  1. 1. 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

  2. 2. Tracing the Origin of Metasedimentary Rocks in the Faroe-Shetland Basin

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sarah Eriksson; [2016]
    Keywords : Faroe-Shetland basin; Isotope correlation; metasediments; element analysis; Färö-Shetland bassängen; isotopkorrelation; metasediment; geokemisk analys;

    Abstract : The Faroe-Shetland region has been exposed to a long history of tectonic events and the geology in the area is rather complex. This history has led to the formation large metasedimentary deposits, though the origin of these deposits is not yet fully understood. Possible source areas are Greenland, Norway and Scotland.

  3. 3. REE mineralisation and metasomatic alteration in the Olserum metasediments

    University essay from Lunds universitet/Geologiska institutionen

    Author : Wayne Fullerton; [2014]
    Keywords : metasediment; metasomatism; mineralisation; monazite; Olserum; REE; xenotime; Earth and Environmental Sciences;

    Abstract : The Olserum mineralisation is situated in the metasediments of the Västervik formation, which repre-sents the southernmost continental margin of the Svecokarelian Domain. After deposition between 1.88 – 1.85 Ga these sediments were subsided to a depth of about 10 km and intruded by a series of granitoid melts. READ MORE

  4. 4. Monazite in metasediments from Stensjöstrand : a pilot study

    University essay from Lunds universitet/Geologiska institutionen

    Author : Andreas Olsson; [2013]
    Keywords : pilot study monazit; Stensjöstrand; Sveconorwegian orogen; monazite; metasediments; metasediment; Sveconorvegiska orogenesen; pilotstudie; Earth and Environmental Sciences;

    Abstract : Monazit är ett Ree– och Th-bärande fosfatmineral som förekommer i vissa magmatiska och metamorfa bergarter. Mineralet är användbart för datering av den metamorfa utvecklingen och kan bidra till att yt-terligare karaktärisera metamorfosen i en bergart, detta genom att man undersöker zoneringar i kristallerna.

  5. 5. Metamorphic study of metasediment from the Kangilinaaq Peninsula, West Greenland

    University essay from Lunds universitet/Geologiska institutionen

    Author : Lina Åberg; [2005]
    Keywords : West Greenland; Nagssugtoqidian Orogen; supracrustal rocks; Kangilinaaq Peninsula; metasedimentary rocks; pelites; correlation; Västra Grönland; Nagssugtoqidiska orogenesen; suprakrustala bergarter; metasedimentära bergarter; peliter; korrelation; Earth and Environmental Sciences;

    Abstract : The Nagssugtoqidian Orogen is represented by an approximately 300 km wide Palaeoproterozoic deformation and metamorphic belt that stretch through the southern and middle parts of west Greenland. The Orogen is characterized and dominated by metamorphosed Archaean orthogneisses with minor supracrustal sequences. READ MORE
