According to Ellon's calculations, the narrow strip underneath the mid-ocean ridge
where hot rock wells up to generate the Juan de Fuca Plate, has attenuation levels that are as high as researchers have seen anywhere on the planet.
Ridge push: Hot buoyant mantle lifts and pushes the plates apart at mid-ocean ridges
where magma solidifies to form new oceanic lithosphere.
Oceanic plates are continuously forged at mid-ocean ridges
, undersea mountain chains created where the edges of two plates are separating.
The compositions of mid-ocean ridge
basalt and seawater used in the numerical model are listed in Table 1.
The range of Fe isotope compositions ([delta][sup.56]Fe) of hydrothermal fluids along modern seafloor mid-ocean ridge
is from -1.26[per thousand] to -0.14[per thousand] with an average value of - 0.52 [+ or -] 0.28[per thousand] (n = 69) (Figure 1).
These topographic alignments are approximately parallel to the ridge segments and to the pseudofaults, showing that their origin took place at the axis of the mid-ocean ridge
The seafloor of the northeastern Pacific Ocean is typical of most oceanic regions in that it features three different kinds of volcanic edifices that produce primarily basaltic volcanic rocks and their intrusive equivalents: mid-ocean ridges
, where new oceanic crust is produced; near-ridge seamounts, which form adjacent to mid-ocean ridges
but are not part of the mid-ocean ridge
system itself; and intraplate seamounts that form well away from plate boundaries, such as the Hawaii-Emperor seamount chain (Fig.
By diving beneath they can navigate 3D sea floor terrain including the Mid-Ocean Ridge
, the world's longest underwater mountain range which stretches 50,000 km around the globe.
Most hydrothermal vents sit on top of the mid-ocean ridge
, the longest continuous mountain range on the planet.
Hydrothermal circulation through mid-ocean ridge
flanks: fluxes of heat and magnesium.
The majority of the planet's hydrothermal systems lies undersea along the mid-ocean ridge
The global mid-ocean ridge
is an immense submarine mountain chain which virtually encircles the Earth.
