抄録

Bakerite has been found as a vein-forming mineral in crystalline limestone near gehlenite-spurrite skarns at Fuka, Okayama Prefecture. The wet chemical analysis, EPMA, and IMA of the mineral yield an empirical formula Ca_8.036B_9.963Si_6.033O_30.092(OH)_9.908 on the basis of O=40. The present data supports the chemical formula calculated by Palache et al. (1951) rather than that for natural specimens given by Giles (1903); Kramer and Allen (1956); Baysal and Dilekoz (1975). The DTA and TG curves, and IR spectrum are also measured. The optical and X-ray diffraction properties agree with previous data.<BR>Bakerite from Fuka may be primarily formed under a low temperature hydrothermal condition.
