Product description:Reviewer's Note The Palaeozoic and late Precambrian history of the interactions between the ancient Pacific Ocean and the Gondwana supercontinent are partly shown by the geology of the Tasman Fold Belt System in eastern Australia. A continuing theme of these interactions has been cratonic/orogenic detrital input into a convergent margin setting resulting in the development of several major orogenic belts. In southeastern Australia these orogenic belts (subsets of the Tasman Fold Belt System) include the Delamerian Fold Belt of South Australia, western Victoria and western New South Wales and the Lachlan Fold Belt of Victoria, New South Wales and Tasmania. This volume is concerned with an updated account of the geology and mineralisation of the Delamerian and Lachlan fold belts in Victoria with important inferences for the extensions of these belts into other states of Australia and also for dispersed fragments of Gondwana. Among the more interesting issues canvassed is the fate of the Late Precambrian and Cambrian passive margin of Gondwana. This margin, which is more widely exposed in South Australia, was subjected to intense deformation, metamorphism and plutonism as a result of the Delamerian Orogeny when the Gondwana passive margin was converted to a new orogenic belt. Another highlight is a definitive account of the western boundary of the Lachlan Fold Belt with descriptions and interpretations of the Moyston Fault and the Grampians Allochthon. The main topic of this volume, however, is a detailed description of the complex set of what many regard as exceedingly cryptic events that heralded the formation of the Lachlan Fold Belt in the Middle Cambrian to Carboniferous. This part of the book illustrates how the Lachlan Fold Belt formed by the deformation of oceanic rocks as well as the incorporation of a northern extension of Tasmania ("Selwyn Block"). This represents a compromise of sorts to the long-standing debate between those who supported either an oceanic or a continental basement to the Lachlan Fold Belt. Who should read this volume? Needless to say anyone with interests in the geology of Victoria will find this volume an essential and well-used addition to their bookshelf. Those with interest in the geology of adjoining states (South Australia, New South Wales and Tasmania) will also find this volume essential reading. The apparent complexity and enormity of the literature has discouraged geologists interested in the Palaeozoic history of the Pacific Ocean from tackling an understanding of southeastern Australia. At last these people will find in this volume a safe haven for establishing the factual basis and interpretation of what the Delamerian and Lachlan fold belts mean for the ancient Pacific Ocean and Gondwana. The book will also be a reliable geological guide for lay people interested in the new developments in the geology of Victoria. I congratulate the members of the Geological Survey of Victoria for the production of this excellent book and commend it to all.
