Mineharu OSHIMA῍,῍῍ and Minoru YOSHIDA῍,῍῍῍Fluorine and chlorine have been determined for +1 GSJ rock reference samples, “Igneous rock series” bytrimethylsilylating distillationion-selective electrode method and by improved HgSCN photometric method,respectively. The results mostly agree with “recommended values” in +33. compilation by GSJ. Some +33.
“preferable values” need further examination. Five data of Cl, which were not presented in +33. compilation, aregiven. Water-soluble chlorine contents in these samples are also determined.
