Deep seismic reflection profiling is one of the internationally recognized advanced techniques that can reveal the fine structure of continental lithosphere.
Although 20 km value is low in relation to other works, it is totally congruent with the results that have to be expected in Admittance studies, that make use of free air anomalies, because in studies like McKenzie and Fairhead (1997), it has been found that for continental lithosphere the elastic thickness value, with some exceptions, do not exceed 25 km, since, it is usually close to the seismogenic thickness value, this argument is still in discussion.
Imaging, Mapping and Modelling Continental Lithosphere Extension and Breakup
Likewise, until recently, the interrelationship between the buoyant, continental lithosphere and the mantle had been ignored, except in a few older papers.
Mantle nodules brought to the surface by melts show that much of the continental lithosphere has been depleted by melt removal, leaving a harzburgite whose density is substantially greater than that of the fertile mantle.
Most mantle heterogeneity appears related to melt extraction to form continental and oceanic crust, and recycling of oceanic and continental lithosphere back into the mantle.
It's possible that magmatism in this initial phase was a product of residual effect of rifting phase that was developed progressively from the Triassic thinning continental lithosphere and then in the Middle Jurassic it obeyed with more security a derived magmatic arc of a subduction zone (Fig.

The collision tectonics has remobilized the Archean to Proterozoic continental lithosphere in a thick NE-dipping ductile slab-like folded Himalayan Metamorphic Belt (HMB).
There is little question that it has been a successful "big science" project, bringing together earth scientists from across the country to work toward a common goal: to understand the large-scale architecture of the Canadian continental lithosphere.
Continental lithosphere is strongest in midcontinent areas, where it is oldest and therefore coldest.
