  1. 1. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    University essay from Uppsala universitet/Geofysik

    Author : Dimitra Daniil; [2021]
    Keywords : magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Abstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.

  2. 2. Magnetic Mineralogy of Nb-bearing Carbonatites from Oldoinyo Dili (Tanzania)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Julia Frejd; [2021]
    Keywords : carbonatites; niobium; rare earth elements; Oldoinyo Dili; magnetic properties; karbonatiter; niob; rare earth elements; Oldoinyo Dili; magnetiska egenskaper;

    Abstract : Niobium (Nb) and Rare Earth Elements (REE’s) have in recent years received considerable attention because of their importance to the modern technical industry, and more specifically the enhanced sustainability that comes with them. The main source for Nb and REE’s on Earth are carbonatites and associated alkaline silicate rocks. READ MORE

  3. 3. Rock-magnetic and Soil Organic Carbon Proxies of Climate Change from Loess – Aeolian Sediments of Brittany, France

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Carolina Kouns; Yael Margulis; [2021]
    Keywords : loess; LOI; magnetic susceptibility; Brittany; Quaternary; löss; LOI; magnetisk susceptibilitet; Bretagne; kvartär;

    Abstract : The aeolian sediment loess, which consists of mineral dust, is one of the most detailed terrestrial record of both global and regional climate changes. As climate changes in the past cover a much wider range of climate variability than humans have directly recorded, the soil memory of loess is vital for understanding the Earth’s climate system.

  4. 4. Investigating the Magnetic Susceptibility of Cornish Loess as a Tool for Understanding the Palaeoclimate of SW England

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Love Tingdal; [2020]
    Keywords : loess; palaeoclimate; Lizard Peninsula; Isles of Scilly; palaeoprecipitation; magnetic susceptibility; loess; paleoklimat; Lizard-halvön; Scillyöarna; historisk årsmedelnederbörd; magnetisk susceptibilitet;

    Abstract : Loess is a silty material produced via glacial grinding and its deposition is usually associated with colder periods when there is a considerable increase in atmospheric dust transport. The magnetic susceptibility of loess-palaeosol sequences has been the subject of extensive research within palaeoclimatology as it has proven to be reliable climate proxy. READ MORE

  5. 5. Petrophysic of the Host-rock to the Ore in the Lovisa Mine, Bergslagen

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oscar Gilljam Päärt; [2019]
    Keywords : Petrophysics; density; magnetic volume susceptibility; natural remanent magnetization; Bergslagen; lithology; Petrofysik; densitet; magnetisk susceptibilitet; naturlig magnetisk remanens; Bergslagen; lithologi;

    Abstract : The Bergslagen region has three base-metal mines operating today, and one of them is the Lovisa mine, which host a Zn-Pb-Ag deposit. The Lovisa mine is located in the Guldsmedshyttan area north of Lindesberg. READ MORE
