Mineral springs

Carbon dioxide, CO. Carbon dioxide is present in air and escapes from fissures in the earth in volcanic regions and where mineral springs occur. It may be prepared by ... 

It does not occur free in nature combined it is found in small units in nearly all igneous rocks and in the waters of many mineral springs. Lepidolite, spodumeme, petalite, and amblygonite are the more important minerals containing it. 

Gr. xenon, stranger) Discovered by Ramsay and Travers in 1898 in the residue left after evaporating liquid air components. Xenon is a member of the so-called noble or "inert" gases. It is present in the atmosphere to the extent of about one part in twenty million. Xenon is present in the Martian atmosphere to the extent of 0.08 ppm. the element is found in the gases evolved from certain mineral springs, and is commercially obtained by extraction from liquid air. 

Travertine is a calcium carbonate formed by chemical precipitation from natural hot-water mineral springs. In appearance and use it is closely akin to... 

Occurrence. Magnesium bromide [7789-48-2] MgBr2, is found in seawater, some mineral springs, natural brines, inland seas and lakes such as the Dead Sea and the Great Salt Lake, and salt deposits such as the Stassfurt deposits. In seawater, it is the primary source of bromine (qv). By the action of chlorine gas upon seawater or seawater bitterns, bromine is formed (see Chemicals frombrine). 

Carbon dioxide is present in air and is a eonstituent of natural gas eseaping from mineral springs and fissures in the earth s surfaee. It is also the ultimate produet of eombustion of earbon and its eompounds. Laboratory seale preparation usually entails reaetion between dilute hydroehlorie aeid and marble (ealeium earbonate) ...

Xenon occurs in the atmosphere at trace concentrations. It also occurs in gases from certain mineral springs. Xenon also is a fission product of uranium, plutonium, and thorium isotopes induced by neutron bombardment. The radioactive fission product, xenon-135, has a very high thermal neutron cross-section. The element has been detected in Mars atmosphere. 

In 1838 Klaus, with his student assistant Kabalerov, made an analysis of the water from the Sergievsky Mineral Springs, which provided the data for his dissertation for the doctorate in pharmacy. Immediately after receiving this degree, he was made extraordinary professor at the University, and six years later he was promoted to the position of ordinary professor. 

A few papers in the Memoires of the Paris Academy and quite a few in the Philosophical Transactions of the Royal Society took careful notice of the air to be found in many mineral spring waters. In addition to these, there were a couple of papers on the cause of the asphyxiation of small...

Hydrogen sulphide is present in many mineral springs, and even free sulphur is occasionally found therein.2 Many metallic sulphides, for example, iron pyrites, galena, zinc blende, stibnitc and cinnabar, occur abundantly. Sulphur dioxide, sulphites, sulphuric acid and sulphates are also found in nature, more especially in waters springing from volcanic earth, whilst the sulphates of certain metals such as calcium, barium and magnesium exist in large deposits. 

Carbon dioxide issues in abundance from the earth, it occurs in mineral springs, it is formed during respiration of mammals and passes into the atmosphere, and is evolved in the fermentation process in the decay of org matter. It is produced commercially from the decompn of carbonates, by the combustion of carbonaceous materials such as coke, coal, oil natural gas... 

Fig. 6.24 Fingerprint diagrams of data obtained in a study of mineral springs in Switzerland (Vuatax, 1982). Three compositional groups emerged Na-S04, Ca(Na)-HC03, and Ca-S04. In this case lithology was identified as the major control.

Fig. 9.2 Stable hydrogen and oxygen isotopic composition of the Hamei Zohar and Hamei Yesha mineral springs, Dead Sea shores. The linear correlation indicates that the springs water is formed by intermixing of Dead Sea brine with local fresh water. (From Gat et al., 1969.)...

Fig. 9.27 Isotopic composition and chlorinity of warm springs at the Bay of Maliakos (see Fig. 9.24). Values lie on a mixing line with seawater, proving that the last one is intermixing in the mineral springs. (From Stahl et al., 1974.)...

Exercise 9.1 From the information included in Fig. 9.2, calculate the percentage of Dead Sea brine intermixed in the Hamei Yesha mineral spring. Do the calculation using the redundant information available, that is, use the <5D and the <5180 values. 

The corresponding <5D values are - 30%o for the fresh water, 0%o for the Dead Sea, — 13%o for Hamei Yesha, and the calculated contribution of Dead Sea brine to the mineral spring is 55%. The values of 57% and 55% are very close, considering the analytical errors and the inaccuracy of reading the data from a graph.
