1. 16. Petrography, alteration and structure of the Bronäs Zn-Pb-Ag deposits, Bergslagen, Sweden

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Tom Turner; [2020]
   Keywords : Bronäs; Sala;

   Abstract : This report aims to characterize the alteration styles and mineralization of the Zn-Pb-Ag Bronäs deposit, in the Sala area of the Bergslagen mining district, Sweden.  It presents data collected through 237m of lithological logging and subsequent lithogeochemical data, which, coupled with thin section and SEM analysis has led to the first geological descriptions of the rocks in the deposit.

3. 17. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

   University essay from Lunds universitet/Geologiska institutionen

   Author : Dino Leopardi; [2020]
   Keywords : Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

   Abstract : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. READ MORE

4. 18. Assessment of Machine Learning Applied to X-Ray Fluorescence Core Scan Data from the Zinkgruvan Zn-Pb-Ag Deposit, Bergslagen, Sweden

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Frans Filip Simán; [2020]
   Keywords : XRF; X-Ray Fluorescence; Core Scanning; Machine Learning; AI; SOM; Self Organising Map; CART; Classification and Regression Trees; K-means clustering; Rock Classification; Virtual Core Logging; Zinkgruvan;

   Abstract : Lithological core logging is a subjective and time consuming endeavour which could possibly be automated, the question is if and to what extent this automation would affect the resulting core logs. This study presents a case from the Zinkgruvan Zn-Pb-Ag mine, Bergslagen, Sweden; in which Classification and Regression Trees and K-means Clustering on the Self Organising Map were applied to X-Ray Flourescence lithogeochemistry data derived from automated core scan technology.

5. 19. Förmögenhetsutveckling vid skogsöverlåtelser : överlåtelseformens påverkan på parternas finansiella ställning över tid

   University essay from SLU/Dept. of Economics

   Author : Carl Filip Hjälte; Magnus Wretemark; [2019]
   Keywords : generationsskifte; skog; förmögenhetsutveckling; skogsägande; skogsöverlåtelse;

   Abstract : En stor andel av svenskt skogsbruk bedrivs inom ramarna för familjeägda, ofta mindre, skogsfastigheter. Generationsskiftena utgör en utmaning för dessa familjeskogsbruk, bland annat på grund av de stora värdena i fastigheten, de långa omloppstiderna, skattelagstiftningen och syskons lagenliga krav på kompensation.

6. 20. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Filip Ivarsson; [2019]
   Keywords : Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

   Abstract : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. READ MORE
