Gagnasafn (GDB) NI_J600v_berg_2.utg: Jarðfræðikorti af Íslandi – Berggrunnur – 1:600.000 [Geological Map of Iceland – Bedrock geology – 1:600.000]. Berggrunnskort af Íslandi sýnir stærstu drættina í jarðfræði landsins. Jarðlög eru flokkuð eftir aldri, gerð og samsetningu. Kortið sýnir vel gosbelti landsins og dreifingu gossstöðva frá nútíma. Nútímahraunum er skipt í forsöguleg og söguleg hraun (yngri en 871 e. Kr. ). [The Geological Map of Iceland shows the main features of the bedrock geology. Formation are classified by age, type, and composition. The map clearly shows the island's volcanic zones and the distribution of the recent eruption sites. Lava fields of the Holocene are shown as pre-historic or historic (younger than AD 871].]

Gagnasafn (GDB) NI_J600v_hoggun: Jarðfræðikorti af Íslandi – Höggun – 1:600.000 [Geological Map of Iceland – Tectonics – 1:600.000]. Höggunarkort af Íslandi sýnir jarðfræði landsins á nýstárlegan hátt. Jarðlög eru flokkuð eftir aldri en ekki eftir gerð og samsetningu. Sýnd eru eldstöðvakerfi, þ.e. megineldstöðvar, sprungu- og gangareinar, bæði virkar og útkulnaðar. Einnig eru sýnd helstu brotakerfi landsins og halli jarðlaga. Kortið gefur innsýn í jarðfræðilega byggingu landsins. [The Tectonic Map of Iceland gives a new view of the country's geology. The rocks are classified by age, but not by type or composition. Volcanic systems including central volcanoes, fissures and dyke swarms, both active and extinct, are shown, as are the island's principal fracture zones and the dip of rock layers. The map thus gives a useful insight into the geological structure of the country.]

Þekja [layer] j100v_vesturgosbelti_gigar_1utg_li: Gígar á Vesturgosbelti, línulag. [Craters of the Western Volcanic Zone, line data.] Gögn sem sýna gígaröð og útlínur. Gerður er greinarmunur á gossprungum, Holósen útlínur gíga (yngri og eldri en 7000 ára) og gígar frá Kvarter (kuldaskeið/hlýskeiðs). [Data detailing crater rows and outlines. This includes distinctions between eruptive fissure rows, Holocene crater outlines (younger and older than 7000 years), and quarternary (glacial/interglacial) craters.]

The map displays bedrock formations at or near the surface of the land, on the sea floor above the continental crust that forms the Canadian landmass, and oceanic crust surrounding the landmass. The bedrock units are grouped and coloured according to geological age and composition. The colours of offshore units and oceanic crust are paler and more generalized than those on land, although the constituent units offshore are still easily discernible from their dashed boundaries. This colour design, coupled with the use of a white buffer zone at the coast allows the coastline of Canada to be readily distinguished and still show the grand geological architecture of the Canadian landmass. The map also shows major faults that have disrupted the Earth's crust, onshore and offshore, and a variety of special geological features such as kimberlite pipes, which locally contain diamonds, impact structures suspected to have been caused by meteorites, and extinct and active spreading centres in the surrounding oceans.

Gagnasafn [GDB] NI_J100v_Vesturgosbelt_1.utg: Jarðfræðikort af Vesturgosbelti Íslands í mælikvarði 1:100.00, 1. útg. [Geological map of the Western Volcanic Zone of Iceland in the scale of 1:100.000, 1st ed.] Kortið sýnir jarðlög, gíga, höggun, strik og halla, framhlaup og niðurföll, steingervinga, jökulrákir, jökulgarða, jökulkembur, malarása og fornar strandlínur stöðuvatna. Jarðlög eru flokkuð eftir aldri, gerð og samsetningu. Kortið var unnin í samstarfi Náttúrufræðistofnunar Íslands og Íslensku Orkurannsoknastofa. Tilvísun: Birgir V.

[The map displays bedrock geology, volcanic craters, tectonics, strike and dips, landslides and collapse pits, fossils, glacial striations, glacial moraines, flutes, eskers and ancient lake strandlines. Bedrock is classified by age, type, and composition. The map was completed in a collaborative project between the Icelandic Institute of Natural History and the Icelandic Geosurvey.

GE.Bedrock 1:1 000 000 is a transformed version of the SGU product Bedrock1:1 million with the purpose to conform to the Inspire data specification for Geology encoded according to GeoSciML 4.0. It is also a contribution to the OneGeology initiative (www.onegeoloy.org). Data is represented in a two-dimensional model of the top of the bedrock, describing identified geological units geometry, the material composition of the units and geologic events that has acted on the units. Shear displacement structures like faults on the top of bedrock are also included in the model. The main features of the bedrock geology of Sweden is represented in the produkt and since it is based on compilation of bedrock maps of different scales, age and quality the accuracy of the data varies within the dataset. The product is produced for presentation at the scale of 1:1 miilion which means that some units are heavily generalized.

[Bedrock is classified by age, type, and composition. The data follows the ÍST120:2012 data standard with these additional feature attributes: myndunKodi = short code denoting the rock formation type, myndunIS = short Icelandic name for rock formation, myndunEN = short English name for rock formation, eldstodNafn = name of the volcanic system, kenni = short codename for interglacial and postglacial lavas, aldur = age range. New code for feature attribute 'Tegund storkubergs' (tegStorkubergs): dbas = porphyrytic basalt.]
