2. 1. Seismic investigations and physical property studies of natural resources in Finland and Sweden : Efficient exploration of groundwater and mineral resources

   Author : Georgiana Maries; Alireza Malehmir; Christopher Juhlin; Musa Manzi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; seismic refraction; esker; glacial sediments; iron-oxide; hardrock; efficient exploration; physical property; forward modeling; seismic quality factor; Finland; Sweden; Bergslagen;

   Abstract : Natural resources, such as mineral deposits and groundwater in particular, are crucial for our society, as the world prepares itself for a smooth transition towards green technologies and decarbonization. Apart from extraction and use, innovative mineral exploration solutions are needed to complete the full value chain and to achieve the sustainable development goals. READ MORE

4. 2. Application of the Seismic Reflection Method in Mineral Exploration and Crustal Imaging : Contributions to Hardrock Seismic Imaging

   Author : Omid Ahmadi; Christopher Juhlin; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seismic reflection; Hardrock; Mineral exploration; Crustal imaging; Interpretation; Modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : The seismic reflection method has been used extensively in mineral exploration and for imaging crustal structures within hardrock environments. In this research the seismic reflection method has been used and studied to address problems associated with hardrock settings. READ MORE

5. 3. Seismics, 2D and 3D Inversion of Magnetotellurics : Jigsaw pieces in understanding the Skellefte Ore District

   Author : María de los Ángeles García Juanatey; Ari Tryggavson; Ute Weckmann; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetotellurics; 2D inversion; 3D inversion; hard rock seismics; mineral exploration; integrated geophysics; 4D modeling; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : The Skellefte District (SD) is one of the richest metallogenic mining areas in Sweden. The main deposits consist of volcanic-hosted massive sulphides (VHMS) rich in zinc, copper, lead, gold and silver, that have been explored and mined for more than a century. READ MORE

6. 4. Seismic Exploration Solutions for Deep-Targeting Metallic Mineral Deposits : From high-fold 2D to sparse 3D, and deep-learning workflows

   Author : Magdalena Markovic; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exploration; Seismic; Mineral Deposits; Diffraction; Deep learning;

   Abstract : Mineral exploration has in recent years moved its focus to greater depths than ever before, particularly in brown fields. Exploring new deposits at depth, if economical, would not only expand the life of mine but also provide minimal environmental impacts. It allows the existing mining infrastructures to be used for a longer period. READ MORE

7. 5. 2D and 3D Seismic Surveying at the CO2SINK Project Site, Ketzin, Germany: The Potential for Imaging the Shallow Subsurface

   Author : Sawasdee Yordkayhun; Christopher Juhlin; Charlotte Krawczyk; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inversion; Traveltime tomography; 3D seismic surveys; Seismic velocity; Seismic source; CO2SINK project; Geophysics; Geofysik;

   Abstract : Seismic traveltime inversion, traveltime tomography and seismic reflection techniques have been applied for two dimensional (2D) and three dimensional (3D) data acquired in conjunction with site characterization and monitoring aspects at a carbon dioxide (CO2) geological storage site at Ketzin, Germany (the CO2SINK project). Conventional seismic methods that focused on investigating the CO2 storage and caprock formations showed a poor or no image of the upper 150 m. READ MORE
