Unit cell parameters: Mendipite is colorless to white, brownish cream, grey, yellowish, pink, red, or blue.

Mendipite is found in columnar or fibrous aggregates, often radiated but more rarely straight long fibers, and in cleavable masses.

Cerussite crystallised later, and later still chloride-rich groundwaters reacted with many of these earlier minerals to form more mimetite, as well as blixite, laurionite, mendipite and chlorargyrite.

[7] At the type locality, galena was deposited in Carboniferous Limestone throughout the Mendip Hills during the late Permian or Triassic Period.

[8] The mendipite occurs in nodules in manganese oxide ores, associated with hydrocerussite, cerussite, malachite, pyromorphite, calcite, chloroxiphite, diaboleite and parkinsonite.
