   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Klara Skoog; [2022]
   Nyckelord :Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

   Sammanfattning : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. LÄS MER

3. 2. Geochemical tracing of Arsenic sources in groundwater at the remediated Storliden mine, Skellefte district

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Matilda Edvardsson; [2021]
   Nyckelord :Arsenic; groundwater; Sulfide oxidation; Arsenopyrite; Storliden; remediation; Arsenik; grundvatten; sulfidoxidation; Arsenikkis; Storliden; efterbehandling;

   Sammanfattning : The Swedish mining industry has changed from the historical situation with several smaller mines to the present situation with a few, bigger mines. This results in presence of abandoned mines around Sweden. Remediation of mines is regulated by legislation and the present demands are considerably higher than it was some decades ago. LÄS MER

   Sammanfattning : Ädelfors is situated ca 17 km east of Vetlanda, Jönköping County, in the N-S striking Trans-scandinavian igneous belt and is a part of the NE-SW striking 1.83-1.82 Ga Oskarshamn-Jönköping belt emplaced during a continental subduction towards the Svecofennian continental margin. The continental arc hosts the 1. LÄS MER

5. 4. Deformation, metamorphism and remobilisation in the Hornkullen polymetallic deposit, western Bergslagen, Sweden
