Helcionopsis radiatum is an extinct species of paleozoic monoplacophoran in the family Tryblidiidae. This species was first named as Tryblidium radiatum and described from Silurian in crystalline limestone of Wialmsudd near Fårösund in Sweden by Gustaf Lindström in 1884. Lindsröm found only one specimen.

Trondra is made up of steeply inclined dalradian rocks; mainly quartz and mica rich schists but with some crystalline limestone in the north which provide fertile soils around Cauldhame and Cutts. The hills are covered in grass and heather, with trees being few and far between, much like the rest of the Shetland Islands.

To the north of Sawel is County Londonderry, and to the south, County Tyrone. The summit is high and is composed of crystalline limestone. Around the peak, there is "montane heathland", with plant life including heather, bilberries and cowberries, although this is being damaged by hillwalking and grazing. Sawel is the source of the River Faughan, a long tributary of the River Foyle.

The rock formations are marine sediments, remnants of the prehistoric Tethys Sea, which used to cover the area running roughly east–west, halfway across the present Dead Sea. Along the Zarqa, crystalline limestone alternating with shale was found. The next layer is a 20-30 meter high layer of gypsum, argillaceous marly lime, shales and iron-rich stone and sandstone. This layer is rich in fossils.

Fine mosaic floors are a notable feature of the villa. The tesserae included blue and crystalline limestone, green volcanic stones, brown sandstone, and red-brick cuttings, encircled with a red, white, blue and brown border. A record from 1907 described the relics as Samian ware pieces; bronze coins of Maximinus Thrax, Victorinus, and Constantius Chlorus; as well as roofing materials. The site was again excavated between 1938 and 1948.

The Licking Creek Limestone of the Helderberg Group was first introduced by F. M. Swartz in 1938, and was described more fully in 1939.Swartz, F.M., 1939, The Keyser limestone and Helderberg group, IN Willard, Bradford, Swartz, F.M., and Cleaves, A.B., The Devonian of Pennsylvania: Pennsylvania Geological Survey General Geology Report, 4th series, no. 19-G, p. 29-91. The unit consists of layers and nodules of black chert interbedded with light-gray crystalline limestone.

These bluffs and buttes are remnants of a higher gravel plain. On the ridge between the forks of the Mary River, there are two low, rocky buttes, which, on account of the general low relief of the region, stand out as landmarks. These buttes are composed of white crystalline limestone, whose bedding is obscured by jointing and cleavage. Except for these buttes, the bed rock, as indicated by fragments found on the surface, consists of calcareous mica schists.

Andradite is a calcium-iron garnet, Ca3Fe2(SiO4)3, is of variable composition and may be red, yellow, brown, green or black. The recognized varieties are topazolite (yellow or green), demantoid (green) and melanite (black). Andradite is found both in deep-seated igneous rocks like syenite as well as serpentines, schists, and crystalline limestone. Demantoid has been called the "emerald of the Urals" from its occurrence there, and is one of the most prized of garnet varieties.

Paleozoic allochthon formations are found in the lower rock units in the northeast margin of the Dinarides. These rocks are found in isolated areas in the northwest, central, eastern and southeastern Bosnia and are made up of metapsammite, metapelite and smaller amounts of volcanic and carbonate rock. The Southeastern Paleozoic Zone comprises phyllite, schistose metasandstone and crystalline limestone, overlain by slate and more phyllite. Permian rocks are mainly red beds with slate, metasandstone, limestones, gypsum, anhydrite and conglomerates.

The scapolite limestones and contact metamorphic rocks. As silicates rich in calcium, it is to be expected that these minerals will be found where impure limestones have been crystallized by contact with an igneous magma. Even marialite (the variety richest in soda) occurs in this association, being principally obtained in small crystals lining cavities in ejected blocks of crystalline limestone at Vesuvius and the craters of the Eifel in Germany. Scapolite and wernerite are far more common at the contacts of limestone with intrusive masses.

A round piece of white crystalline limestone, found at the back of the altar, may have served as the base for a statue of a deity. Stone benches stood along both long walls, while along the short walls the excavators found groups of small pits sunk into the floors. These were found to contain the remains of burnt bones, horns, pottery, and a great quantity of ash. A piece of painted plaster indicates the walls were perhaps even painted and decorated, like those from the Ghassulian type site at Teleilat al- Ghassul.

The type locality is Coal Mine No. 44, Kopeisk, Chelyabinsk coal basin, Chelyabinsk Oblast, Southern Urals, Russia, and type material is held at the Fersman Mineralogical Museum, Academy of Sciences, Moscow, Russia. Ellestadite is a skarn mineral. It occurs associated with diopside, wollastonite, idocrase, monticellite, okenite, vesuvianite, calcite and others at Crestmore, Riverside County, California, US. At Crestmore a contact zone exists between crystalline limestone and granodiorite. The area was quarried for limestone in the early 1900s, revealing varied associations of metamorphic minerals, including ellestadite (named as wilkeite) with garnet, vesuvianite and diopside, in blue calcite.

Remains of the city walls, with traces of one gate and several towers, of a total length of over three miles, still exist, and belong to three different periods, in all of which the crystalline limestone of the locality is used. Bricks were also employed in later times; their form is peculiar to this place, each having two rectangular channels on one side, and being about 1.5 inches square, with a thickness of nearly 4 inches They all bear Greek brick-stamps. There are some remains of cisterns on the site, and, various other traces of buildings.

The strata of all walks of life are developed from the old to the new for the Early Paleozoic strata, the Paleozoic strata, the Mesozoic strata, and the Neogene stratigraphic strata. In the early Paleozoic, the horizon was in a state of slow decline, with large-scale transgression, and the deposition of thick shallow sand shale and carbonate rock formations. The Ordovician rocks in the Paleozoic are mainly light gray and gray thick layered limestone, crystalline limestone and leopard skin limestone; the Carboniferous rocks are mainly gray-white siltstone, clay rock, shale and thin layer limestone. Several layers of coal; the two rocks are mainly grayish white, dark gray sandstone and variegated mudstone and brown shale, rich in plant fossils.

Viaduct support of mineral water supply for the bottling plant Mineral water springs are numerous, with a close and stable chemical composition over time, with variable but sufficient flows to be economically used and are currently the main economic engine of the resort. The mineralization characters fall into the group of bicarbonate, calcium, magnesium, carbonate and hypotonic mixed mineral waters. The springs of the Borsec Depression occur in two groups - the northern one of greater importance - the springs line having originating from dolomitic crystalline limestone, sources characterized by the accumulation of water in the cracks and the karstic voids (springs 1, 2, 3, 5, 6); and the southern group - the line of springs cantonated in calcareous tuff with a restricted circulation of water through cracks and areas of alteration (springs 10, 11, 15). The most important springs qualitative and as flow of the resort are the springs 1 and 2.
