1. Constraining the Uplift History of the Al Hajar Mountains, Oman
Sammanfattning : Mountain building is the result of large compressional forces in the Earth’s crust where two tectonic plates collide. This is why mountains only form at plate boundaries, of which the Al Hajar Mountains in Oman and the United Arab Emirates is thought to be an example of. LÄS MER
2. Tectonic implications of ca. 1.45 Ga granitoid magmatism at the southwestern margin of the East European Craton
Sammanfattning : Between ca 1.53 and 1.40 Ga, the southwestern margin of the East European Craton was subjected to extensive magmatism and deformation. While various suites of anorthositic, mangeritic and charnockitic-granitic rocks were emplaced between ca. LÄS MER
3. Cryptic Orogeny : uplift of the Al Hajar Mountains at an alleged passive margin
Sammanfattning : Mountains evolve and grow because of the large forces that occur from the collision of tectonic plates. Plate boundaries change and move through time, and regions that were once stable, shallow-marine environments can be dragged into subduction zones and get transformed into vast mountain ranges.

4. Crustal architecture of the Kiruna mining district : Structural framework, geological modeling, and physical rock property distribution
Sammanfattning : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. LÄS MER
5. Paleoproterozoic deformation in the Kiruna‑Gällivare area in northern Norrbotten, Sweden : Setting, character, age, and control of iron oxide-apatite deposits
Sammanfattning : This thesis covers the structural evolution of the Kiruna‑Gällivare area in the northern Norrbotten ore province, Sweden. The study area hosts several economically significant iron oxide-apatite (IOA) deposits and includes the type locality for this ore type. LÄS MER
