Specimen: 2014-003
This specimen is a fossiliferous limestone. The limestone is loosely grain supported, suggesting lithification prior to compaction. The cement matrix is sparite, much of it originating as syntaxial overgrowth. Allochems comprise approximately 70 percent of slide area. These criteria define the limestone as a grainstone. Allochem composition is about 60 percent ooid, 10 percent peloid and 30 percent bioclast. These estimates and degree of sorting characterize the limestone as an unsorted oosparite. Most of the ooids have only faintly visible concentric laminae. Ooid and peloids have similar size ranges with a maximum of .85 mm and minimum of .15. The modal range for ooids/peloids is .25 to .45 mm. The maximum dimension of identifiable bioclasts is as follows: echinoderms 1 mm, bryozoan 4.5 mm, foraminifera .8 mm, and brachiopods 2.5 mm. Micritic envelopes are present on many bioclasts. Extant void space is essentially absent with only a few interparticle examples with a maximum dimension near .2 mm. There are a variety of sparite filled pores including mouldic and shelter (bivalve) forms.
