TS Must-Read – Cannat et al. (2006) Modes of seafloor generation at a melt-poor ultraslow-spreading ridge

For the first time in 2006 Cannat and co-workers described a smooth seafloor type in the mid-ocean ridge located in the SW Indian Ocean (SWIR). The 660-km-long off-axis bathymetry, gravity, and magnetic dataset presented in the study lies near the Rodrigues triple junction (RTJ in Fig. 1). The must read paper expanded the previous conceptual models that considered mid ocean ridges as primarily vol ...[Read More]
