About MianningiteHide

Formula:
(◻,Pb,Ce,Na)(U4+,Mn,U6+)Fe3+2 (Ti,Fe3+)18O38
Colour:
Black
Lustre:
Sub-Metallic
Hardness:
6
Specific Gravity:
4.62
Crystal System:
Trigonal
Name:
Named after the county of its type locality, Mianning county, Sichuan province, China.
Mianningite can be considered as the analogue of mapiquiroite with the M0 site preferentially vacant.
Initially ◻-dominant mineral of davidite group without special name was described from Kazakhstan (Ryzhov e.a., 1983). Then a poorly characterized mineral of the same composition from Romania named Romanite was published without approval (Dragila, 1990).
