1. 11. Hydrothermal alteration and lithogeochemical marker units at the Svärdsjö Zn-Pb-Cu deposit, Bergslagen, Sweden, and their implications for exploration

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Anton Fahlvik; [2018]
   Keywords : Hydrothermal alteration; Lithogeochemistry; Exploration; Bergslagen; Svärdsjö;

   Abstract : In exploration, a lithogeochemical approach can be used to aid the characterisation of rocks surrounding metamorphosed and hydrothermally altered deposits. Accurate description of the geological setting of deposits is crucial for understanding the ore forming processes and identifying targets for exploration. READ MORE

3. 12. A Petrological Investigation of the Host Rocks for the Kuj-Kiirunavaara Ore

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Holger Sandberg; [2018]
   Keywords : Kiirunavaara; optical mineralogy; hydrothermal alteration; electron microprobe; Kiirunavaara; optisk mineralogi; hydrotermal omvandling; elektron-mikrosond;

   Abstract : The Kiirunavaara mine hosts one of the world’s largest apatite-iron ore mineralisations. This ore body has been subject to large amounts of research as well as extensive mining. The ore body is situated between the syenitic foot wall and the rhyodacitic hanging wall, of which consists of differing mineralogy and characteristics. READ MORE

4. 13. Characterization of the Hydrothermal Alteration around the Björkdal Au Deposit, Skellefte District, Sweden

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Madeleine Erneholm; [2017]
   Keywords : Gold Ore; Mine; Skellefte District; Sweden; Quartz Lode; Hydrothermal Alteration; Petrography; Lithogeochemistry; Intrusion-related Gold;

   Abstract : Sixteen samples from 8 locations within and surrounding the Björkdal mine area in northern Sweden were chosen in order to reevaluate and characterize previous interpretations of the lithology and hydrothermal alteration. Geochemical analysis by ICP-MS was made in order to chemically classify the lithology of the area and petrological studies were made by study of thin sections and core logging. READ MORE

5. 14. Defining The Geochemical Footprint For Gold Mineralisation Around Birthday Reef.Reefton Goldfield, New Zealand

   University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

   Author : Jonathan Hamisi; [2016]
   Keywords : Orogenic gold; hydrothermal alteration; Reefton; mass changes; geochemical footprint; vectors; exploration; Blackwater;

   Abstract : Abstract Orogenic gold deposits from the Reefton goldfield in New Zealand hosted in Ordovician metasediments of the Greenland group have produce 67 tons of gold before 1951. The Blackwater mine in Waiuta account for about 1/3 of the gold production at Reefton prior 1951. READ MORE

6. 15. An Analysis and Interpretation of the Geoscience BC Trek Project Till Geochemical and Mineralogical Data to Determine the Surficial Geochemical Expression of Bedrock Au-Ag-Cu-Mo Mineralization on the Nechako Plateau, British Columbia, Canada.

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Karin Öberg; [2016]
   Keywords : British Columbia; till; gold; copper; mineralization; British Columbia; morän; mineralisering; guld; koppar;

   Abstract : The mineral exploration in the interior of British Columbia is challenged by an extensive coverage of glacial sediments. The Geoscience British Columbia (GBC) Targeting Resources through Exploration and Knowledge (TREK) Survey has since 2013 collected till samples in the northern interior plateau of British Columbia, covering an area of approximately 25,000km2.
