Classification of KhangalasiteHide

Notes:
Rejected by the IMA
Approval History:
NOTE: The pre-print version of the Newsletter 48 (IMA CNMNC list of the new mineral proposals approved in February 2019) incorrectly reports the approval of the phase. Contrary to what has been indicated, the proposal has not been approved and therefore both the name and the mineral must not be included among the approved mineral species.
The name and the entire card will be removed from the final version of Newsletter 48 which will be published both in the Mineralogical Magazine and in the European Journal or Mineralogy.
