MARC recordThe Middagsberget gold occurrence in northern Sweden / Heikki Markkula.
| Title: | The Middagsberget gold occurrence in northern Sweden / Heikki Markkula. |
| Author(s): | Markkula, Heikki. |
| Date: | 1991. |
| In: | Geologiska Föreningens i Stockholm Förhandlingar. (1991.), Vol. 113(1) (1991) |
| Abstract: | In Skellefte sulphide ore district. Quartz fracture-fillings in dilatant zones within ore-hosting diorite as well as in surrounding, strongly folded metasedimentary and metavolcanic rocks, suggest epigenetic charcter of emplacement. Alteration assemblages and gold-sulphide paragenesis favour multi-stage hydrothermal gold deposition. Most of gold occurs as native gold in minor droplets and interfillings within arsenopyrite crystals. Middagsberget deposit is "new" type in northern Sweden. |
| Notes: | Geologiska Föreningens i Stockholm Förhandlingar. Vol. 113(1) :56-58 (1991). |
