Environments
Localities
At the type locality, the Kovdor Zheleznyi Mine, Kovdor Massif, Murmansk Oblast, Russia, krasnovite occurs as
spherulites, up to 3 mm across, consisting of pale blue fibres, in a
dolomite
carbonatite. Associated minerals include
hydrotalcite-2H,
crandallite,
carbonate-rich fluorapatite and
baryte
(Mindat).
Other magnesium phosphates found at this locality include kovdorskite,
bonshtedtite, girvasite,
strontiowhitlockite,
rimkorolgite, juonniite,
gladiusite, collinsite,
barićite and bobierrite
(CM 38.831-838).
The barium incorporated into krasnovite is extracted from carbonates
(CM 44.117-123).
