Surface uplift in world’s youngest orogen, can crustal thickening explain the uplift in Timor?

The island of Timor, SE Asia is the result of Arc-continent collision of the Banda Arc with the Australian Continental margin. Shortening of the Australian plate strata leads to thickening of the crust. Assuming isostasy, this should cause uplift. We hypothesize that the uplift of Timor can be explained by the built-up of a fold-and-thrust belt....
