Meckley's Quarry, Mandata, Northumberland Co., Pennsylvania, USA

Ref. Mineralogy of PA, 1965-76 , Robert C. Smith, pg 251. Limestone quarry and noted Strontium mineral occurance, in Laminated Tonoloway Limestone, exhibiting evidence of deposition of "tidal flats" origin. Successive layer upon layer of algal mats, trapping calcium-carbonate materials, and abundent mud cracks suggesting periods of solar exposure.

246 acres quarry, first established in 1936 by J. Eugene Meckley producing a high quality acricultural lime (calcium oxide), operating eight "set kilns". In 1946 the business expanded into truck and field spreading and in 1947 included a grinding mill for the production of calcium carbonate, eliminating the need for kiln firing the limestone. By the 1960's the company had expanded to include a fleet of 27 field spreaders.
In 1963 the quarry was granted approval from the Pennsylvania Department of Transportation for use of it's crushed gravel in paving and road construction.
In 1982 the U.S. Department of Energy pursued the use of pulverized limestone as an effective sobent. Using Meckley's limestone in their testing, the material from this quarry proved effective and is now currently used for the capture of sulfur dioxide from power plant emmissions.
Owned and operated by the Meckley family for three consecutive generation, the quarry was sold in 1991 and is in continual operation.

Note: This quarry has been operated an an agricultural and industrial materials quarry, and while some very minor Calcium vein deposits do occur here, it has never been used as decorative stone (i.e. "Travertine") quarry.
