Unité de Gisement / Unity of Deposit

The title concept "unity of deposit" has to do in international law with the problem of mineral deposits and fields straddling international boundaries on lands and submerged lands, and occuring on, in or under the ground, irrespective of chemical or physical state.

With the same meaning, we can use "unité de gisement" in french, "Vorkommeneinheit" in german, "unidad de yacimiento" in spanish, and "unità di giacimenti" in italian languages.
