The Department of Geological and Atmospheric Sciences offers majors in three areas: Geology (traditional, environmental, or hydrogeology, for work as a surveyor or in mineral exploration), Meteorology (studies in global atmosphere, weather technology, and modeling for work as a meteorologist), and Earth Sciences (interdisciplinary mixture of geology, meteorology, and other natural sciences, with option of teacher-licensure).
History
The Department of Geology and Mining was founded in 1898. In 1902 its name changed to the Department of Geology. In 1965 its name changed to the Department of Earth Science. In 1977 its name changed to the Department of Earth Sciences. In 1989 its name changed to the Department of Geological and Atmospheric Sciences.

Abstract
Gold deposits in Greece are spatially associated with back-arc/arc related volcanic, subvolcanic and plutonic rocks, which were controlled by extensional kinematic conditions when metamorphic core complexes in the Rhodope-Serbomacedonian- and Attico-Cycladic Massifs were uplifted to near surface levels over the south-westward retreating Hellenic subduction zone. Porphyry Cu-Mo-Au, high-intermediate sulfidation epithermal Au-Ag deposits and other intrusion-related proximal to distal systems (skarn, carbonate replacement, metamorphic rock-hosted quartz veins) are characterized by enrichment of trace metallic minerals like bismuth sulfosalts and Bi-sulfotellurides, precious- and base metal tellurides and Se-bearing phases, which can be considered as pathfinder minerals for gold as they are intimately associated with gold-bearing ores. Mineralogical studies of various styles of gold deposits in Greece can be applied as an exploration tool and selected examples from well described mineralization/deposits are presented here.
