[Geoinfo] Re: sorry, no nappe, PhD student scholarship in Mainz

[Victor Hugo Garcia]

> PhD student scholarship (3 years) in Sinter studies of Roman aqueducts
> as a data source for palaeoclimate, neotectonics and human culture at
> the Tectonophysics Institute in Mainz, Germany under the supervision
> of Cees W. Passchier.

> which once fed the baths and fountains of the Roman Empire, some up to
> 500 km long, with bridges and inverted siphons crossing valleys, and
> tunnels of up to 95 km long. Since aqueducts were commonly fed from
