This specimen is a fossiliferous limestone. The limestone is loosely grain supported, suggesting lithification prior to compaction. The cementing matrix is sparite, much of it originating as syntaxial overgrowth. Allochems comprise approximately 90 percent of slide area. These criteria define the limestone as a grainstone. Allochem composition is about 65 percent bioclasts, 20 percent intraclasts, and 15 percent peloids, which are possibly intraclasts with no internal structure. These estimates and degree of sorting characterize the limestone as a sorted biosparite. Intraclasts are mostly 3 mm and smaller. Identifiable bioclasts are predominantly micritic walled foraminifera and echinoderms parts. Bryozoan, bivalves, coral, and univalve-mollusk, are also present. Micritic envelopes are uniformly present on foraminifera but variable on other bioclasts. Maximum foraminifera dimension is 1.25 mm and modal size is about .6 to .8 mm. Maximum dimensions of other bioclasts are as follows: echinoderm is 3.5 mm, bryozoan 7.5 mm, univalve-mollusk 1.4 mm, coral 8.5 mm, and bivalve 3.3 mm. Complete bivalve cross-sections are common. Approximately 5 to 10 percent of slide area is composed of extant interparticle voids. Some intraparticle voids are also found within preserved shell cavities. Many of these contain euhedral and compromise boundaries. This reflects calcite crystals growing into these spaces in a drusy mosaic. Authigenic quartz is present in the intraclasts in very small amounts in crystals .1 mm and smaller. Secondary, quartz is rarely present as a replacement mineral in bioclasts.
