4. Assessment of Machine Learning Applied to X-Ray Fluorescence Core Scan Data from the Zinkgruvan Zn-Pb-Ag Deposit, Bergslagen, Sweden
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : Lithological core logging is a subjective and time consuming endeavour which could possibly be automated, the question is if and to what extent this automation would affect the resulting core logs. This study presents a case from the Zinkgruvan Zn-Pb-Ag mine, Bergslagen, Sweden; in which Classification and Regression Trees and K-means Clustering on the Self Organising Map were applied to X-Ray Flourescence lithogeochemistry data derived from automated core scan technology.

5. Mineralogical and Geochemical characterization of the Fe-Cu-Occurrence and associated Hanging wall and Footwall Alteration halo of the Viscaria D-Zone, Kiruna District, Northern Sweden
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : Northern Norrbotten County is one of the three major ore producing districts in Sweden. Based on the predominance of epigenetic Cu-Au and Fe-oxide mineralization this region is regarded as a typical IOCG province. The massive to layered Viscaria Cu-deposit is proposed to be a VMS deposit of Besshi-type and is unique in deposit type of the region. READ MORE
