Fluid flow due to the advance of basin-scale silica reaction zones (2008)
Journal Article
Davies, R., Goulty, N., & Meadows, D. (2008). Fluid flow due to the advance of basin-scale silica reaction zones. GSA Bulletin, 120(1-2), 195-206. https://doi.org/10.1130/b26099.1

The conversion of biogenic silica (opal-A) to opal-CT (cristobalite and tridymite) in biosiliceous sediment causes increased rates of water expulsion because of the reduction in sediment porosity and dehydration of the amorphous opal-A phase. This re... Read More about Fluid flow due to the advance of basin-scale silica reaction zones.

Differential compaction and subsidence in sedimentary basins due to silica diagenesis: A case study (2005)
Journal Article
Davies, R. (2005). Differential compaction and subsidence in sedimentary basins due to silica diagenesis: A case study. GSA Bulletin, 117(9-10), 1146-1155. https://doi.org/10.1130/b25769.1

The conversion of opal A to opal CT is a thermochemical diagenetic process that can cause kilometer-scale differential compaction and differential subsidence within clastic sedimentary basins. This is demonstrated for an opal A to opal CT conversion... Read More about Differential compaction and subsidence in sedimentary basins due to silica diagenesis: A case study.

Termination of a fossil continent-ocean fracture zone imaged with three-dimensional seismic data: The Chain Fracture Zone, eastern Equatorial Atlantic (2005)
Journal Article
Davies, R., MacLeod, C., Morgan, R., & Briggs, S. (2005). Termination of a fossil continent-ocean fracture zone imaged with three-dimensional seismic data: The Chain Fracture Zone, eastern Equatorial Atlantic. Geology, 33(8), 641-644. https://doi.org/10.1130/g21530.1

We describe the first three-dimensional imaging of the termination of a continent-ocean fracture zone (COFZ), the Chain Fracture Zone, located offshore of the Niger Delta. The COFZ marks the abrupt transition between extended continental crust, compr...

Kilometer-scale fluidization structures formed during early burial of a deep-water slope channel on the Niger Delta (2003)
Journal Article
Davies, R. (2003). Kilometer-scale fluidization structures formed during early burial of a deep-water slope channel on the Niger Delta. Geology, 31(11), 949-952. https://doi.org/10.1130/g19835.1

Three-dimensional seismic data reveal a series of kilometer-wavelength hummocks and intervening depressions that formed above a 22-km-long section of a Pliocene–Pleistocene deep-water slope channel on the western margin of the Niger Delta. The depres... Read More about Kilometer-scale fluidization structures formed during early burial of a deep-water slope channel on the Niger Delta.

Three-dimensional seismic imaging of Paleogene dike-fed submarine volcanoes from the northeast Atlantic margin (2002)
Journal Article
Davies, R., Bell, B., Cartwright, J., & Shoulders, S. (2002). Three-dimensional seismic imaging of Paleogene dike-fed submarine volcanoes from the northeast Atlantic margin. Geology, 30(3), 223-226. https://doi.org/10.1130/0091-7613%282002%29030%3C0223%3Atdsiop%3E2.0.co%3B2

We use three-dimensional seismic data to describe the architecture of shallow intrusive igneous sill and dike complexes intruded into the upper crust as well as the internal and external geometry of extrusive conical igneous mounds that were fed by t...

Early Oligocene initiation of North Atlantic Deep Water formation (2001)
Journal Article
Davies, R., Cartwright, J., Pike, J., & Line, C. (2001). Early Oligocene initiation of North Atlantic Deep Water formation. Nature, 410, 917-920. https://doi.org/10.1038/35073551

Dating the onset of deep-water flow between the Arctic and North Atlantic oceans is critical for modelling climate change in the Northern Hemisphere1, 2 and for explaining changes in global ocean circulation throughout the Cenozoic era3 (from about 6...
