Abstract
Measurement of the rate of tectonically driven surface uplift is cruci al to a complete understanding of mountain building dynamics. The lack of a suitable rock record typically prevents determination of this qu antity, but the unusual geology of Papua New Guinea's Finisterre mount ains makes measurement of this rate possible. The tectonic surface upl ift rate at the Finisterre range is 0.8-2.1 mm yr(-1), approximately t hat expected to arise from crustal thickening.
