Beneath the old continental nuclei are thick root zones which translate coherently during plate motions. These zones are apparently stabilised against convective disruption by the depletion of the continental upper mantle in a basalt-like component. Construction of this delicately balanced tectosphere is accomplished by the dynamic and magmatic processes of the Wilson cycle.

Basalt magma sources during the opening of the North Atlantic
The mantle that supplied basalts to the North Atlantic Tertiary province at the time of continental breakup was isotopically similar to the present-day sub-oceanic mantle. There is no evidence forExpand
Deep Seismic Expression of an Ancient Plate Boundary in Europe
TLDR
The transition to low seismic velocities below Phanerozoic Europe coincides with the crustal boundary zone of the craton and exists to depths of at least 140 kilometers, which rules out any significant lateral transport of asthenospheric material across the suture zone. Expand
Seismic evidence for a fossil mantle plume beneath South America and implications for plate driving forces
A teleseismic travel-time study reveals the presence of a fossil plume in the deep upper mantle beneath Brazil, which has apparently remained geographically fixed with respect to the overly-ingExpand
Section 6. Siderophile Elements in Subcontinental Lithospheric Mantle
Sub-continental lithospheric mantle (SCLM) is interpreted by many to be mantle that began life as DMM, then melted in a plume or subduction zone environment, and finally became emplaced underExpand
The tectosphere and postglacial rebound
Large lateral variations in the thickness of the lithosphere and viscosity of the mantle may be associated with continental roots. The effects of continental roots, or the tectosphere, on postglacialExpand
Geodynamic evidence for a chemically depleted continental tectosphere.
TLDR
Inversions of a large set of geodynamic data related to mantle convection, using tomography-based mantle flow models, indicate that the tectosphere is chemically depleted and relatively cold to 250 kilometers depth below Earth's surface. Expand
Some Speculations on Continental Evolution
There appears to exist a thick (>300 km) thermal boundary layer (TBL), or tectosphere, beneath the ancient cratonic nuclei that is stabilized against convective disruption by a buoyant, viscous,Expand
Subduction zone backarcs, mobile belts, and orogenic heat
Two important problems of continental tectonics may be resolved by recognizing that most subduction zone backarcs have hot, thin, and weak lithospheres over considerable widths. These are (1) theExpand
Seismic Evidence for a Detached Indian Lithospheric Mantle Beneath Tibet.
TLDR
P-to-S converted teleseismic waves recorded across Tibet show a north-dipping interface that begins 50 kilometers north of the Zangbo suture at the depth of the Moho and extends to a depth of 200 kilometers beneath the Bangong suture. Expand
Thermal aspects of komatiite generation and greenstone belt models
Thermal modelling suggests that the problems posed by the high liquid temperatures (∼1,650 °C) of peridotitic lavas in Archaean greenstone belts, and the implied high degree of mantle melting (∼70%),Expand
