Seismic evidence for magmatic underplating along the Kodiak-Bowie Seamount Chain, Gulf of Alaska
2022, TectonophysicsCitation Excerpt :The crust south of the FZ on profile GOA2 is located at Chron 7 (∼24 Ma), while crust north of the FZ is at Chrons 9–10 (∼28 Ma) (Fig. 2b, Walker et al., 2018). Oceanic lithosphere thickness increases linearly with the square root of age up to ∼70 Ma (Davis and Lister, 1974; Stein and Stein, 1992), and thus lithosphere will be thicker for the older crust north of the FZ. Although the predicted lithospheric thickness difference due to age across the FZ will be small (∼8%), it may be sufficient to limit the majority of the magmatic crustal underplating to the younger, southern side of the FZ.

2020, Earth-Science ReviewsCitation Excerpt :The second issue has become evident relatively recently, and this is about the younger part of seafloor (though it also concerns the older part indirectly). As noted above, the simple half-space cooling model yields the subsidence rate of ~355 m Ma−1∕2, and the subsidence of young (<80 Ma) seafloor had been thought to exhibit a similar rate (e.g., 350 m Ma−1∕2 by Davis and Lister (1974) and 345 m Ma−1∕2 by Carlson and Johnson (1994)). This apparent similarity between theory and observation turns out to be coincidental.
