Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
Solbakk, Terje; Fichler, Christine; Wheeler, Walter H; Lauritzen, Stein-Erik; Ringrose, Philip (Journal article; Peer reviewed, 2018)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Geophysical expression of the Leka Ophiolite, Norway modeled from integrated gravity, magnetic and petrophysical data
Michels, Alexander; McEnroe, Suzanne; Fichler, Christine (Journal article; Peer reviewed, 2018)The ca. 497 Ma Leka Ophiolite Complex (LOC) comprises oceanic lithosphere that formed near the margin of Laurentia in a suprasubductionzone setting. The LOC was obducted onto Laurentia in the Early Ordovician and later ... -
Geophysical Mapping and Paleomagnetic Study of the Leka Ophiolite Complex
Michels, Alexander (Doctoral theses at NTNU;2019:32, Doctoral thesis, 2019)This thesis presents the results of a geophysical study of the Leka Ophiolite Complex (LOC) in central Norway, carried out to refine the understanding of the LOC’s sub surface geometry, fault structure and structural ... -
Geophysical mapping of the mafic and ultramafic rocks of the Seiland Igneous Province from the kilometer to the micrometer scale
Pastore, Zeudia (Doctoral theses at NTNU;2018:328, Doctoral thesis, 2018)The Seiland Igneous Province (SIP) is the largest complex of mafic and ultramafic intrusions in northern Norway, and one of the best preserved deep-seated magmatic plumbing systems in the world. The province, generated ... -
Integrated interpretation of seismic and potential field data on the Frøya High, Mid Norway
Birkeland, Jardar (Master thesis, 2016)The mid-Norwegian continental margin has been tectonically active from the Caledonian Orogeny. The main tectonic phases happened during Jurassic-Cretaceous and Cretaceous-Cenozoic time. This thesis will present interpretations ... -
Magnetic anomalies of the mafic/ultramafic seiland igneous province
Pastore, Zeudia; Fichler, Christine; McEnroe, Suzanne (Journal article; Peer reviewed, 2018)The Ediacaran Seiland Igneous Province (SIP) is the largest complex of mafic-ultramafic intrusions in northern Fennoscandia and one of the few examples of a well preserved deep-seated magmatic plumbing system. The major ... -
Magnetic mapping of fault zones in the Leka Ophiolite Complex, Norway
Michels, Alexander Christopher; Fichler, Christine; Pastore, Zeudia; McEnroe, Suzanne (Peer reviewed; Journal article, 2020)The island of Leka and surrounding skerries expose a complete suite of ophiolitic rocks, which are heavily faulted. Large areas consist of ultramafic rocks, which are locally hydrated and form serpentinites. Faults are ... -
Onshore to offshore correlation of ore-forming hydrothermal systems: Geological investigations of the Reinfjord Ultramafic Complex and Southwestern Barents Sea
Ryan, Eric James (Doctoral theses at NTNU;2023:76, Doctoral thesis, 2023)Demand for mineral resources continues to grow, while political pressure, legitimate environmental concerns, and important ethical questions slow the development of new mineral resources. Simultaneously, emerging technologies ... -
Petrology of the crystalline crust in the southwestern Barents Sea inferred from geophysical data
Fichler, Christine; Pastore, Zeudia (Peer reviewed; Journal article, 2022)We present a new petrological model of the crystalline crust in the southwestern Barents Sea derived in a comprehensive workflow that focuses on the interpretation of gravity, magnetic and seismic data and that incorporates ... -
Portrait of a giant deep-seated magmatic conduit system: The Seiland Igneous Province
B. Larsen, Rune; Grant, Thomas; Sørensen, Bjørn Eske; Tegner, Christian; McEnroe, Suzanne; Pastore, Zeudia; Fichler, Christine; Nikolaisen, Even; Grannes, Kim Rune Bragstad; Church, Nathan Stewart; ter Maat, Geertje; Michels, Alexander (Journal article; Peer reviewed, 2018)The Seiland Igneous Province (SIP), Northern Norway, contains > 5000 km2 of mafic and ultramafic intrusions with minor alkaline, carbonatite and felsic rocks that were intruded into the lower continental crust at a depth ... -
The Magnetic Petrological Expression of Slipsteinsberget, a Zoned Serpentinized Ultramafic Body in Trøndelag
Ånestad, Siren (Master thesis, 2020)Slipsteinsberget er et brudd i en sonert serpentinisert ultramafisk kropp nær Sparbu, Trøndelag, Norge. Bruddet befinner seg i det neoproterosoiske til kambriske Skjøt-ningsdekket. Arkeologisk sett har området en lang ...
