Paralaurionite is a colorless mineral consisting of a basic lead chloride PbCl(OH) that is dimorphous with laurionite.

[6] The name is derived from para-, the Greek for "near", and laurionite, because of its polymorphic relationship to it.

[9] It occurs in lead bearing slag which has been exposed to seawater.

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.
