Cryptic striations in the upper mantle revealed by hafnium isotopes in southeast Indian ridge basalts
Article Abstract:
A study that shows mid-ocean ridge basalts from 2,000 km along the southeast Indian ridge display a bimodal hafnium isotopic distribution which reveals the present of ancient compositional striations in the Indian Ocean upper mantle is illustrated. Poisson distribution is anticipated for a well-stirred upper mantle, in which heterogeneity is continually introduced by plate tectonic recycling, and redistribution by viscous stretching and convective refolding.

A younger Moon
Article Abstract:
The tungsten-isotope measurements of lunar rocks by Touboul highlights that the Moon was formed much later and that our knowledge about the early history of the inner Solar System needs to be updated.
