40Ar/39Ar ages and major elements composition of basalts of the Mid-Atlantic Ridge axis

Ages obtained through the 40Ar/39Ar method for basalt samples with the Nautile submersible along the axis of the Mid-Atlantic Ridge south of the Romanche transform fault.

Major elements measurements were performed on the same samples.

For a complete description of the method and discussion of results, please refer to the Grenet et al. 2023 article.
