Which one of the following lithology is most likely being a permeability barrier o a. clean sandstone o b. shale c, fractured limestone d. diatomite

it will be Shale

Explanation:

Because a rock that acts as a barrier to water is a permeability barrier. This cannot be a porous rock such as a clean sandstone, or diatomite (both porous). A fractured limestone will allow solutions to pass through it either along fractures or by dissolving the limestone. A shale is made up of fine clay particles that are tightly packed together and therefore impermeable.
