizons of acidic ice, possibly intermixed with volcanic ash, that were deposited during past eruptions. Depositional dates corresponding to these reflecting zones are 1728, 1770, 1853, and 1924-1950 AD. This information is used to propose volcanic history for Mount Wrangell.
