Limestone in the context of "Matera"

The Giza pyramid complex (also called the Giza necropolis) in Egypt is home to the Great Pyramid, the pyramid of Khafre, and the pyramid of Menkaure, along with their associated pyramid complexes and the Great Sphinx. All were built during the Fourth Dynasty of the Old Kingdom of ancient Egypt, between c. 2600 – c. 2500 BC. The site also includes several temples, cemeteries, and the remains of a workers' village.

The site is at the edge of the Western Desert, approximately 9 km (5.6 mi) west of the Nile River in the city of Giza, and about 13 km (8.1 mi) southwest of the city centre of Cairo. It forms the northernmost part of the 16,000 ha (160 km; 62 sq mi) Pyramid Fields of the Memphis and its Necropolis UNESCO World Heritage Site, inscribed in 1979. The pyramid fields include the Abusir, Saqqara, and Dahshur pyramid complexes, which were all built in the vicinity of Egypt's ancient capital of Memphis. Further Old Kingdom pyramid fields were located at the sites Abu Rawash, Zawyet El Aryan, and Meidum. Most of the limestone used to build the pyramids originates from the underlying Mokattam Formation.

A sarcophagus (pl.: sarcophagi or sarcophaguses) is a coffin, most commonly carved in stone, and usually displayed above ground, though it may also be buried. The word sarcophagus comes from the Greek σάρξ sarx meaning "flesh", and φαγεῖν phagein meaning "to eat"; hence sarcophagus means "flesh-eating", from the phrase lithos sarkophagos (λίθος σαρκοφάγος), "flesh-eating stone". The word also came to refer to a particular kind of limestone that was thought to rapidly facilitate the decomposition of the flesh of corpses contained within it due to the chemical properties of the limestone itself.

Mining is the extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains a valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation or restoration of the land after the mine is closed. Mining materials are often obtained from ore bodies, lodes, veins, seams, reefs, or placer deposits. The exploitation of these deposits for raw materials is dependent on investment, labor, energy, refining, and transportation cost.

The Great Pyramid of Giza is the largest Egyptian pyramid. It served as the tomb of pharaoh Khufu ("Cheops"), who ruled during the Fourth Dynasty of the Old Kingdom. Built c. 2600 BC over a period of about 26 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northeastern end of the line of the three main pyramids at Giza.

Initially standing at 146.6 metres (481 feet), the Great Pyramid was the world's tallest human-made structure for more than 3,800 years. Over time, most of the smooth white limestone casing was removed, which lowered the pyramid's height to the current 138.5 metres (454.4 ft); what is seen today is the underlying core structure. The base was measured to be about 230.3 metres (755.6 ft) square, giving a volume of roughly 2.6 million cubic metres (92 million cubic feet), which includes an internal hillock. The dimensions of the pyramid were 280 royal cubits (146.7 m; 481.4 ft) high, a base length of 440 cubits (230.6 m; 756.4 ft), with a seked of ⁠5+1/2⁠ palms (a slope of 51°50'40").

The Great Sphinx of Giza is a limestone statue of a reclining sphinx, a mythical creature with the head of a human and the body of a lion.

The monument was sculpted from the limestone bedrock of the Eocene-aged Mokattam Formation and faces east on the Giza Plateau, on the west bank of the Nile in Giza, Egypt. The oldest known monumental sculpture in Egypt, the Sphinx is part of the Memphite Necropolis and is a UNESCO World Heritage Site.

The Mokattam Formation is a Middle Eocene-aged geological formation in northern Egypt. Consisting of nummulitic marine limestone outcropping across the Mokattam Hills, it has been extensively quarried from Ancient Egypt to the present day, and represents the source material for most of the famous archeological sites of Greater Cairo, most notably the Giza pyramid complex, the Great Sphinx, and much of Historic Cairo.

The age of the formation is thought to span from the late Lutetian to the Bartonian, depending on the member (Building Stone or Giushi). However, some authors treat the Giushi Member as its own geologic formation, which would restrict the Mokattam to just the Lutetian.

Lithography (from Ancient Greek λίθος (líthos) 'stone' and γράφω (gráphō) 'to write') is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps. Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography.

Traditionally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plate. The stone was then treated with a mixture of weak acid and gum arabic ("etch") that made the parts of the stone's surface that were not protected by the grease more hydrophilic (water attracting). For printing, the stone was first moistened. The water adhered only to the etched, hydrophilic areas, making them even more oil-repellant. An oil-based ink was then applied, and would stick only to the original drawing. The ink would finally be transferred to a blank sheet of paper, producing a printed page. This traditional technique is still used for fine art printmaking.

The Everglades is a natural region of flooded grasslands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin within the Neotropical realm. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. Water leaving the lake in the wet season forms a slow-moving river 60 miles (97 km) wide and over 100 miles (160 km) long, flowing southward across a limestone shelf to Florida Bay at the southern end of the state. The Everglades experiences a wide range of weather patterns, from frequent flooding in the wet season to drought in the dry season. Throughout the 20th century, the Everglades suffered significant loss of habitat and environmental degradation.

Human habitation in the southern portion of the Florida peninsula dates to 15,000 years ago. Before European colonization, the region was dominated by the native Calusa and Tequesta tribes. With Spanish colonization, both tribes declined gradually during the following two centuries. The Seminole, formed from mostly Creek people who had been warring to the North, assimilated other peoples and created a new culture after being forced from northern Florida into the Everglades during the Seminole Wars of the early 19th century. After adapting to the region, they were able to resist removal by the United States Army.

The Kish tablet is a limestone tablet found at the site of the ancient Sumerian city of Kish in modern Tell al-Uhaymir, Babylon Governorate, Iraq. A plaster cast of the tablet is in the collection of the Ashmolean Museum, while the original is housed at the Iraq Museum in Baghdad. It should not be confused with the Scheil dynastic tablet, which contains part of the Sumerian King List and is also sometimes called the Kish tablet.

The signs on the Kish tablet, possibly related to proto-cuneiform, are purely pictographic, and have not been deciphered or demonstrated to correspond to any currently known human language. It has been dated to the Late Uruk period (c. 3200–3000 BC).
