  1. 1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
    Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

    Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

  3. 2. A geological investigation on bedrock suitability for mineral carbonation conducted in the south central part of Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Edvard Pearson; [2023]
    Keywords : Mineral carbonation; geological investigation; Åsensbruk; Falun; Grums; Öje; Skutskär;

    Abstract : Increasing global temperatures due to anthropogenic emissions of greenhouse gases is one of our times most dire and urgent challenges to overcome if we are to achieve a sustainable healthy planet. The primary way of accomplishing this is by reducing the amount of released greenhouse gases. READ MORE

  4. 3. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    University essay from KTH/Kemiteknik

    Author : Gisela Engström; [2022]
    Keywords : Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Abstract : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. READ MORE

  5. 4. Geochemical and Mineralogical Comparison of XRT-XRF Scanning Technology Versus Traditional Analysis of Drill Core from the Assarel Porphyry Copper-Gold Deposit (Panagyurishte District, Bulgaria)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Diego Delgado Yanez; [2020]
    Keywords : Assarel porphyry copper; GeoCore X10; Sustainable mining; XRT XRF; mineral characterization; geochemical characterization; X-MINE Project;

    Abstract : Ongoing, environmental and economic matters related to mining sustainability and its impacts are leading to the search for new ways to asses and extract commodities more efficiently. A key aspect in the shift to more sustainable mining is the rapid, digital characterization of orebody mineralogy and geochemistry to help optimize the extractive process. READ MORE

  6. 5. Holocene lake-level changes in the Siljan Lake District – Towards validation of von Post’s drainage scenario

    University essay from Lunds universitet/Geologiska institutionen

    Author : Savvas Paradeisis-Stathis; [2020]
    Keywords : Lake Siljan; Dalarna; basin isolation; catastrophic drainage; early Holocene; lake sediments; XRF scanning; C N ratio; magnetic susceptibility; pollen; Ancylus Lake; Earth and Environmental Sciences;

    Abstract : The Dalarna province in south-central Sweden shows a great variety of geological evidence from the Late Quaternary. A peculiar deglaciation pattern, along with unique hydrological conditions, has left a lot of space for speculations over the palaeoenvironmental conditions during the early Holocene. READ MORE
