Fluids in the Crust

Will be of great interest to all geoscientists interested in hydrothermal processes and experimental geochemistry ... Its publication is a welcome step forward in the process of forging links between the two populations of scientists working in the old Soviet Union and the West, and publicizing the excellent contributions to geochemistry made by the Chernogolovka community - Geological Magazine; ...a treasure house of data and methods on hydrothermal systems. - Geoscientist.; ...a valuable and comprehensive review of the detailed experimental work on crustal fluids and their interaction with rocks and minerals undertaken over the past decade in the former Soviet Union...the editors have ensured that the English is clear and that the figures are of high quality...Such a wealth of new experimental data is extremely useful and will expand significantly the database available in the west... - The Times Educational Suppliement
