Competing effects of spreading rate, crystal fractionation and source variability on Fe isotope systematics in mid-ocean ridge lavas [PDF]
Scientific Reports, 2021 Two-thirds of the Earth is covered by mid-ocean ridge basalts, which form along a network of divergent plate margins. Basalts along these margins display a chemical diversity, which is consequent to a complex interplay of partial mantle melting in the ...

The Mantle Fe3+/ΣFe Ratio Has Doubled Since the Early Archean [PDF]
Nature CommunicationsHow mantle redox state developed, particularly the mantle source associated with mid-ocean ridge-like settings, remains a subject of ongoing debate. Here, we employ thermodynamic-thermomechanical numerical simulations to explore the redox properties of ...

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Dense melt residues drive mid-ocean-ridge “hotspots” [PDF]
, 2022 The geodynamic origin of melting anomalies found at the surface, often referred to as “hotspots,” is classically attributed to a mantle plume process.

Moytirra: Discovery of the first known deep-sea hydrothermal vent field on the slow-spreading Mid-Atlantic Ridge north of the Azores [PDF]
, 2013 Geological, biological, morphological, and hydrochemical data are presented for the newly discovered Moytirra vent field at 45oN. This is the only high temperature hydrothermal vent known between the Azores and Iceland, in the North Atlantic and is ...

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]
, 2006 During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

Contemporary Physics, 2016 The Earth’s mid-ocean ridges form a single, connected, topological feature which, as Roger Searle points out, is the longest mountain range in the world. They have developed as a result of the sea floor spreading associated with tectonic movements.

Eos, Transactions American Geophysical Union, 2013 The global mid-ocean ridge system is a primary focus for energy transfer from the Earth's interior to the lithosphere, biosphere, hydrosphere, and atmosphere. In a coordinated effort to understand the causes and predict the consequences of mantle-driven physical, chemical, and biological fluxes through the ridge-crest system, the RIDGE (Ridge Inter ...
