The Mid-Atlantic Ridge (MAR) north of the Kane Transform Fault (MARNOK) provides an ideal setting to investigate the interplay between magma supply, faulting, and lithospheric structure at a slow-spreading mid-ocean ridge (MOR). Along this section, two orthogonal segments and four oblique segments bounded by non-transform discontinuities show contrasting accretion styles. Orthogonal segments 1 and 6, located at the southern and northern ends of the study area, show symmetrical spreading, and progressive thinning of the crust with decreasing distance to the axis (from 8-9 km in ~1.12-Myr old lithosphere to 6-7 km on-axis). These segments also display closely spaced, elongated normal faults, and their Mantle Bouguer anomaly (MBA) and Residual Mantle Bouguer anomaly (RMBA) are lower than that of the adjacent oblique segments. The lack of axial volcanic ridges in segments 1 and 6 along with the decreasing crustal thickness towards the axis indicate a reduction in melt supply in recent geological time, and possible fluctuations of the magma supply on characteristic time scales of ~1.12 Myr in this part of the MAR. The oblique segments (Segments 2 to 5) show a mixed tectono-magmatic regime that reflects the structural complexity of the MARNOK region. Detachment faults at the inside corners of segments 2 and 5 along with thin crust indicate earlier asymmetrical, low-magma accretion typical of oblique MAR segments. Present-day magmatism forms discontinuous, sigmoidal, and locally focused axial volcanic ridges that resemble those observed on other oblique MOR segments such as Mohns ridge, and certain oblique areas of the Southwest Indian Ridge. Short, widely spaced faults and irregular volcanic constructions indicate that magma is currently contributing to plate separation. Even though the axial volcanic ridges are aligned with the strike of orthogonal segments 1 and 6, the melt budget of segments 2–5 does not appear sufficient to reorganize these segments into orthogonal spreading. Petrological observations reveal that melt–rock interaction is pronounced in tectonically dominated MARNOK domains. This result along with structural and gravity, observations indicating transient, localized melt focusing occurs within the MARNOK mantle. These findings support observations from other slow and ultraslow ridges showing that magmatic accretion is highly variable and controlled by mantle fertility, detachment-related cooling, and intermittent melt supply. Overall, the results indicate that crustal formation in the MARNOK region is shaped not simply by spreading rate, but by the combined influence of obliquity, melt availability, faulting, and thermal structure. This integrated tectono-magmatic framework provides new insight into how slow-spreading lithosphere evolves north of the Kane Transform Fault and highlights the rapid temporal and spatial variability that characterizes magmatic and tectonic processes at the Mid-Atlantic Ridge.
