Geochemical control on the evolutionary history of the Ballantrae Complex, SW Scotland, from comparisons with recent analogues
Read more of: Geochemical control on the evolutionary history of the Ballantrae Complex, SW Scotland, from comparisons with recent analoguesA combination of geochemical and field investigations of the Ballantrae Complex allows some control on the relative timing of events in its tectono-magmatic history. In particular, the presence of boninitic […]

An investigation into the nonlinear frequency shift in magnetospherically propagated VLF pulses
Read more of: An investigation into the nonlinear frequency shift in magnetospherically propagated VLF pulsesWhen ducted narrow-band VLF pulses pass through the Earth’s magnetosphere, small frequency shifts of ∼1 Hz may be observed at the receiving site on the ground. Such shifts may be […]
