Abstract Scope |
The information of lattice-preferred orientation (LPO) of minerals is important to understand the structural anisotropy in earth science, e.g. the relationship between the LPO of olivine and the deformation geometry of Earth’s upper mantle from seismic anisotropy. Non-destructive imaging of minerals using X-ray combining absorption and diffraction contrast tomography provides rich information in resolving the phases as well as mapping out the orientation and morphology of grains non-destructively in 3D.
In the present work, we present a multimodal imaging study of a peridotite sample, using both absorption contrast tomography and diffraction contrast tomography on a laboratory X-ray microscope, for a correlative characterisation of between the LPOs of olivine/pyroxene grains and the natural cracks present in the sample. The advantages of non-destructive 3D crystallographic imaging of minerals will be presented and its future applications for geoscience will be discussed. |
