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.[6] The name is derived from para-, the Greek for "near", and laurionite, because of its polymorphic relationship to it.[4] Bright, yellow tips of thorikosite can form on paralaurionite crystals and paralaurionite may also be intergrown with mendipite.[7][8]
Occurrence
It was first described in 1899 for an occurrence in slag in Laurium, Attica, Greece.[3] In 1952 an occurrences of it was reported from the Mammoth Mine, Arizona.[9]
It occurs in lead bearing slag which has been exposed to seawater. It also occurs in polymetallic ore deposits. It occurs associated with laurionite, penfieldite, fiedlerite, phosgenite in slag deposits; and with leadhillite, matlockite, cerussite, hydrocerussite, diaboleite and wherryite in the Mammoth mine location.[3]
