Record #153280:

Gravity model studies of the volcanic island Surtsey, Iceland / THröstur THorsteinsson, Magnús T. Gudhmundsson.

Title: Gravity model studies of the volcanic island Surtsey, Iceland / THröstur THorsteinsson, Magnús T. Gudhmundsson.
Author(s): THorsteinsson, THröstur.
Gudhmundsson, Magnús T.
Date: 1999.
In: Jökull. (1999.), Vol. 47 (1999)
Abstract: Gravity data from 1992 was used to model internal structure of volcanic island formed in 1963-1967. Several models were made showing density variations. Best models have core of hyaloclastic tuffs from explosive stage, submarine delta of pillow lava breccias, subaerial lava and tephra and relatively dense sediments on northern peninsula. Intrusions are apparently too small to appear.
Notes:

Jökull. Vol. 47 :89-96 (1999).

Keywords: 550.8 -- Geology and geophysics, applied.
551.21 -- Volcanoes.
B -- Geology and soil sciences.
(*3) -- Arctic regions.
