Australia's lithospheric density field, and its isostatic equilibration

A.R.A. Aitken, C. Altinay and L. Gross.

in Geophysical Journal International

P ublished online November 2015 .

Journal Article. Subjects: Geodesy and Surveying for Maps and Charts. 11698 words.

Density is a key driver of tectonic processes, but it is a difficult property to define well in the lithosphere because the gravity method is non-unique, and because converting to density...
