The Mid-Atlantic Ridge near 13º20’N: High-Resolution Magnetic and Bathymetry Imaging (2018)
Journal Article
Searle, R., MacLeod, C., Peirce, C., & Reston, T. (2019). The Mid-Atlantic Ridge near 13º20’N: High-Resolution Magnetic and Bathymetry Imaging. Geochemistry, Geophysics, Geosystems, 20(1), 295-313. https://doi.org/10.1029/2018gc007940

We describe detailed magnetic and bathymetric studies around 13°N on the Mid‐Atlantic Ridge, a site of extensive detachment faulting. Inversion of closely spaced sea surface magnetic anomalies reveals a disorganized pattern of magnetization, with ano...

Construction and subduction of the Louisville Ridge, SW Pacific—insights from wide-angle seismic data modelling (2018)
Journal Article
Robinson, A., Peirce, C., & Funnell, M. (2018). Construction and subduction of the Louisville Ridge, SW Pacific—insights from wide-angle seismic data modelling. Geophysical Journal International, 215(3), 2222-2245. https://doi.org/10.1093/gji/ggy397

The Louisville Ridge is a ca. 4000 km-long chain of seamounts in the SW Pacific that is currently being subducted at the Tonga-Kermadec trench. The Pacific Plate, on which the chain sits, is subducting obliquely beneath the Indo-Australian Plate. Com...

Episodic magmatism and serpentinized mantle exhumation at an ultraslow spreading centre (2018)
Journal Article
Grevemeyer, I., Hayman, N., Peirce, C., Schwardt, M., van Avendonk, H., Dannowski, A., & Papenberg, C. (2018). Episodic magmatism and serpentinized mantle exhumation at an ultraslow spreading centre. Nature Geoscience, 11, 444-448. https://doi.org/10.1038/s41561-018-0124-6

Mid-ocean ridges spreading at ultraslow rates of less than 20 mm yr−1 can exhume serpentinized mantle to the seafloor, or they can produce magmatic crust. However, seismic imaging of ultraslow-spreading centres has not been able to resolve the abunda...
