Papers presented at the first international Tasman Sea Conference cover a wide variety of geoscience topics, both in subject matter and geologic time interval, ranging from the break-up of Gondwana to Quaternary oxygen isotope and paleoclimate data, from hotspot trails to atmospheric and oceanic circulation, from Cretaceous granites to ostracod dissolution. The papers are not assigned to specific categories, but are arranged in a logical order, covering the mid-Cretaceous onset of the opening of the Tasman Sea to Quaternary oceanographic events.

Providing an assessment of the state of knowledge on the Tasman Sea Basin, this text covers an up-to-the-minute assessment of the state of knowledge on the Tasman Sea Basin. The papers deal with the geological & geophysical aspects of Gondawa break-up (opening of the Tasman Sea), including hot-spot-trails, granite emplacement, paleomagnetism & rifted-marginal basins; Paleooceanography, including atmospheric & oceanic circulation patterns; Detailed examinations of oxygen-isotope records, distribution patterns & dissolution records of marine fauna, providing new paleoclimatic & paleogeographic information relating to geologically most recent evolutionary history of Tasman Sea Basin.
