Vladkrivovichevite is a relatively new mineral, approved in 2011 and to date (June 2024) 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).
