Spatial modeling techniques for mapping and characterization of acid sulfate soils
(Åbo Akademi - Åbo Akademi University, 2015-04-08)
Acid sulfate (a.s.) soils constitute a major environmental issue. Severe ecological damage results from the considerable amounts of acidity and metals leached by these soils in the recipient watercourses. As even small hot ...
Analog models of the lateral spreading of a thick three-layer crust : implications for the Svecofennian orogen in Finland
(Åbo Akademi - Åbo Akademi University, 2016-09-23)
Our knowledge of the crustal structure of the Precambrian Svecofennian orogen has been enhanced during the last decade. Much of the new knowledge is due to the deep seismic reflection studies (Finnish Reflection Experiments; ...
Effects of anthropogenic and natural hydrological changes on the behavior of the acidic metal discharge from acid sulfate soils in a river- and lake system in western Finland
(Åbo Akademi - Åbo Akademi University, 2013-11-22)
Mantle- and crust-derived magmatism in the southern Fennoscandian Shield at c. 1.8 Ga; evidence from geochemistry, isotopes and geochronology
(Åbo Akademi - Åbo Akademi University, 2010-03-26)
Structure-related magnetic fabric studies : implications for deformed and undeformed Precambrian rocks
(Åbo Akademi - Åbo Akademi University, 2013-11-01)
The aim of this thesis research was to gain a better understanding of the emplacement of rapakivi granite intrusions, as well as the emplacement of gold-bearing hydrothermal fluids in structurally controlled mineralizations. ...
Geological and mineralogical aspects on mineral carbonation
(Åbo Akademi - Åbo Akademi University, 2017-01-03)
The mineralogical features that characterise each individual mineral and rock also influence every process they are part of. This is also the case with “the ÅA route” mineral carbonation method that has been under development ...
Element speciation and behaviour in metal-rich Boreal river and estuarine systems using ultrafiltration and chemical modelling
(Åbo Akademi - Åbo Akademi University, 2012-11-16)
The bioavailability of metals and their potential for environmental pollution depends not simply on total concentrations, but is to a great extent determined by their chemical form. Consequently, knowledge of aqueous ...
Surface studies of limestones and dolostones : characterisation using various techniques and batch dissolution experiments with hydrochloric acid solutions
(Åbo Akademi - Åbo Akademi University, 2015-01-30)
In this thesis, stepwise titration with hydrochloric acid was used to obtain chemical reactivities and dissolution rates of ground limestones and dolostones of varying geological backgrounds (sedimentary, metamorphic or ...
