M. Zhizhin et al., SYNTACTIC RECOGNITION OF MAGNETIC-ANOMALIES ALONG THE MID-ATLANTIC RIDGE, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 325(12), 1997, pp. 983-990
Identification of magnetic anomalies for the reconstruction of isochro
ns along oceanic ridges is based on matching similar structural elemen
ts (peaks and troughs) of modeled and observed magnetic profiles acros
s the ridge axis. A method of non-linear alignment of profiles is deve
loped for automating identification of the magnetic anomalies. For the
magnetic data grid from a high-resolution survey SARA (Segmentation A
ncienne de la Ride Atlantique), application of our method to all the p
rofiles forming the rows of the grid allows dating of the crust on the
flanks of the Mid-Atlantic Ridge between 28 degrees and 29 degrees N
to the age of approximately 10 Ma.
