Alimenter la ville de Lyon en eau : les galeries de captage antiques sous les collines de Fourvière et de la Croix-Rousse by Emmanuel Bernot

“…Most of the sedimentary formations forming the Fourvière and Croix-Rousse hills are conducive to water circulation and the aquifer levels are therefore concentrated in contact with impermeable or low-permeability formations, such as basalt and clay. The Croix-Rousse hill, which rises to an altitude of about 250 m NGF, has particularly abundant aquifer resources spread over a height of about 60 m. …”

Accelerated non-linear destruction of the earth's crust by E. V. Artyushkov

“…In most areas, at depths ∼20–40 km the continental crust is composed of basalts with density ∼2900kg m−3. At temperature and pressure typical for this depth, basalts are metastable and should transform into another assemblage of minerals which corresponds to garnet granulites and eclogites with higher densities 3300–3600 kg m−3. …”
