Mudstone vs. Shales
The primary distinction between shale and mudstone lies in fissility. Mudstone, though composed of similar materials, lacks the distinct layering characteristic of shale. Geologists often attribute this difference to the kinetic energy profile of the settling sediment; mudstones form from sediments settling too slowly to permit particle alignment, whereas shales require a sudden decel… -
