Concluding note

 

We would like to thank all the participants for making the first LASI workshop such a success. Without all your valuable contributions we would not have been able to organize and fund this meeting in Freiberg.

Publication

We aim to publish selected papers in a special issue of the Journal of the Geological Society, London. Manuscripts should be handed to the editors at the meeting. Exceptionally, a prolonged deadline (15th Nov 2002) will be accepted for those who want to incorporate results of discussions during the meeting.

 

Instructions for authors at this link!

Please remember the deadline!
