Strontium isotope ratios in volcanic rocks from the south-eastern part of the Hellenic arc
Lithos, 1975Abstract Isotopic ratios of strontium in 9 volcanic rocks from the south-eastern part of the Hellenic arc range from 0.7037 to 0.7075. Within individual series of differentiation, there seems to be a correlation between Sr 87 /Sr 86 and K 2 O/SiO 2 . All strontium isotope data for the Hellenic arc are reviewed.

Abstract Gas seeps were located, by echo sounding, SCUBA divers and ROV observations, at hydrothermal sites around the island of Milos, in the Hellenic Volcanic Arc. Samples were collected by SCUBA divers and by a ROV from water depths between 3 and 110 m.

The geochemical study of 5 sediment cores obtained from different shallow hydrothermal fields along the volcanic arc (Methana, Milos, Kos and Yali), revealed that the degree of rock hydrothermal alteration from one area to another is different and is influenced by the physical and geochemical properties of the hydrothermal venting fluids and the type ...

A first insight of Hg occurrence in the hellenic volcanic arc
Global NEST International Conference on Environmental Science & Technology, 2023Mercury is a highly toxic element with both natural and anthropogenic sources to the marine environment, with implications to ecosystems and human health. It is recognized as a priority pollutant by the European Environmental Legislation and the United Nations Environmental Program (UNEP).

Hydrothermal sedimentation in the caldera of Santorini, Hellenic Volcanic Arc
Terra Nova, 1995ABSTRACTSediments in the caldera of Santorini are receiving a hydrothermal input of iron and manganese from presently active hydrothermal vents off the Kameni Islands, and are enriched in these elements in their surface layer. However, greater Fe‐Mn enrichments occur in discrete layers at depth in the cores separated from the surface by Fe‐Mn poor ...

Suspended particulate matter (SPM) separated from waters discharging from a number of submarine hydrothermal vents at Palaeochori bay, Milos island was analysed for major and trace elements (i.e. Fe, Mn, Cu, Pb, Cd, Ca, Sr, Si, Al, Ba).

Geochemistry of hydrothermally influenced sediments off Methana (western Hellenic volcanic arc)
Geochemistry, 2004Abstract Surface sediment samples from near-shore shallow water as well as deeper water locations N and NE of the island of Methana were investigated geochemically. Shallow water samples from Thiafi Bay reveal up to 38-fold enrichment of As, associated with elevated contents of Sb, Fe and Zn.

Plio-Pleistocene age of high-potassium volcanism in the northwestern part of the hellenic arc
TMPM Tschermaks Mineralogische und Petrographische Mitteilungen, 1979Two newK/Ar dates firmly establish that the high potassium volcanic rocks of Thessaly are of late Pliocene and Pleistocene age, considerably younger than the geochemically similar rocks of the Dodecanese.

In this study SAR interferometry technique has been applied over Kos Island (Hellenic Volcanic Arc) in order to detected pre-, coand post-seismic deformation and to compare with the deformation detected in Nisyros Island for the same period using the same interferometric pairs.
