    After much debate in the literature, a new chemical formula is proposed that differs from the original H₆Na₂Ca₃Al₄F₅B₆O₂₀:
    Moore P B, Araki T (1972) Johachidolite, CaAl[B3O7], a borate with very dense atomic structure. Nature Physical Science 240, 63-65
    
    The mineral species is formally redefined:
