When present, the amount of marine cement is typically described as significant or extensive, and the rates of cementation are interpreted to have been fast (tens to thousands of years). For example, Perry (35) described cementation as having a “dominant” importance in the preservation of reef frameworks in Jamaica if at least 75–100% of skeletal pores contained cement or sediment, “secondary” if 50–75% of skeletal pores contained cements, and “minor” if <50% were partially filled. We also add the category of “trace” importance if <25% of skeletal pores contained cements. Mean cement abundances for all ETP samples represent trace amounts. See Fig. 3 for locations of reef sites. Data points represent the mean percentage (± SEM) of coral pores with cements by site.
