3. 2. Resolving temporal links between the Högberget granite and the Wigström tungsten skarn deposit in Bergslagen (Sweden) using trace elements and U-Pb LA-ICPMS on complex zircons

   University essay from Lunds universitet/Geologiska institutionen

   Author : Anders Plan; [2020]
   Keywords : Bergslagen; Wigström; Högberget; geochronology; geochemistry; U-Pb; REE; trace element; zircon; hydrothermal zircon; LA-ICPMS; SEM; skarn; tungsten; wolfram; scheelite; deposit; ore; critical raw material; Earth and Environmental Sciences;

   Abstract : Combined U-Pb and REE trace element LA-ICPMS analyses were performed on zircons, from the scheelite-bearing Wigström skarn, associated micro-granitic dykes and the highly evolved parental Högberget (sensu stricto) granite. Combined systematic of zircon typology and microtextures, trace elements and isotopic chemistry suggest the presence of several diverse zircon types, spanning from early- to late- magmatic stage into a hydrothermal stage.
