A usually rounded or columnar sedimentary structure consisting of alternating layers of carbonate or silicate sediment and fossilized microbial mats, produced over geologic time by the trapping, binding, or precipitating of minerals by groups of microorganisms, primarily cyanobacteria.

[Late Latin strōma, strōmat-, covering; see stroma + -lite.]

(Palaeontology) a rocky mass consisting of layers of calcareous material and sediment formed by the prolific growth of cyanobacteria: such structures date back to Precambrian times
