About the Conference

The 31st Meeting of the Petrology Group of the Mineralogical Society of Poland - PTMin 2026 will be held under the theme “Rhyolite - Rock of the Year 2026”. This meeting embraces the idea of designating a “rock of the year” as an opportunity to highlight rhyolite - a rock of exceptional scientific and societal significance.

Rhyolite is fascinating from multiple perspectives: it is associated with climatically impactful eruptions, hosts important mineral resources, and preserves key records of magmatic processes involved in the evolution of continental crust. Moreover, rhyolitic supereruptions capture the imagination and provide a powerful gateway for public engagement with Earth sciences.

The conference aims not only to promote high-quality scientific exchange but also to strengthen outreach efforts through collaboration with the UNESCO Geopark of Extinct Volcanoes (The Kaczawskie Mountains and Foothills), bringing petrology closer to a broader audience.

This celebration of Rhyolite – Rock of the Year 2026 provides an opportunity to bring together scientists working on silicic rocks across Central Europe. We would like to invite all those particularly interested in this topic to the pre-conference Rhyolitic Group Meeting, dedicated to enhancing, establishing new, and strengthening existing cooperation in this field of research.

Traditionally, the main Petrology Group PTMin meeting will serve as a platform for mineralogists and petrologists to come together, exchange ideas, and foster collaboration during thematic and general sessions. The conference will also provide a unique opportunity to honor the contributions of Professor Jacek Puziewicz, founder of the Petrology Group. To celebrate his scientific legacy, a dedicated session on mantle evolution—his primary field of research—will be held.
