Research interests synopsis
Involved in research within petrology, structural geology, ore deposits and applied mineralogy. I am currently working on the relation between magmas, volatiles and shearzones in ancient continental rift zones. This involves field work, thermodynamic modelling, microstructure evolution using optical microscopy, EBSD and EPMA. Our recent findings documents the processes behind strain localisation and hence earthquake forming mechanisms below continental rift-zones and their relation to CO₂ emission (Sørensen et al., 2019; Ryan et al., 2022). I am also intrested in improved quality annd use of EBSD data and work on both aquisition in our in-house SEM equiped with NORDIF EBSD detector and software and data interpretation and represenstation using MTEX. As a teacher in optical mineralogy I devoloped an improved Michel Levy chart for determination of interference colour and hence birefringence (Sørensen, 2013). This methodology was expaned to work in 3D crystal space to visualize and quantify the relation between orientation, interference color and extinction in minerals in generalized fashion available in the MTEX toolbox together with Ralf Hielscher and David Mainprice and I am quite proud to part of the MTEX contributors . As an example this can be used to show the realtion between optical properties of olivine and the Fayalite-Forsterite amount and simulate optical images from EBSD data.

EBSD
Involved in the development of the SEM-lab, including our state of the art EBSD equipment. My special focus here is the improovement of indexing and phase discrimination between complicated low symmetry geological materials. We now have an impressive indexing percenttage of quartz abowe 98%. We currently ressearch on crystallographic fabric development in quartz, including the influence of twinning. Because we do offline data interpretation we can return to the original data and check indexing against EBSPs of the indexed points, making sure that we do not filter away correct data during cleanup proceedures (Sørensen et al., 2020). In addition we also developed new trapezoidal correction for multi-mapping, which takes care of the distortion in the EBSD scan by controlling scan voltages such that steps in X and Y are on a square grid. This insures that geometrical features such as grain boundaries are correctly represented in the maps and that stich of coarse grained ebsd datasets works seamlessly (Sørensen et al., 2020).

Data are collected using TSL-OIM sofware and then transferred into MTEX for more advanced analysis. We have exellent analysis facilities and encourage scientiffic colaboration, so feel free to take contact with Bjørn Eske Sørensen (bjorn.sorensen@ntnu.no) on EBSD. MTEX is used for improved interpretation of EBSD data, which contains spatially distributed crystallographic data which contains much more information than can be accessed by convetional commercial software. As an example we used combination of microstrucral information (grain shape) to automatically determine twin/host relationships in calcite and hence separate effects of dislocation creep and eTwin slip on the crystallographic fabric and hence infer important inforamtion about chenges in stress system and deformation mechanisms (Ryan et al., 2021). Another important apllication of the methodology developed is used on quartz where Dauphiné twins creates a mess in the statistics of grain-based pole figure plots, where each twin traditionally is treated as separate grains. Because each grain fo quartz contains numerous twins the twin grains craets a mess in the pole figures which is difficult to interpret. Instead by analysing each twinned grain and assembling automatically into groups of twins and hosts we can plot the average orientaiton of each group and get a much more rigurous interpretation of the data and futhermore a much more statiscally sound grain number i.e. one grain for each twin member and host, see Giuntoli et al., (2022).
Deformation processes and volatile-rock- melt interaction in upper-mid and lower crust
One of my recently most active projects is on the interaction between melt-volatiles and solid rock in the deformation of earth and genration of earthquakes. The Reinfjord intrusion in North Norway provides a unique field laboratory giving us a window into the lower crust (25-40 km depth) of the ultramafic parts of continental extsion zone, an ancient refelction of modern day riftzones like the east african rift. We have already been able to show:
1: That CO₂ induces localized grain size reduction in peridotitte from cm's down to 5 micrometers due volume expanding mineral reactions, causing increase in strain rate by more than two orders of magnitude, finally leading to eartquakes, revealed by fossilized frictional melts (pseudotachylites). (Sørensen et al., 2019; Ryan et al., 2022)
2: CO₂ originates from volatile rich mafic melts dyking the peridotite and the fractional heating caused by the strain localisation remelts the mafic dykes with the melt film causing large stress release due to weakening (Ryan et al., 2022).
3: This process also relates mafic dykes to strain localization along a >2km long extensional shearzone (Ryan et al., 2022).
4: This relation between CO₂ emission, seismicity and mafic volatile rich magma explains the observation of links between earthquakes and large scale CO₂ emissions in present day continental riftzones
