X射线衍射图记录从完全矿化和脱矿部分的皮质骨从牛胫骨。 结果用于获得骨的I型胶原原纤维中分子的平均边到边间距（赤道衍射间距）的量度d。 矿化骨产生的d值为1.23 nm;对于脱矿组织，该值增加至1.52 nm。 因此，似乎骨的矿化将其胶原分子压实在原纤维内。
X-ray diffraction patterns were recorded from fully mineralized and demineralized sections of the cortical bone from cow tibia. The results were used to obtain a measure, d, of the mean side-to-side spacing (equatorial diffraction spacing) of the molecules in the type I collagen fibrils of bone. Mineralized bone yielded a d value of 1.23 nm; for the demineralized tissue this value increased to 1.52 nm. Thus it appears that mineralization of bone compacts its collagen molecules within the fibrils.
