Fractured and polished surfaces revealed an intrinsic structural diversity across the calculi sections. In general, the calculi presented highly mineralized amorphous-looking cores surrounded by concentric alternating mineralized and organic layers. The thickness of these layers decreased from the outer regions toward the center of the sialolith, illustrating a sequence of growth stages. Nevertheless, a significant variability could be detected among the specimens. In some cases, the calculi displayed multiple cores and lacked concentric laminated structures. In other instances, the specimens exhibited extensive regions of globular structures. In these cases, the globule diameter decreased across the radius toward the center of the sialoliths, and the globular structures tended to reorganize, forming bright and dark laminated layers surrounding the core. The participation of globular structures in the layer formation process points to morphogenetic mechanisms not previously described.<\/jats:p>","DOI":"10.1017\/s1431927607070754","type":"journal-article","created":{"date-parts":[[2007,9,28]],"date-time":"2007-09-28T10:39:14Z","timestamp":1190975954000},"page":"390-396","source":"Crossref","is-referenced-by-count":11,"title":["On the Structural Diversity of Sialoliths"],"prefix":"10.1093","volume":"13","author":[{"given":"Ant\u00f3nio P.
