Using the Farmers’ Almanac definition of blue moon (meaning the third full moon in a season of four full moons), the next blue moon won’t occur till May 18, 2019. Generally they are common clear crystals.Well, it’s almost a new year, and depending on your definition, there will either be two blue moons in it, or none. The Columbia Mine in Crittenden County, Halls Gap in Lincoln County, the Lafayette Mine in Crittenden County and at Kings Mountain in Lincoln County are all areas where quartz crystals have been found. There are a quite a few locations where quartz can be found in Kentucky. The mineral fluorite have been found at locations in Kentucky such as the Columbia Mine in Crittenden County, East Faircloth Mine in Woodford County, Danville City in Boyle County, Huston Mine in Livingston County, Lafayette Mine in Crittenden County and Irvington in Breckinridge County. Some other fossils such as bryozoans, corals, pelecypods, conodonts, gastropods, scolecodont teeth, cephalopods, monoplacophorans, crinoids and sponges can also be found in Kentucky in Jefferson, Carroll, Spencer, Nelson and Bullitt Counties. The width of the brachiopod fossils is a little less than two inches on average. Brachiopods are commonly found in the rock formations from the Paleozoic Era. Brachiopods are fossilized shells of marine animals. Carefully searching riverbeds, and exposed benches when water levels are low can be a good way to locate geodes throughout Kentucky.īrachiopod was designated as Kentucky’s official state fossil. Geodes can also be found along the tributaries that form the Green River and the area around the Kentucky River. The creeks present in these formations are the source of numerous geodes. One of the prime locations where geodes are found is at the formations of Warsaw-Salem and the Fort Payne. Geodes are found in abundance in the south central part of Kentucky. The agates are particularly present around exposed areas of the Borden Formation alongside creeks and drainages. The agates in Kentucky can be found in the counties of Jackson, Powell, Estill, Rockcastle and Madison. The organisms continue to add layers of the substance until they are alive resulting in the formation of the pearls.įreshwater pearls can be found in the Tennessee River Valley and the Mississippi River Valley of Kentucky.Īgate was declared as the official state rock of Kentucky. The irritant is mostly sand grains, dirt or a parasite. These organisms release and surround themselves with a substance called nacre often called as mother of pearl in order to get rid of irritants that get accumulated in their shell. Pearls are formed by organisms such as oyster, clam or mussel that live in saltwater or freshwater. In 1986, freshwater pearls were designated as the official state gemstone. Agates, freshwater pearls and fossils are also present in the state. The valley is primarily composed of sedimentary rock resulting only in a few minerals such as fluorite, calcite, quartz, dolomite, geodes and pyrite. Towards the northern border of the state, flows the Ohio River surrounded by the Ohio Valley. Kentucky lies in the southeastern part of the United States.
