Bafflestone is a type of carbonate rock.
The Dunham Classification (Dunham, 1962) of limestones employed the term boundstone to encompass all carbonate rocks that exhibited any evidence of the original components being organically-bound together at the time of deposition. Embry & Klovan (1971Embry, A.F. and Klovan, J.E. (1971) A Late Devonian reef tract on Northeastern Banks Island, NWT. Bull. Can. Pet. Geol., 19, 730–781.) proposed the sub-division of the boundstone classification in order to reflect the different mechanisms of binding within these autochthonous carbonate sediments. The classification ''bafflestone'' was proposed to describe sediments that formed where organic baffling resulted in a reduction in flow and a consequent deposition of suspended material. However, even at the time of introducing the new classification, Embry & Klovan (1971), noted that the class ''bafflestone'' was highly-interpretive and, the mechanism of formation was difficult to prove requiring "''...a good imagination on the part of the geologist''”.

Description
The term "framestone" was not used in the original Dunham classification by Dunham (1962).
It first appeared in the modified Dunham classification by Emb ...
