We had the pleasure to welcome Ph.D. Jakub Ciążela from Wrocław Univercity at 8th of December with his lecture about polimetalic sulfurs on the Atlantic Mid-Ocean Ridge and it’s exploration by Polish scientist. He also helped us to type useful pieces of rocks that was collected during our field work in Ślęża Massif. Ślęża Massif is remamnant of the ocean floor that had been uplifted and then exposed on the earth crust. The understanding how it happened and which proceses took place there will probably help in metalic sulfur exploration on the Atlantic Mid-Ocean Ridge.
