stromatolith1916

1916 W. G. Foye in Jrnl. Geol. (Chicago) 24 791 The noun ‘Stromatolith’ may be defined as a rock mass consisting of many alternating layers of igneous and sedimentary rocks in sill relationship.

1918 Jrnl. Geol. (Chicago) 26 608 The stromatoliths are the sedimentary equivalent of the calcareous and siliceous ‘sinter’ of the hot springs.

1933 Q. Jrnl. Geol. Soc. 89 415 These bodies—stromatoliths—are composed of chlorite or chlorite with zones of a brown or green-brown isotropic mineral.

1963 D. W. Humphries & E. E. Humphries tr. H. Termier & G. Termier Erosion & Sedimentation xi. 223 The Cyanophyceae can give rise to carbonaceous substances (bogheads) in the form of ‘waterblooms’ and can also precipitate calcareous ‘biscuits’, stromatoliths and calcareous muds.
