Our results show that KIc* influences the type of intrusion formed (dyke, sill or hybrid), and the magnitude of KIcInt impacted the growth rate of the sills. KIcInt was determined during setup of the experiment by controlling the temperature of the upper layer Tm when it was poured into place, with Tm < 24 °C resulting in an interface with relatively low fracture toughness that is favourable for sill or dyke-sill hybrid formation. The experiments help to explain the dominance of dykes and sills in the rock record, compared to intermediate hybrid structures.]]> Wed 11 Apr 2018 16:07:31 AEST ]]> Brittle deformation relating to the Carboniferous-Cretaceous evolution of the Lambert Graben, East Antarctica: a precursor for Cenozoic relief development in an intraplate and glaciated region https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7031 Sat 24 Mar 2018 08:37:56 AEDT ]]> Trench-parallel shortening in the forearc caused by subduction along a seaward-concave plate boundary: insights from analogue modelling experiments https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:18792 Sat 24 Mar 2018 07:51:03 AEDT ]]> Rheological benchmark of silicone oils used for analog modeling of short- and long-term lithospheric deformation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26137 Sat 24 Mar 2018 07:35:29 AEDT ]]> Slab breakoff: insights from 3D thermo-mechanical analogue modelling experiments https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29556 Sat 24 Mar 2018 07:33:12 AEDT ]]> 3D numerical analysis of crack propagation of heterogeneous notched rock under uniaxial tension https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:25475 Sat 24 Mar 2018 07:31:57 AEDT ]]> Three-dimensional inversion modelling of a Neoproterozoic basin in the southern Prince Charles Mountains, East Antarctica https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:4765 Sat 24 Mar 2018 07:20:43 AEDT ]]> A review of tectonics and sedimentation in a forearc setting: Hellenic Thrace Basin, North Aegean Sea and Northern Greece https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24561 Sat 24 Mar 2018 07:11:31 AEDT ]]> Gondwanan basement terranes of the Variscan-Appalachian orogen: Baltican, Saharan and West African hafnium isotopic fingerprints in Avalonia, Iberia and the Armorican Terranes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:24719 Sat 24 Mar 2018 07:11:04 AEDT ]]> Palaeomagnetism of the Dundas-Fossey Trough, Tasmania: Oroclinal rotation and Late Cretaceous overprinting https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43553 Fri 23 Sep 2022 10:19:21 AEST ]]>
