Acknowledgment

The financial background of our first Field Trip was estabilished by the Student Chapter Field Trip Grant dominated by the Committee of Student Chapters of the Society of Economic Geologists. We owe special thanks to the SEG for supporting our programs and activity at Eötvös Loránd University in the Carpatho-Panonian region. Our Academic sponsor is sincerely ackowledged for providing an excellent guide and understanding of the geology and mineral deposits of the Tokaji Mnts. The executive also thank the members for their contributions and chearful attendance.
