  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.

    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

  4. 4. Characterizing magnetic susceptibility and remanent magnetization of magnetite and hematite rich drill-core samples at Blötberget

    University essay from Uppsala universitet/Geofysik

    Author : Andreas Bjork; [2018]
    Keywords : Verwey; Morin; Curie; Néel; magnetite; hematite; alteration; iron-ore; quality control; kappabridge; hysteresis; susceptibility; anisotropy; Verwey; Morin; Curie; Néel; magnetit; hematit; oxidation; järnmalm; kvalitetskontroll; kappabridge; hysteresis; susceptibilitet; anisotropi;

    Abstract : Laboratory magnetic measurements are used to develop a methodology to characterize the Kiruna-type Rare Earth Elements (REE) bearing apatite iron-oxide deposits at Blötberget in central Sweden. This high-grade ore deposit is known to have sharp boundaries between lens shaped main ore bodies of magnetite-rich ore, and a complex hematite-rich ore associated with pegmatites and skarn formation.

  5. 5. An environmental magnetic study of a marine sediment core from Disko Bugt, West Greenland : implications for ocean current variability

    University essay from Lunds universitet/Geologiska institutionen

    Author : Jonas Persson; [2008]
    Keywords : Disko Bugt; mineral magnetism; environmental magnetism; magnetic susceptibility; ARM; SIRM; IRM; HIRM; miljömagnetism; magnetisk mottaglighet; Earth and Environmental Sciences;

    Abstract : An 11 m long marine sediment core was collected during a June-July 2007 scientific cruise with the German research vessel R/V Maria Sibylla Merian to the area of Disko Bugt, western Greenland. The core, designated 343340-6-1, was examined using environmental magnetic methods and X-ray fluorescence. READ MORE
