• Cuspidine - Wikipedia

    en.wikipedia.org/wiki/Cuspidine Cuspidine is a fluorine bearing calcium silicate mineral (sorosilicate) with formula: Ca 4 (Si 2 O 7)(F,OH) 2. Cuspidine crystallizes in the monoclinic crystal system and occurs as acicular to spear shaped pale red to light brown crystals. It is a member of the wöhlerite group.. Cuspidine was first described in 1876 for an occurrence in Monte Somma, Italy. The name is from the Greek cuspis ...
