Aquicluden

Aquicluden is a coined term used in hydrogeology and speculative literature to describe an ideal impermeable layer that prevents groundwater flow, effectively serving as a perfect aquiclude in theoretical models. It is not part of the standard vocabulary in professional practice, where aquiclude and aquitard are used to categorize layers by impermeability.

Aquicluden derives from aqua- meaning water and cludere meaning to close, with the suffix -den used in

In conceptual terms, Aquicluden would exhibit negligible porosity and extremely low permeability, making it an effective

Because it is not a formally defined lithology, Aquicluden has no confirmed occurrences in natural settings.
