CONTRIBUTION TO THE FLORA OF THE SOUTH AEGEAN Volcanic Arc: KIMOLOS ISLAND (KIKLADES, GREECE)
Edinburgh Journal of Botany, 2014Co-Authors: K. Kougioumoutzis, A. Tiniakou, O. Georgiou, T. GeorgiadisAbstract:The island of Kimolos, located in the western Kiklades in Greece, constitutes together with Milos, Polyaegos, Anafi and the Santorini island group the central part of the South Aegean Volcanic Arc. The flora of Kimolos consists of 443 taxa, 70 of which are under a statute of protection, 30 are Greek endemics and 225 are reported here for the first time. We show that Kimolos has the highest percentage of Greek endemics in the South Aegean Volcanic Arc. The known distribution of the endemics Sedum eriocarpum subsp. eriocarpum and Anthemis rigida subsp. liguliflora is expanded, being reported for the first time for the phytogeographical region of the Kiklades. The floristic cross-correlation between Kimolos and other parts of the South Aegean Volcanic Arc by means of Sørensen’s index revealed that its phytogeographical affinities are somewhat stronger to Anafi than to neighbouring Milos.

Palaeoproterozoic mineralized Volcanic Arc systems and tectonic evolution of the Fennoscandian Shield: Skellefte District Sweden
GFF, 2010Co-Authors: Pär WeihedAbstract:The Skellefte 1.9 Ga Volcanic Arc in northern Sweden is one of the most mineralized (VMS, orogenic gold, mafic hosted Ni, porhyry style Cu-Au) Palaeoproterozoic Arc systems in the world. The Skellefte District is interpreted to have accreted, or formed as a continental Volcanic Arc system, during accretionary processes related to the Svecokarelian Orogeny. Based on Sm-Nd isotope studies it has been concluded that the basement to the ore-bearing Skellefte Group cannot be much older than the Volcanic Arc and was thus probably juvenile Palaeoproterozoic crust. The basement is not known to outcrop and recently it was speculated, based on high resolution seismic work in the western part of the district, that the basement is dipping gently northwards beneath the ore-bearing Skellefte Group. It was further postulated from these studies that the basement could at least partly constitute the Bothnian supergroup, metasedimentary rocks that outcrop south of the Skellefte District. Part of this supergroup has been da...

Emplacement and deformation of granitoids during Volcanic Arc construction in the Foothills terrane, central Sierra Nevada, California
Tectonophysics, 1991Co-Authors: Scott R. Paterson, Othmar T Tobisch, Ron H. VernonAbstract:Abstract Emplacement of a series of late Jurassic to early Cretaceous tonalites and diorites at depths of 4 to 9 km accompanied Volcanic Arc construction in the Foothills terrane, central Sierra Nevada, California. Emplacement of these plutons occurred after initiation of faulting and rigid-rotation of bedding and immediately before widespread cleavage development. Pluton emplacement occurred by permissive emplacement in the hinges of large anticlines or domes, or as structurally controlled sill-like bodies in a ductile shear zone and was accompanied by widespread mingling of magmas. Subsequent deformation rotated but did not internally deform one pluton, strongly deformed several others and shortened the overlying Volcanic and sedimentary sequences by 30 to 50%. We suggest that deformation was active throughout Volcanic Arc construction, but evolved from early more “brittle” deformation to ductile flow immediately after pluton emplacement and back to brittle deformation as the Arc was uplifted and cooled. At this location, Arc magmatism lasted at least 30 Ma whereas deformation lasted at least 35 Ma and possibly much longer. The different emplacement mechanisms, changing style of deformation and differences in viscosity contrast between plutons and wall rocks resulted in an impressive variety of structural characteristics and apparent timing relationships for the subVolcanic plutons.

Volcanic evolution of the South Sandwich Volcanic Arc, South Atlantic, from multibeam bathymetry
Journal of Volcanology and Geothermal Research, 2013Co-Authors: Philip T. Leat, Alex J. Tate, Tara J. Martin, Simon Day, Matthew J. Owen, David R. TappinAbstract:Abstract New multibeam bathymetry data are presented for the South Sandwich intra-oceanic Arc which occupies the small Sandwich plate in the South Atlantic, and is widely considered to be a simple end-member in the range of intra-oceanic Arc types. The images show for the first time the distribution of submarine Volcanic, tectonic and erosional–depositional features along the whole length of the 540 km long Volcanic Arc, allowing systematic investigation of along-Arc variations. The data confirm that the Volcanic Arc has a simple structure composed of large volcanoes which form a well-defined Volcanic front, but with three parallel cross-cutting seamount chains extending 38–60 km from near the Volcanic front into the rear-Arc. There is no evidence for intra-Arc rifting or extinct Volcanic lines. Topographic evidence for faulting is generally absent, except near the northern and southern plate boundaries. Most of the Volcanic Arc appears to be built on ocean crust formed at the associated back-Arc spreading centre, as previously proposed from magnetic data, but the southern part of the Arc appears to be underlain by older Arc or continental crust whose west-facing rifted margin facing the back-Arc basin is defined by the new bathymetry. The new survey shows nine main Volcanic edifices along the Volcanic front and ca. 20 main seamounts. The main volcanoes form largely glaciated islands with summits 3.0–3.5 km above base levels which are 2500–3000 m deep in the north and shallower at 2000–2500 m deep in the south. Some of the component seamounts are interpreted to have been active since the last glacial maximum, and so are approximately contemporaneous with the Volcanic front volcanism. Seven calderas, all either submarine or ice-filled, have been identified: Adventure volcano, a newly discovered submarine Volcanic front caldera volcano is described for the first time. All but one of the calderas are situated on summits of large volcanoes in the southern part of the Arc, and most are associated with current or historic Volcanic or hydrothermal activity. Shallow shelves around the islands are generally 1–10 km wide. Submerged banks up to 1100 m deep are interpreted as subsided erosional surfaces. Seamounts and emergent volcanoes experienced a range of mass wasting processes including by landsliding and smaller mass flows.
