The Jokkmokk granitoid, an example of 1.88 Ga juvenile magmatism at the Archaean-Proterozoic border in northern Sweden / Christina Lundmark, Kjell Billström, Pär Weihed.
Title: | The Jokkmokk granitoid, an example of 1.88 Ga juvenile magmatism at the Archaean-Proterozoic border in northern Sweden / Christina Lundmark, Kjell Billström, Pär Weihed. |
Author(s): | Lundmark, Christina. Billström, Kjell. Weihed, Pär. |
Date: | 2005. |
In: | GFF. (2005.), Vol. 127(2) (2005) |
Abstract: | Describes Jokkmokk granitoid (exposed in large plutonic massif north-west of Jokkmokk in northern Sweden) as light grey to white, fine-grained, with megacrysts of feldspar and glomeroporphyritic hornblende and biotite. Notes granitoid's unique calc-alkaline to alkali-calcic, metaluminous to weakly peraluminous, character with moderate LREE enrichment and flat HREE pattern, and flat to slightly positive Eu-anomaly. U-Pb TIMS zircon dating of granitoid gives age of 1883 Ma, coeval with emplacement of Haparanda suite. |
Notes: | GFF. Vol. 127(2) :83-98 (2005). |
