The red, elongated solid inclusions were also the most interesting internal features and could be observed in almost every specimen analyzed (figure 11). The crystals’ near-colorless zones were permeated by a series of fibrous red inclusions, approximately oriented from the different crystal faces toward the colored core, in which they gradually disappeared. The orientation of the tiny fibers was not crystallographic, but the general distribution of the fibers followed the crystal growth direction (figures 12 and 13). The needles had different lengths, but their diameters were quite consistent. Their microscopic appearance showed a morphology that seemed less angular and fragmented and more straight and continuous than the hematite “beetle leg” inclusions (once believed to be lepidocrocite) reported in the literature (Hyršl and Niedermayr, 2003; Leon-Reina et al., 2011).
