Defects and Processes in the Solid State: Geoscience Applications

About this book

This work, in honour of Alexander Clark McLaren on the occasion of his 65th birthday and retirement, has as its central theme the role of defect structures in the processes of deformation, phase transformations and microstructural development in rocks and minerals. These topics also span the major scientific interests that have exercised the mind and research activities of Alexander Clark McLaren since 1953.
