Seismicity trends and detachment fault structure at 13N, Mid-Atlantic Ridge (2020)
Journal Article
Parnell-Turner, R., Sohn, R., Peirce, C., Reston, R., MacLeod, C., Searle, R., & Simao, N. (2021). Seismicity trends and detachment fault structure at 13N, Mid-Atlantic Ridge. Geology, 49(3), 320-324. https://doi.org/10.1130/g48420.1

At slow-spreading ridges, plate separation is commonly partly accommodated by slip on long-lived detachment faults, exposing upper mantle and lower crustal rocks on the seafloor. However, the mechanics of this process, the subsurface structure, and t... Read More about Seismicity trends and detachment fault structure at 13N, Mid-Atlantic Ridge.

Magmatic and tectonic segmentation of the intermediate-spreading Costa Rica Rift - a fine balance between magma supply rate, faulting, and hydrothermal circulation (2020)
Journal Article

3-D tomographic modelling of wide-angle seismic data, recorded at the intermediate-spreading Costa Rica Rift, has revealed a P-wave seismic velocity anomaly low located beneath a small overlapping spreading centre that forms a non-transform discontin...

3-D P-wave velocity structure of oceanic core complexes at 13◦N on the Mid-Atlantic Ridge (2020)
Journal Article
Simão, N., Peirce, C., Funnell, M., Robinson, A., Searle, R., MacLeod, C., & Reston, T. (2020). 3-D P-wave velocity structure of oceanic core complexes at 13◦N on the Mid-Atlantic Ridge. Geophysical Journal International, 221(3), 1555-1579. https://doi.org/10.1093/gji/ggaa093

The Mid-Atlantic Ridge at 13° N is regarded as a type locality for oceanic core complexes (OCCs), as it contains, within ∼70 km along the spreading axis, four that are at different stages of their life cycle. The wealth of existing seabed observation... Read More about 3-D P-wave velocity structure of oceanic core complexes at 13◦N on the Mid-Atlantic Ridge.

Magmatism versus serpentinization – crustal structure along the 13°N segment at the Mid-Atlantic Ridge (2020)
Journal Article

A region of oceanic core complexes (OCCs) exists at 13°N on the Mid-Atlantic Ridge that is regarded as a type site. This site includes two OCCs at 13°20′N and 13°30′N, thought to be in the active and dying stages of evolution, and two together called...
