Rocks are classified in order to communicate information about them.All classifications of limestones are arbitrary and they frequently overlap or do not fit ones particular needs. Since binocular microscopes or hand lenses are the tools that are commonly available to the explorationist, a practical classification should be based on descriptions using them.

Curdsville Limestone Member.--The Curdsville Limestone Member, the basal member of the Lexington, consists of 20 to 40 ft of bioclastic calcarenite, which is sandy and chert-bearing in part; silicified fossils are common. Near the top of the member, the limestone becomes irregularly bedded, finer grained, and more fossiliferous.
dolarenite or arenaceous calcarenite. Photographs of the four major types of limestone using the Grabau classification are shown below in Figures 3 and 4. Because this classification includes texture in the form of grain size, the textural part of a description may no longer be necessary (see descriptions in Figure 1). Figure 3.
