The resulting bathymetric chart is believed to reliably portray the tectonic fabric of the basin and provide insight into the formation of the seafloor and development of associated structural features. The South Pandora Ridge (Hazel Holme Fracture Zone) appears to be a youn

https://doi.org/10.1007/978-3-030-38058-8on Islands suggest that seafloor spreading in the North Fiji Basin, which began in the latest Miocene, continues today. The North Fiji Basin is marked by at least two triple junctions, located in the central (16°50’S, 173°45’E) and northeastern (14°S, 179°30’E) parts of the basin. Both were apparent

Francesca D’Elia,Gaetano Raiolaated, sediment-free areas occurring along the ENE-trending South Pandora Ridge and along a north-trending wedge of ridge and trough terrain that extends northward from the presently active Central North Fiji Basin Ridge (CNFBR) are interpreted as having recently formed, i.e., they are younger than 2

José M. Alonso,Gabriella Casalinostudy is based on a detailed examination of five piston cores that have sampled a continuous sedimentary record of the last 0.8 m.y. Three cores are from the sediment-covered, abyssal hill terrain in the central part of the Basin and two are from an archipelagic apron (New Hebrides apron), which ext

There is no significant compaction of sediments, and lithification has occurred as a response to period

Mária Slavíčková,Michaela Vargová lavas from three sites including one dredge of abyssal ferrobasalt are low-Kmid-ocean ridge basalt (MORB) similar to those of mid-ocean spreading centers, but with slightly higher .Sr/.Sr = 0.7034. Lavas from two sites are slightly enriched in K, Rb, Zr, Ba, and possibly water, relative to normal M
