    This mineral directly occurs at 1 locality (2 localities according to mindat, 6 localities if parents are counted as well)
    Of the 1 locality at which this mineral occurs, 1 has an age. (6 of the 6 parent localities have ages)


    MDThe mineral occurs at this locality according to MED, but does not have an age yet.
    MDThe mineral occurs at this locality according to MED, and has an age.
    The mineral occurs at some child of this locality.
    The locality at which the mineral occurs does not have an age...this is the closest parent locality with an age, relative to that mineral. This is not ideal.

    AThis mineral is Anthropogenic.
    GThis mineral is directly dated.
    BThis mineral is reported as having this age.
    YThis mineral is using an age reported as an element mineralization period.
    OThis mineral is using an age calculated from all data at the locality.
    RThe age displayed for this mineral originates from a different, non-child locality.
    PThe age displayed for this mineral is the range of ages for this mineral at all of this locality's children.
    This mineral's age has not yet been recorded.
