Abstract

Accurate modelling, using seismic and gravity data, has shown that the Donnybrook Gravity High in central Queensland is the result of a complex situation involving three discordant basins. The most significant is an old basin buried deep beneath the Drummond Basin and apparently deposited in a valley carved out of a thick sequence of Silver Hills Volcanics and related acid volcanics. The Drummond Basin wedges out westwards under the Galilee Basin and is bounded to the east by the same acid volcanics that subcrop near the Anakie Metamorphics. The illusion that the Donnybrook Gravity High is associated with the Donnybrook Anticline is the result of an intrabasement granite which introduces a large negative component, cancelling the western flank of a much broader gravity high. After the cancellation, the granite is represented by a low of only 30 ~m.s-2 The already complex situation is further complicated by a topographic feature that introduces ambiguity in the most crucial area of the interpretation . This factor demonstrates the need to combine density profiling with forward modelling.
