  1. 36. Methods for rockfall risk assessment and estimation of runout zones: A case study in Gothenburg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Laura Catalina Agudelo Motta; [2020]
    Keywords : Rockfall hazard; rockfall simulation; Gothenburg; Fjällbo; runout zones; Earth and Environmental Sciences;

    Abstract : Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones.

  3. 37. Temporal and genetical constraints of the Cu-Co Vena-Dampetorp deposit, Bergslagen, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Dino Leopardi; [2020]
    Keywords : Bergslagen; Vena; Dampetorp; Cu-Co; sulphide melting; Bastnäs-type; cobaltite; arsenopyrite; titanite dating; sulphide mineralization; sulphide re-mobilisation.; Earth and Environmental Sciences;

    Abstract : The Bergslagen Province is known for containing major Zn-Pb-Ag and Zn-Pb-Cu-Ag sulphide mineralizations with associated iron-oxide skarns and a lot of research have focused on understanding them. However, Cu-Co deposits like the Vena-Dampetorp deposit have received less attention. READ MORE

  4. 38. 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 miljöteknik

    Author : Frans Filip Simán; [2020]
    Keywords : XRF; X-Ray Fluorescence; Core Scanning; Machine Learning; AI; SOM; Self Organising Map; CART; Classification and Regression Trees; K-means clustering; Rock Classification; Virtual Core Logging; Zinkgruvan;

    Abstract : 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. 39. Suggestions for the development of a quantitative framework of Terroir Analysis in Swedish Vineyards

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aharon Gurwicz; [2020]
    Keywords : Terroir; Wine; Vineyard; Earth and Environmental Sciences;

    Abstract : Wine is an important cultural crop and is grown in vineyards that sometimes claim to have a unique "terroir" - a specific taste and character based on their physical attributes and location. Regulations and previously published work are not easily available, into how to measure and assess this terroir. READ MORE

  6. 40. The Impact of Fracture Orientation on the Choice of Grout Fan Geometry - a Statistical Analysis

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Osterman; [2019]
    Keywords : Rock Fissure Grouting; Grout Fan Geometry; Geology; Discrete Fracture Network; Sprickinjektering i berg; skärmgeometri; geologi; diskreta spricknätverk;

    Abstract : Water ingress into rock tunnels is a problematic phenomenon – especially in urban areas – as a lowered groundwater table may cause harmful settlements. Furthermore, too much ingress can be an incentive for the environmental court to halt the tunnel process, in order to protect the nature as part of a national interest. READ MORE
