ISA 2020-22
43rd International Symposium on Archaeometry 
Postponed to May 16-20, 2022   

Dear colleagues 

All of us love attending conferences. Attending a conference was never about just listening to talks - it was about meeting people, networking, making friends, learning new things, and understanding different cultures.
Conference organizers caught in the current health crisis should make rational decisions about their conferences.
The COVID-19 pandemic that so deeply affects our lives and countries is not expected to end soon, and its consequences will be felt for a long time. In particular, satisfactory conditions for international scientific conferences to take place will certainly not be fulfilled in the next months.
We have made the decision to further postpone the ISA 2020.
We are thus forced to postpone the 43rd Symposium on Archaeometry of May 2020 and to settle a new date, in order to create an experience that is safe and rewarding for all involved.

After much deliberation and conversation, the following actions have been decided by Local Organizing Committee together with the International Standing Committee:
Due to the currently uncertain lifetime of the current COVID-19 crisis, the Lisbon 43rd ISA will be postponed for 2 years from its original date, and is rescheduled for May 16-20, 2022 – again in Lisbon, and in the same venues (and with the same Local Organizing Committee). The Congress program, which had already been finalized, will remain the same for 2022 (assuming the willingness of currently enlisted speakers to participate and upon confirmation of authors). The congress web site will remain live until the 2022 congress and updated accordingly. This was no easy decision but was a necessary one, and the only appropriate option, given the enormous material and immaterial compromise already assumed by the local organization. We sincerely apologize for any inconvenience this will cause for you. We trust that you understand that we made this decision in the best interests of all ISA community. We wish to assure you that your agreements, registration and participation is unchanged valid for the new dates. We look very much forward to welcome you in Lisbon 2022.  

Best wishes to you all at this truly astonishing and challenging time. Resilience-based approaches and research have never been more critical.
Above all, stay safe, healthy and updated

M. Isabel Dias, Chair of the Organization

Symposium Program

Loyal to the initial scientific program, the 43rd Symposium on Archaeometry to be held in 2022 will be built under the same sessions. Some changes will be indeed introduced since nothing remains the same after the enormous test, we are all being submitted. For the time being, we are still working on a stimulating scientific program, that will develop around the previously selected works.
Nevertheless, we are aware that some of the previously sent works might be out of date. So, all previously submitted contributions will not be processed without notice to the ISA 2020-2022 program. An opportunity for updating your contributions will be announced in due time. We will keep your pre-registration in our files so that we may send you further information in due time. If you do not agree, please let us know (by a simple e-mail to and we will delete your full record). Still, we hope to see you all in Lisbon in 2022, for celebrating the continuation of this regular series of ISA Symposiums.
