This Limestone and Dolomite Resources of Kentucky website is a compilation of information about the occurrence and character of quarried carbonate stone resources in the state. It is the culmination of over 65 years of field examination, sampling and analysis by KGS geologists of rock units available for economic development. The sites shown on this map represent quarries, mines, outcrops, and cores that expose carbonate units of interest. Many of the sites were visited by geologists to characterize the stratigraphy of the rock and to take samples for a variety of tests. Other sites show evidence of historical mining, but were not sampled or described.

This website does not contain information on limestone reserves, production, or the current status of limestone operations. For information about limestone production, see the U.S. Geological Survey’s Minerals Yearbook Volume II. For information about the current status of operations that provide materials to the Kentucky Transportation Cabinet, see the KYTC Aggregate Source Book.

The overall goal of this research program was to discern relationships between carbonate lithologies, stratigraphic units, and properties such as chemistry and rock porosity. Much of the raw data collected at the sites is contained in archived field notes available on the website. Chemical analyses for major element oxides (Ca, Mg, Al, Fe, and Si) for over 15,000 samples are available in tabular format and search tools for finding sites having particular thresholds of these constituents are provided.

The data from some of the sites have been previously published and links to online versions of the reports are shown for those localities. A subset of the operations have provided limestone aggregate to the Kentucky Transportation Cabinet at some time and may appear in the Aggregate Source Book published annually by the Cabinet. Summary information from the KYTC is also provided at this website.

A portion of the work to preserve and digitize this limestone and dolomite resource data, including scanning field notebooks and compiling the chemistry database, was supported by the USGS National Geological and Geophysical Data Preservation Program.
This website is very simple to use. The initial view shows all the limestone aggregate sites symbolized by site type and the colored areas represent different limestone units. Tools for navigating the site and getting more information are on the left.

Use the search box to search for a limestone site with either a three letter site code (e.g. BTQ or CBC), site name, or site ID number; or enter a placename or address. Pick a specific type of data to search by using the pulldown on the left to select a search category. The search will prioritize in the order displayed: Limestone Site Name → Limestone Sample Site Code → Limestone Lithology → Geographic Name or Address.
