In a recent study using palaeogeographic reconstructions and palaeo-oceanographic modelling, Ali and Huber (2010) concluded that strong surface currents flowed from north-east Mozambique and Tanzania eastwards towards Madagascar during the Palaeogene, and concord perfectly with conditions favourable for "sweepstake" dispersal of founder individuals from continental Africa.
This problem has been recently re-examined by Ali and Huber (2010), who show that during the Palaeogene and through the Oligocene, Madagascar lay south of the Equatorial Gyre and that strong surface currents then flowed from northeast Mozambique and Tanzania towards the north coast of Madagascar and on eastwards.
The zeolitic material used was a Clinoptilolite-rich tuff that was obtained from the Palaeogene zeoliterich tuffs of the Evros area, North-Eastern Greece.

Samples were collected from formations of Cambrian, Ordovician, Cretaceous, Palaeogene, and Neogene age over a large area in the Baltic, representing more than 2 km difference in (palaeo-) burial depth of the Palaeozoic rocks.
