Combined X-Ray Computed Tomography and X-Ray Fluorescence Drill Core Scanning for 3-D Rock and Ore Characterization: Implications for the Lovisa Stratiform Zn-Pb Deposit and Its Structural Setting, Bergslagen, Sweden
Luth, Stefan; Sahlström, Fredrik; Bergqvist, Mikael; Hansson, Alexander; Lynch, Edward P.; Sädbom, Stefan; Jonsson, Erik; Andersson, Stefan S.; Arvanitidis, Nikolaos (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-29)We present the results of a pilot study that integrates automated drill core scanning technology based on simultaneous X-ray computed tomography (XCT) and X-ray fluorescence (XRF) analyses to provide high-spatialresolution (<0.2 mm) information on 3-D rock textures and structures, chemical composition, and density. Testing of its applicability for mineral exploration and research was performed by ... -
Mineral paragenesis and sulphide trace element distribution in the metamorphosed Lovisa Zn-Pb deposit, Bergslagen (Sweden), as revealed by 3D X-ray tomography, ore petrography and LA-ICP-MS analysis
Andersson, Stefan S.; Sahlström, Fredrik; Jonsson, Erik; Luth, Stefan; Lynch, Edward P.; Högdahl, Karin; Zack, Thomas; Gies, Nils; Sädbom, Stefan; Alexander Hansson, K.S.; Bergqvist, Mikael (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-29)This study encompasses the ore mineralogy, textures and sulphide trace element chemistry of the Palaeoproterozoic Lovisa stratiform Zn-Pb deposit and the stratigraphically underlying Lovisa Fe Formation in the Bergslagen ore province (Sweden). We investigate the relative timing of formation and subsequent modifications of its ores in relation to the c. 1.87–1.80 Ga Svecokarelian orogeny. The Lovisa ...
