1. 1. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Torpikay Azizi; [2023-08-18]
   Nyckelord :PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

   Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

3. 2. Enhancing Geophysical Applications with Electrical Resistivity Tomography Inversion : Uncovering the mysteries that lies beneath us

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Anton Morian; [2023]
   Nyckelord :Resistivity inversion; Filtering; 3D visualisation;

   Sammanfattning : Geophysical methods have been widely used to investigate the subsurface in various ap-plications, such as mineral exploration, geotechnical and environmental studies. Among these methods, electrical resistivity tomography (ERT) has gained popularity due to its non-invasive and high-resolution capability in mapping subsurface resistivity variations. LÄS MER

4. 3. The Promise of a Green Revolution : Conceptions of climate change and sustainability in local movements objecting to mining establishment

   Master-uppsats, Uppsala universitet/Institutionen för kulturantropologi och etnologi

   Författare :Caroline Reinhammar; [2023]
   Nyckelord :;

   Sammanfattning : This study explores how vernacular understandings of climate change and sustainability are formed in relation to local disputes concerning mineral exploration. In a search for a solution to climate change, the interest in rare earth elements (REEs), and other metals used in green technology has resulted in granting mining companies processing concessions in Sweden.

   Nyckelord :geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Sammanfattning : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. LÄS MER

7. 5. MINERAL RENTS AND WEALTH : AN ANALYSIS OF THE DIAMOND MARKET AND THE POTENTIAL TAX SPACE 2010-2019

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

   Författare :Anton Löf; [2022]
   Nyckelord :;

   Sammanfattning : The aim of this thesis is to analyse resource rents in the diamond industry. Based on extensive datasets and a discussion of all relevant costs, resource rent statistics in the diamond industry is examined on a global level for the period 2010-2019. Resource rents give an indication of the available space for taxation. LÄS MER
