Edited by G. D. Veiga, L. A. Spalletti, J. A. Howell and E. Schwarz

The Neuqu~n Basin of northern provides an excellent case study in basin analysis and sequence stratigraphy. The basin is one of the largest petroleum provinces in and includes a dramatic record of relative sea-level changes as well as a unique and globally important palaeontological record. Understanding this region is also central to unravelling the history of the Andes. The latest developments in the study of the area have been combined in this volume to give an integrated series of case studies that document the structural, igneous, sedimentological and palaeontological history of the region from the Triassic to the Recent. This publication provides an introduction into this fascinating region as well as a resource that includes the most complete and up-to-date studies of the area.
