This book demonstrates the direct link between petroleum, the derivative of organic materials, and ore bodies. The studies reported here highlight the common factors between hydrocarbons and mineral concentrations, such as heat sources, migration routes and likely traps. It emphasizes the role that hydrothermal processes play in the genesis of both petroleum generation and ore-grade mineralization. The presence of oil residue in the form of bitumen and pyrobitumen in all sediment-hosted ore bodies throughout the geological record is a testimony to their common diagenetic history. Studies of active hydrothermal systems reported in this book describe the processes and derivatives in these envi...

Finalist: Raymond Klibansky Book Prize Humanities and Social Sciences Federation of Canada (2008) Making a connection between photography and memory is almost automatic. Should it be? In Scissors, Paper, Stone Martha Langford explores the nature of memory and art. She challenges the conventional emphasis on the camera as a tool of perception by arguing that photographic works are products of the mind - picturing memory is, first and foremost, the expression of a mental process.

Scissors, Paper, Stone explores the great variety of photographic art produced by Canadian artists as expressions of memory. Their work, including images by Carl Beam, Carole Condé and Karl Beveridge, Donigan Cumming, Stan Denniston, Robert Houle, Robert Minden, Michael Snow, Diana Thorneycroft, Jeff Wall, and Jin-me Yoon, is presented as part of a rich interdisciplinary study of contemporary photography and how it has shaped modern memory.
