Bindstone

Bindstone is a special type of carbonate rock in the Dunham classification.

Embry and Klovan (1971)[1] define bindstones as rocks that "[...] contain in situ, tabular or lamellar fossils which encrusted and bound sediment during deposition.

"[2] Wright (1991)[3] uses bindstone as a synonym for boundstone, which is defined as a rock "[...] where the structure reflects the encrusting and binding action of plants or animals"[4] Lokier and Al Nunaibi (2016)[5] define bindstones as "autochthonous carbonate-dominated rock in which the original components of the supporting matrix were organically bound through stabilization of the sediment at the time of deposition.

For Embry and Klovan (1971), a boundstone is used for autochthonous carbonates if there is a lack of evidence for the more precise classifications as bafflestone, bindstone or framestone.

In contrast to that, Wright (1991) uses boundstone and bindstone synonymously, which is not consistent with other authors.
