In June 1997, 78 scientists from 19 countries joined the symposium Tourmaline 1997 and presented more than 50 contributions in a broad range of tourmaline research – mineralogy, crystallography, petrology, synthesis, geochemistry, economic geology. A wealth of new data from a wide range of environments was presented: systematic crystal-structure studies, spectroscopic work of all forms, compositional studies of tourmaline from a number of different environments, and new synthesis and phase-equilibrium studies, etc. The symposium were followed by a three-day field trip to many tourmaline localities in the Czech Republic.

Here are few pictures from the conference (if you want to share your pictures from the symposium, we will be happy to add them here):

The symposium marked the start of rapid development in the tourmaline research in all its fields. Papers published in the conference issues of the European Journal of Mineralogy (2/1999, 3/1999, 4/1999) and Journal of the Czech Geological Society (1-2/1998) include:
