Iceland Can Be Considered Volcanologist “Heaven”
Iceland can be considered volcanologist “heaven” 1) Sub-aerial continuation of the Mid-Atlantic Ridge 2) Intersection of a mantle plume with a spreading ocean ridge 3) Volcanism associated with tectonic rifting 4) Sub-glacial volcanism 5) Tertiary flood (plateau) basalts 6) Bi-modal volcanism 7) Submarine volcanism 8) 18 historically active volcanoes 9) Eruptions roughly every 5 years 1. The North Atlantic opened about 54 Ma separating Greenland from Europe. 2. Spreading was initially along the now extinct Agir ridge (AER). 3. The Icelandic plume was under Greenland at that time. 4. The Greenland – Faeroe ridge represents the plume track during the history of the NE Atlantic. Kolbeinsey ridge (KR) 5. During the last 20 Ma the Reykjanes Ridge (RR) Icelandic rift zones have migrated eastward, stepwise, maintaining their position near the plume 6. The plume center is thought to be beneath Vatnajökull 1 North Rift Zone – currently active East Rift Zone – currently active West Rift Zone – last erupted about 1000-1300 AD [Also eastern (Oræfajökull) and western (Snæfellsnese) flank zones] Rift zones comprise en-echelon basaltic fissure swarms 5-15 km wide and up to 200 km long. Over time these fissures swarms develop a volcanic center, eventually maturing into a central volcano with a caldera and silicic Tertiary volcanics > 3.1 Ma volcanism Late Tertiary to Early Quaternary 3.1 – 0.7 Ma Neo-volcanic zone <0.7 - present Schematic representation of Iceland’s mantle plume. The crust is about 35 – 40 km thick Iceland’s mantle plume has been tomographically imaged down to 400 km. Some claim even deeper, through the transition zone, and down to the core – mantle boundary. -

Your Cruise Icelandic Nature and Traditions
Icelandic nature and traditions From 8/11/2021 From Reykjavík Ship: LE DUMONT-D'URVILLE to 8/22/2021 to Reykjavík Discover the most beautiful landscapes on the Icelandic west coast during an 12-day PONANT cruise. On the edge of the Arctic, between vast glaciers, vertiginous fjords, volcanoes and boiling geysers, thiscircumnavigation will enable you to discover the wild and romantic landscapes of Iceland. Departing from Reykjavík, you will set off aboardLe Dumont-d’Urville, heading for Heimaey, the only inhabited island in the Westman archipelago. It is an exceptional place composed of volcanoes and almost- desert landscapes, where fishing is the main food source. You will then set sail for the bay ofGrundarfjörður , right near Kirkjufell. This stunning cone-shaped mountain possesses a unique charm and this will be an opportunity to take some beautiful photos. After visiting the villages ofÍsafjörður and Djúpavík, you will head for Siglurfjörður, to the north of Tröllaskagithe peninsula, whose mountainous silhouettes are reminiscent of French alpine reliefs. Founded in the 10th century, this small port reputed for herring fishing is also known for the beauty of its fjord. Le Dumont-d’Urville will sail for Grímsey, a small, hard-to-reach island where, in certain places, the volcanic rock forms magnificent basalt columns. Sea birds reign here. Akureyri, the capital of north Iceland, will welcome you on the shores of the Eyafjörður fjord, very close to the Arctic Circle. Your ship will then head south again toHornafjörður , in the Vatnajökull National Park, a UNESCO World Heritage Site. You will be dazzled by the beauty of the landscapes around the Jökulsarlon glacial lake. -

The dataset on which the report is based has been collected from the National Well Registry of boreholes and available reports. To the extent verifiable data are available, the assembled dataset is presented in an Excel document accompanying the report on CD. About 93% of the drilled wells were productive, i.e. encountered feeders that could yield a flow from the well. -
Signature of Deep Mantle Melting in South Iceland Olivine
Contributions to Mineralogy and Petrology (2019) 174:43 https://doi.org/10.1007/s00410-019-1580-8 ORIGINAL PAPER Signature of deep mantle melting in South Iceland olivine Paavo Nikkola1,2 · Guðmundur H. Guðfnnsson2 · Enikő Bali2,3 · O. Tapani Rämö1 · Tobias Fusswinkel4 · Thorvaldur Thordarson2,3 Received: 1 December 2018 / Accepted: 26 April 2019 / Published online: 13 May 2019 © The Author(s) 2019 Abstract We present new high-precision major and trace element data on olivine macrocrysts from various volcano-tectonic settings in Iceland and use these data as a proxy for mantle mode and melting conditions. Within individual sampling sites examined (seven lavas and one tephra) olivine-dominated fractional crystallization, magma mixing and difusive re-equilibration control observed variability in olivine composition. High-pressure fractional crystallization of clinopyroxene may have lowered Ca and increased Fe/Mn in one olivine population and subsolidus difusion of Ni and Fe–Mg afected the mantle-derived Ni/Fo ratio in some compositionally zoned olivine macrocrysts. Interestingly, magmas erupted at the southern tip of the Eastern Volcanic Zone (SEVZ), South Iceland, have olivines with elevated Ni and low Mn and Ca contents compared to olivines from elsewhere in Iceland, and some of the SEVZ olivines have relatively low Sc and V and high Cr, Ti, Zn, Cu and Li in comparison to depleted Iceland rift tholeiite. In these olivines, the high Ni and low Mn indicate relatively deep melting (Pfnal > 1.4 GPa, ~ 45 km), Sc, Ti and V are compatible with low-degree melts of lherzolite mantle, and elevated Zn may suggest modal (low-olivine) or geochemical (high Zn) enrichment in the source. -

The threat of aquatic invasive species in particular can be difficult to detect, and climate change may facilitate the spread and establishment of new species. In 2003, the European brown shrimp Crangon crangon L. was discovered off the southwest coast of Iceland. This species is a concern for Iceland due to the combination of its dominance in coastal communities and level of predation on juvenile flatfish, namely plaice Pleuronectes platessa L., observed in its native range. -

Westfjords Way) by the opening of a tunnel between Arnarfjörður and Dýrafjörður, an important link between the north and south parts of the Westfjords. The opening of the Dýrafjörður Tunnel ensures the new Westfjords Way will be open year-round by relieving the Hrafnseyrarheiði mountain pass that is unpaved and closed for long periods of the year. Vestfjarðaleiðin is however more than just a scenic route as it is also a way of life in the Westfjords and Dalabyggð, the part that looks a little bit like a head on Iceland’s body. The Westfjords have in this way always stood proud from the rest of Iceland, physically and culturally. The Westfjords peninsula is older than Iceland’s body, dramatically marked by the Ice age 10 thousand years ago with deep fjords that provide a unique driving route adorned with cliffs, craggy mountains, valleys, lowlands and unique flora and fauna. -
Itinerary - South Coast Adventure - 7 Days
Itinerary - South Coast Adventure - 7 Days DAY 1: REYKJAVÍK AND THE GOLDEN CIRCLE Get ready for a busy day! Today, you will see some of the most popular tourist attractions in the whole of Iceland. Leave Reykjavík and visit Gljúfrasteinn, the home of the most famous Icelandic novelist and Nobel- prize winner, Halldór Laxness, before reaching Þingvellir National Park. The park is not only home to the most important place in Icelandic history, where one of the world's oldest parliaments was founded in 930, but also Iceland's largest natural lake and a lava field, situated right on the Mid-Atlantic Ridge, where the Eurasian and 1 North American tectonic plates are moving apart. At Þingvellir you can walk through parts of the ridge. Carry on through the town of Laugarvatn, with a pretty lake baring the same name. Next up, it's the hot spring area of Geysir, including the very active geyser Strokkur, erupting every 5 to 10 minutes. Spend time walking along the paths and looking at the different geothermal phenomena. Carry on to the beautiful Gullfoss waterfall or the "Golden Waterfall". 32 m high and 250 m wide, the water falls into a 70 m deep gorge, allowing for breathtaking views from different viewpoints. Finish the day with a visit to Skálholt church and archaeological remains, one of Iceland’s places of special historical interest. DAY 2: THE ÞJÓRSÁRDALUR VALLEY, HYDROPOWER, AND VIKING SETTLERS Iceland is known for its hydroelectric power, and today you get a chance to check out one of the country's impressive power plant stations in the river Þjórsá, which has a visitor centre open during the summer months. -
