Stonehenge Formation
The Knox Supergroup, also known as the Knox Group and the Knox Formation, is a widespread Group (geology), geologic group in the Southeastern United States. The age is from the Cambrian, Late Cambrian to the Ordovician, Early Ordovician. Predominantly, it is composed of Carbonate rock, carbonates, chiefly Dolomite (rock), dolomite, with some limestone. There are also cherty inclusions as well as thin beds of sandstone. Stratigraphy The Knox lies beneath a unconformity known as the Knox Unconformity. There is well-developed Karst, karst topography at the top of the Knox Supergroup. This demonstrates a prolonged period of erosion. This has modern economic impact because of forming reservoirs for hydrocarbons as well as some mineral deposits. Everton Formation The Everton Formation is a Formation (geology), geologic formation in northern Arkansas through Missouri, Illinois and Indiana that dates to the middle Ordovician Geological period, Period. It was named by Ulrich (1907) ...

Sphalerite
Sphalerite is a sulfide mineral with the chemical formula . It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in Sedimentary exhalative deposits, sedimentary exhalative, Carbonate-hosted lead-zinc ore deposits, Mississippi-Valley type, and Volcanogenic massive sulfide ore deposit, volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite (and other sulfide mineral, sulfides), calcite, dolomite (mineral), dolomite, quartz, rhodochrosite, and fluorite. German geologist Ernst Friedrich Glocker discovered sphalerite in 1847, naming it based on the Greek word ''sphaleros'', meaning "deceiving", due to the difficulty of identifying the mineral. In addition to zinc, sphalerite is an ore of cadmium, gallium, germanium, and indium. Miners have been known to refer to sphalerite as ''zinc blende'', ''black-jack'', and ''ruby blende''. Marmatite is an opaque black variety with a high iron ...

Stonehenge Dolomite
Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones, held in place with mortise and tenon joints, a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds). Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 BC. The famous circle of large sarsen stones were placed between 2600 BC and 24 ...
