(A) Illite crystals occupying small pores in varying directions. (B) Illite within the compact bone region and the corresponding EDS map. (C) Illite within the cancellous bone region and corresponding EDS map. There was a wider distribution of highly concentrated illite in the trabeculae struts. A = apatite, C = calcite, I = illite.
