[Display omitted] •Cyclicicites of biogenic minerals were identified by Raman spectroscopy.•Primary accumulation and diagenetic transformation of Mn were microbially mediated.•Decomposition of cells and EPS contributed to the formation of accessory minerals. There is an increasing consensus that mic...
