||Eocene limestones can form highly productive aquifers. Some of the limestones are karstic, including in the Diego-Suarez basin. Borehole yields are often tens of litres per second; permeability values of 130 to 860 m/day, and transmissivity values of 725 to 6000 m<sup>2</sup>/day, such as in Majunga town, or in parts of the Morondava basin (in the Western basin) (UN 1988).
