ni_j100v Berggrunnur á Vesturgosbelti – 1:100.000

Þekja [layer] j100v_vesturgosbelti_berggrunnur_1utg_fl:

Gögn fyrir berggrunn ásamt nútímahraunum. [Data showing the bedrock geology, including Holocene lavas.]

Berggrunnur er flokkaður eftir aldri, gerð og samsetningu. Gögn eru flokkuð eftir ÍST120:2012 staðlinum, nema fitjueigindir:

myndunKodi = stuttur kóði sem táknar gerð bergmyndunar,

myndunIS = stutt íslenskt heiti fyrir bergmyndun,

myndunEN = stutt enskt nafn á bergmyndun,

eldstodNafn = nafn eldstöðvakerfis,

kenni = stuttur kóði fyrir hlýskeiðishraun og nútímahraun,

aldur = aldursbil,

Nýr kóði fyrir fitjueigindina 'Tegund storkubergs' (tegStorkubergs): dbas = dílabasalt.

[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.]

Statement: Gögn úr vettvangsvinnu jarðfræðinga NÍ og ÍSOR, ásamt kortlagningu og gögnum S. P. Jakobssonar (2019) af Vesturgosbeltinu unnin á NÍ. Birt jarðfræðikort og greinar frá Kjartansson (1965), Sæmundsson and Noll (1974), Johannesson (1994) og Sinton et al. (2005). Þekja nútímahrauna unnin á NÍ í tengslum við sérstaka vernd náttúrfyrirbæra (2017), en endurskoðuð og bætt í samræmi við vettvangsvinnu og jarðfræðikortlagningu Vesturgosbeltisins. Eldri gögn kortsins hafa verið yfirfarin og endurskoðuð.

[Data is compiled from field observations by geologists at NÍ and ÍSOR, as well as previously published and unpublished datasets including Kjartansson (1965), Sæmundsson and Noll (1974), Johannesson (1994), Jakobsson (2019), and Sinton et al. (2005). Postglacial lava data was compiled at NÍ (NÍ-Kortasjá ‚Sérstök vernd náttúrufyrirbæra‘), revised according to recent fieldwork. The map has been checked and reviewed internally.]
