... was actually observed during the topotactic transformation from tobermorite 11 Å to tobermorite 10 Å. The comparison between structural, X-ray powder diffraction, and micro-Raman spectroscopic data on tobermorite 10 Å and oyelite allows to exclude that oyelite may be the natural counterpart of tobermorite 10...

... * Taylor ( 1964 ) attributed the mineral species tacharanite and oyelite (basal spacing of 12 and 10 Å, respectively) to the tobermorite group. Owing to the lack of structural data, their relationships with the tobermorite group is only speculative. The crystal structure determinations by Merlino...

... of approximately 10 Å. In mineralogical literature, the name “10 Å tobermorite” was used to describe a natural phase occurring at Fuka (Japan) and at Crestmore (USA). However, it was later identified with the mineral oyelite ( Kusachi et al ., 1980 ), a silico-borate with the chemical formula Ca 5 BSi 4 O 14...
