I,too, have found that areas high in limestone, quartz, and granite seem to have a higher occurrence of paranormal activity be it supposed hauntings or other phenomena such as earth-lights. I have done investigations in our area of KY and some have had quite a bit of activity. After researching the limestone theory, I found that the Brandenburg area of Meade County was one of the sites where lithographic Limestone was quarried...here is an article I found about it:
Lithographic limestone is hard limestone that is sufficiently fine-grained, homogeneous and defect free to be used for lithography. Geologists use the term lithographic texture to refer to a grain size under 1/250 mm. The term sub-lithographic is sometimes used for homogeneous fine-grained limestone with a somewhat coarser texture
The generally accepted theory for the origin of lithographic and sub-lithographic limestone is that they were formed in shallow stagnant hyper-saline and anoxic lagoons. The combination of mild hyper-salinity and low oxygen content is believed to have inhibited the formation of microbial mats and prevented the invasion of bottom dwelling organisms. Microbial mats and bottom dwelling organisms would have left fossils, and bottom dwelling organisms would have churned the accumulating sediment, producing a less homogeneous rock. Stagnancy was required to avoid churning or sculpting of the sediment by currents or wave action
The American Lithographic Stone Company was organized in Louisville, Kentucky in late 1868. It initially focused its operation on quarries in Overton County, Tennessee, but shortly before 1900, it opened a quarry at Brandenburg, Kentucky. This quarry was the only commercial source of lithographic stone in the United States at the turn of the 20th century. Unlike the Solnhofen stone, Kentucky lithographic limestone was slightly dolomitic, and it was judged to be competitive with Solnhofen stone for some purposes, but not for the highest quality work. This stone source was sub-Carboniferous (Mississipian). In 1917, the Brandenburg quarry was judged the most important source of Lithographic stone in the United States. Prior to 1916, the output of the Brandenburg quarry was small, but in 1916, as World War I cut off access to Solnhofen stone, the quarry produced 20 tons of finished lithographic stone. The Remains of the Brandenburg Lithograph Quarry are located along the Buttermilk Falls Historic Walking Trail (38°0′3.54″N 86°9′34.74″W / 38.0009833°N 86.15965°W / 38.0009833; -86.15965)
