Some examinations on the quantitative analysis of complex sulfide minerals were carried out by electron probe microanalyser with three methods as follows : (1) The method using metals and simple sulfides as standard samples correcting about the effects of absorption, fluorescence and average atomic number by calibration formula. (2) The method using sulfide mineral as standard sample similar to composition of examining specimen, comparing with both intensities of X-ray radiation of elements in standard and examining samples. (3) The method using the calibration curves shown the relation between intensities of X-ray radiation and contents of elements in several standard samples which consist of same elements as the analysing sample. The results obtained by the method using the calibration curves were best among them mentioned above. Also, wittichenite from the Obari and Naganobori mines, and horobetsuite from the Horobetsu mine were tentatively analysed by using calibration curves as shown in Figs. 3 and 4,and their results were in good accordance with stoichiometric composition Cu_3BiS_3 and that of Bi_2S_3-Sb_2S_3 solid solution respectively as shown in Tables 7 and 8.
