a Si-R2+ graphic of detrital, newly formed and non determined (ND) chlorite compositions. End-members compositions of Vidal et al. (2001) and Inoue et al. (2009) have also been reported. Sud sudoïte, Am amesite, Daph daphnite, Clin clinochlore, TK Tschermak substitution, DT di/trioctahedral substitution. b Fe + Mg-AlVI graphic of detrital, newly formed and non-determined (ND) chlorite compositions. This graphic shows the chemical variations of chlorite due to the DT di/trioctahedral substitution and Tschermak substitution
