摘要：

In Quaternary carbonate units composed mostly of eolianites, paleosols are important stratigraphic markers that help differentiate episodes of carbonate deposition tied to glacio-eustatic sea level fluctuations. Paleosols used in this manner can be misinterpreted, and thus lead to errors in interpretation of the geologic record. Some possible pitfalls include: failure to differentiate between terra-rossa paleosols and calcarenite protosols; failure to recognize that separate paleosols may merge laterally into composite paleosols; failure to recognize that single paleosols may bifurcate in highly weathered bedrock; and failure to recognize soil-derived material that infills karst features. The Quaternary carbonates of the Bahamas are used to illustrate these pitfalls, which may occur in carbonates of any age.
