Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone. Limestone has long fascinated earth scientists because of its rich fossil ...

We applied these to experiments in Bedford limestone in which spherical/cylindrical explosives (0.2 to 1.9 g) were centrally placed in 1.2- to 3-cm diameter cavities.

Enigmatic structures in the shape of inverted rounded cones are very common in a discrete horizon of the upper Stoner Limestone Member (Stanton Limestone Formation, Lansing Group, Upper Pennsylvanian) in southeastern Nebraska. These structures are 100–300 mm in diameter, but rare, very large examples attain 1300 mm in diameter. On bedding planes, individual structures are conspicuously ...

Soft-sediment deformation structures that have been attributed to these triggers are considered below. 2.4. Liquefaction in experiments. Following exploratory experiments that induced liquefaction by striking a bench supporting a tank of sediment and water (Anketell et al., 1970, Kuenen, 1958, Selley, 1969, Selley and Shearman, 1962), controlled and repeatable experiments on the effects of ...

Limestone aggregate is commonly selected for this purpose. Flux Stone – When crushed, lime can be used for smelting and other metal refining processes. The heat of smelting causes the aggregate to combine with impurities and may be removed from the process as a slag.

The second lithofacies occurs in marly limestone and marls, white to light brown in colour, with a variable bed thickness from 2 to 50 cm, frequently with very thin, mm-scale lamination. The third lithofacies shows conglomerate layers that are visible in various intervals of the stratigraphic sections ( Fig. 3 ) and have a thickness from 5 to ...

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
