Specimen: 2014-046
This is a fossiliferous limestone. The limestone is grain supported with a sparite cement matrix. Allochems constitute about 65 percent of slide area. These criteria define the limestone as a grainstone. Allochem composition is about 85 percent peloid and 15 percent bioclast. These estimates and the degree of sorting define the limestone as an unsorted pelsparite. Identifiable bioclast maximum dimensions are as follows: bivalve (not including sinuosity) 2.8 mm, calcispheres .15 mm, echinoderm .6 mm, univalve mollusk .6 mm. Bivalves predominate and are usually completely replaced by secondary sparry calcite. Micritic envelopes are variably present. Peloids have a maximum dimension around .4 mm and a modal size range around .15. The size range of peloids is commensurate with a predominantly faecal origin. Collophane is very rare and has a maximum dimension of .4 mm. Iron hydroxides and opaque grains are present but are less than 1 percent of slide area. Extant voids are mostly absent at far less than 1 percent of slide area, those that are present are mostly interparticle with a maximum dimension near .25 mm. Lithification likely occurred prior to significant compaction, given the relatively will preserved allochems.
