It is also considered one of the most important hotspot tracks because the Tristan Hotspot is one of few primary or deep mantle hotspots. |
|
Seamounts are made by extrusion of lavas piped upward in stages from sources within the Earth's mantle to vents on the seafloor. |
|
In both oceanic crust and ophiolites, the gabbro layer is underlain by the mantle, which extends thousands of kilometers down to Earth's core. |
|
During the first stage the volcano erupts basalt of various types, caused by various degrees of mantle melting. |
|
A single, stalked labiate process occurs on the valve mantle, opening as a simple pore on the outer valve surface. |
|
Shell closing limits exposure of the mantle to light, hence autotrophy will be limited. |
|
In mixed borders, soften roses with airy specimens such as catmint or lavender or mix it up with lady's mantle and geraniums. |
|
Alchemilla, known as lady's mantle, is a lovely green plant with small hairs on its leaves. |
|
The key weight-loss ingredients in Pro Clinical Hydroxycut are lady's mantle extract, wild olive extract, komijn extract, and wild mint extract. |
|
Lady's mantle is displaying its yellow to chartreuse flowers held above the foliage now. |
|
Accretion occurs as mantle is added to the growing edges of a tectonic plate, usually associated with seafloor spreading. |
|
|
Gabbro forms from molten rock, called magma, that rises out of the mantle and hardens deep within the crust. |
|
As slab rollback velocities increase, circular mantle flow velocities also increase, accelerating extension rates. |
|
Slab rollback induces mantle return flow, which causes extension from the shear stresses at the base of the overriding plate. |
|
Interactions with the mantle discontinuities play a significant role in slab rollback. |
|
Results demonstrate high temperature anomalies within the mantle suggesting subducted material is present in the mantle. |
|
These form where fluids released from the downgoing plate percolate upwards and interact with cold mantle lithosphere of the forearc. |
|
Compared with the Brown's Creek mantle, a large component of saprolitic material can be identified mixed with the aeolian silt and clay. |
|
The geochemical evidence for a mantle plume origin and the selective crustal contamination of basaltic magmas. |
|
According to their theory, the breakup of continents is directly linked with mantle plumes. |
|
By 1947 he was deemed ready by his brother to take over the mantle but lost the world final to the Scotsman Walter Donaldson. |
|
The buoyant fluids then rise into the asthenosphere, where they lower the melting temperature of the mantle and cause partial melting. |
|
The volcanic arc is the surface expression of the magma that is generated by hydrous melting of the mantle above the downgoing slab. |
|
In addition, mantle plumes may heat the lithosphere and cause prodigious igneous activity. |
|
The very thin lithosphere beneath the rift allows the upwelling mantle to melt by decompression. |
|
Different kinds of transitional crust form, depending on how fast rifting occurs and how hot the underlying mantle was at the time of rifting. |
|
The resisisting force from the surrounding mantle opposes the slab pull forces. |
|
Paradoxically, geochemical analyses of basalts near the FTFZ instead suggest an enriched mantle source and the presence of a mantle hotspot. |
|
Many geoscientists suspect that the plume feeding Hawaiian volcanoes comes from the deepest part of the mantle. |
|
None of the glass in these xenoliths can be directly related to metasomatism or any other process that occurred in situ in the mantle. |
|
He stormed into the house holding a handful of buttonweeds, grabbed the vase, shoved the weeds into it, and placed it on the fireplace mantle. |
