“This is a rich specimen for the size with numerous off-white, platy crystals standing up on matrix. Surely there are other species present as well, in this complex assemblage known for its rarities. However, the lanarkite is, unusually, very clear and dominant. Type locality material, now hard to obtain. Ex. John White Collection. ”
