Latomia = Latin for Quarry
Law (of the stone) = the growth pattern of a stone, detected through direction of its veins.
Ledger = stone slab laid flat over a grave.
Leshan Buddha = the Leshan Buddha, near Leshan in Sichuan province, is the largest stone-carved Buddha in the world. Construction began during the Tang Dynasty in 713, and was completed in 803. It is 71 metres (or 233 feet) tall.
Lime mortar = Lime mortar is not the same as cement and is one of the oldest known types of mortar, dating back to 4th BC, used in Ancient Rome and Greece.
An example of a lime mortar mixture:
Recipe as used in St Magnus, Kirkwall, Orkney =
1 part red quarry dust +1part blue-grey quart dust+1part sand+1part lime
Limestone is a sedimentary rock composed largely of the mineral calcite which is calcium carbonate. Like most other sedimentary rocks, lime stones are composed of grains; which are either skeletal fragments of marine organisms or other small grains (sometimes referred to as ooids, peloids, intraclasts, or extraclasts). Some lime stones, particularly those that form in caves or travertine, do not consist of grains at all and are formed completely by the reconsolidation of calcite or aragonite bearing liquid. Limestone is the determining element in karst landscapes. Most cave systems are through limestone bedrock.
Limestone is essential for the creation of cement and mortar. It can be pulverized to use as a soil conditioner, or crushed for various aggregate uses, such as for the solid base for roads.
Limestone is used in glass making, added to paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler it is an ingredient in toothpaste, added to bread and cereals as a source of calcium, ground up and given to poultry as a supplement to strengthen egg shells.
Limestone can be dissolved in purified water to reintroduce essential nutrients and also to increase its alkalinity and prevent pipe corrosion.
Geological formations of limestone are perhaps the best petroleum reservoirs. It is used to suppress methane explosions in coal mines.
Lintel = A stone across the top of two uprights like those on the sarsen circle and the trilithons at Stonehenge
Lithic = adjective for stone
Lithoid = of the nature or structure of stone.
Lithopedion, -ium = a dead extra-uterine foetus, impregnated with calcareous matter meaning essentially that it has turned to stone. A lithopedion (Greek:litho = stone; pedion = child), or stone baby, is a rare phenomenon which occurs most commonly when a fetus that dies during an abdominal pregnancy and is too large to be reabsorbed by the body. It calcifies on the outside, shielding the mother's body from the dead tissue of the baby and preventing infection. Lithopedia may occur from 14 weeks gestation to full term. It is not unusual for a stone baby to remain undiagnosed for decades, and it is often not until a patient is examined for other conditions or a proper examination is conducted that includes an X-ray, that a stone baby is found. The oldest reported case is that of a 94 year old woman whose lithopedion had been present for more than 60 years.
The condition was first described in a treatise by the physician Albucasis in the 10th century AD, but fewer than 300 cases have been noted in 400 years of medical literature. The earliest lithopedion is one found in an archaeological excavation, dated to 1100 BC.
Lithosphere = the solid outer portion of the Earth consisting of the crust and upper mantle, a lithosphere approximately 100 km (62 miles) thick. [From litho- (stone) + -sphere.]
Live stone = a term applied to a stone without a controlling grain or crystal structure. It can be sawn or squared up in any direction.
Lodestone = magnetite ( an oxide of iron) possessing magnetic polarity; something that strongly attracts. . "Lode" comes from the Old English "l?d," which means "way, journey, course."
Loess = softest stone is an Aeolian sediment formed by the accumulation of wind-blown silt and lesser and variable amounts of sand and clay that are loosely cemented by calcium carbonate. It is usually homogeneous and highly porous and is traversed by vertical capillaries that encourage the sediment to fracture and form vertical bluffs.
The word loess, with connotations of origin by wind-deposited accumulation, is of German origin and means "loose." It was first applied to Rhine River valley loess about 1821.
Logan stone = a poised heavy stone rocking at a touch.
