Formula: [Pb32O18][Pb4Mn2O]Cl14(BO3)8.2H2O
Lead oxychloride (oxychorides have both oxygen and chlorine atoms attached to lead atoms in a single molecule; other
components may also be present), manganese- and
boron- bearing mineral
Crystal System: Orthorhombic
Specific gravity: 7.40 calculated
Streak: White
Colour: Pale greenish yellow
Environments
Vladkrivovichevite was approved in 2011 but to date (November 2025) it has been reported only from the type
locality.
Localities
At the type locality, the Kombat Mine, Kombat, Otavi Constituency, Otjozondjupa Region, Namibia, two new (in 2011) lead oxychloride
minerals, hereroite and vladkrivovichevite, occur in association with
asisite, damaraite,
kombatite, sahlinite,
copper, quartz,
barysilite, manganese silicates and a number
of manganese oxyhydroxide minerals on a specimen from the mine. The minerals formed as
late-stage products of hydrothermal reworking of primary sulphide minerals.
Vladkrivovichevite is pale greenish yellow, with a white streak and adamantine lustre
(MM 76.4.883–890).
