Nasledovite
Nasledovite is an IMA-recognized mineral species in the sulfate class, with the chemical formula PbMn²⁺₃Al₄O₅(SO₄)(CO₃)₄·5H₂O.
It is a member of the Alumohydrocalcite structural group.
Key properties: Mohs hardness 2; specific gravity 3.069; Silky luster; optically biaxial.
IMA symbol Ndv, IMA status: questionable, named in 1958.
A rare fracture filling in oxidized granodiorite porphyry which also hosts polymetallic ores.
It is found associated with Pyrolusite, iron oxide, cerussite.
The mineral was named to honor Professor Boris Nikolaevich Nasledov (1885–1942), geologist, for his investigations of the mineral resources of the Chatkal-Kuramin region, Kyrgyzstan-Uzbekistan.
