Paralaurionite is a colorless mineral consisting of a basic lead chloride PbCl(OH) that is dimorphous with laurionite. It is a member of the matlockite group. The name is derived from para- the Greek for near and laurionite because of its polymorphic relationship to it. Bright yellow tips of thorikosite can form on paralaurionite crystals and paralaurionite may also be intergrown with mendipite.
