Scalability of lineament and fracture networks within the crystalline Wiborg Rapakivi Batholith, SE Finland
(2020-01-30)
Multiscale lineament and fracture extraction conducted within the Wiborg Rapakivi Batholith offers insights both into the brittle bedrock structures of the batholith and to the scale-dependence of lineament and fracture ...
STRUCTURAL CONTROL OF THE OROGENIC GOLD DEPOSITS IN KULLAA, SW FINLAND
(2020-05-18)
The Pomarkku block in SW Finland comprises four known orogenic gold mineralizations in the vicinity of Kullaa municipality. Previous studies have focused on the geochemical features of the mineralizations whereas the ...
Hydrothermal alteration of medium-grade metamorphic rocks of Metsämonttu VMS deposit, southern Finland : A comparative portable XRD and near-infrared spectroscopy analysis
(2021-12-28)
Hydrothermal alteration processes are connected to the formation of many economically important ore deposits. This study represents a comparative portable XRD (pXRD) and near-infrared (NIR) spectroscopy analysis of four ...
Footwall basal thrust, Sakatti Cu-Ni-PGE deposit, Northern Finland
(2021-06-08)
The Sakatti Cu-Ni-PGE deposit, located ~20 km northeast from the municipality of Sodankylä, has been formerly investigated mainly for its economic potential, while the structural character of the deposit has been left in ...
3D-modelling of fault-induced small-scale secondary fracturing in crystalline rocks
(2021-07-13)
The objective of this Thesis was to develop new methods to model the microstructures within the bedrock, as these models improve the understanding of the properties of the micro-scale fracture networks and could be further ...
Structural control of dykes and veins in the Mansikka-aho area, Evijärvi, Western Finland
(2021-07-09)
The northern part of the Aho metavolcanic belt within Ostrobothnia schist belt has been explored intensively because of the vicinity of the discovered spodumene pegmatite deposits in the Kaustinen area. The aim of this ...
Metallogeny of remobilised komatiite-associated Sika-aho nickel deposit, Kuhmo greenstone belt
(2022-12-21)
Growing demand of nickel requires new discoveries to be made, highlighting the need for better understanding of mineralisation processes. All Archaean nickel deposits are invariably metamorphosed and deformed, which has ...
Structural control of gold deposits in the Huittinen area, SW Finland
(2022-12-27)
The purpose of this thesis is to investigate the relationship between bedrock structures and orogenic gold deposits in the Huittinen area, southwestern Finland by the means of bedrock mapping and structural analysis. The ...
Correlation of bedrock outcrop structures with subsurface data - with emphasis on the needs of geoenergy research
(2023-02-28)
The demand of energy is constantly increasing in this rapidly developing world. At the same time, the transition of contaminant ways of energy production is more often replaced by production methods that are using renewable ...
Petrography and genesis of Vaajasalmi graphite targets in Rautalampi Central Finland
(2022-10-21)
Natural graphite is listed on the European Union's top 30 most critical minerals and is mainly imported outside of Europe. Graphite value and demand increase are driven by electrification since its extraordinary features ...
