This conference followed the successful conference on the "South Aegean Active Volcanic Arc" in 2003, under the framework of the Milos Conferences - Magmatism in Convergent Margins. The conference was held at the Milos Conference Centre - George Eliopoulos: this well-equipped facility provides a superb environment for scientific discussions of the type you would expect at a Penrose or Goldschmidt conference.
The conference was a Milos Conferences event.
Neogene magmatism in the central Aegean took place in a rapidly extending, continental back-arc environment. It includes shoshonites of the northeast Aegean islands and adjacent Anatolia, mid-crustal plutons of the Cyclades, and a wide variety of minor volcanic centres that range in composition from alkali basalt to adakite to trachyte to rhyolite. An equally wide range of mineral deposits types are associated with this magmatism. The petrogenesis of these varied rock types is still hotly debated and the reasons why particular rocks formed at particular times and in particular places are not well understood.
The answers to these questions will come from the integration of many disciplines. Modern geochemical, isotopic and petrographic studies are needed for many of the magmatic rocks. The biostratigraphic position of some volcanic rocks and the geochronology of many plutonic rocks remains poorly known. Volcanic rocks show strong temporal and spatial correlation with faults, but the pattern of active faults in the back-arc region has changed profoundly from the Miocene to the Quaternary. The detailed relationship of plutonism and mineralisation to regional extension is poorly understood. How do the differences between magmatism in the Aegean and in western Anatolia result from differences in crustal thickness and history of extension? How can findings from seismic tomography help an understanding of Neogene magmatism? What do paleomagnetic studies reveal about the paleogeography at the time of older magmatism? How does mineralisation relate to changing patterns of tectonism and magmatism?
We invited oral or poster contributions that were of relevance to understanding of Neogene magmatism, in fields that include igneous petrology and geochemistry, mineral deposits and economic geology, stratigraphic studies, geochronology, metamorphic petrology, structural geology, and paleomagnetism. The scope of the conference was not limited to the Neogene: studies of older rocks that throw light on the origin of Neogene magmatism in the central Aegean and adjacent areas were included. The conference also considered the environmental implications of Neogene magmatism and mineralisation.
