Scanning electron microscopy (SEM) reveals that fine filaments, characteristic of microorganisms, are affiliated with the secondary phosphate mineralization. Constant degradation and fragmentation on the stromatolitic mat has created pellets, peloids, and intraclasts all enriched in secondary apatite. Degrading recrystallization throughout the edges of the first apatite crystals has p... https://michaels111vne2.bmswiki.com/user
