This requires study of molecules with high resolutions looking at bonding scenario how heavy isotopes are bonded to each other - leading to knowledge of stability of molecule depending on its isotopic structure.
Oxygen has three stable isotopes 16 O, 17 O and 18 O and Carbon has two 13 C, 12 C. A 12 C 16 O 2 molecule composed only with most abundant isotopes of constituent elements is called a ' monoisotopic ' species.
When only one atom is replaced with heavy isotope of any constituent element ie, 13 C 16 O 2 , it is called a 'singly-substituted' species.
Likewise, when two atoms are simultaneously replaced with heavier isotopes eg. The 'clumped' species 13 C 16 O 18 O for CO 2 is a doubly substituted CO 2 molecule.
Isotopically substituted molecules have higher mass. As a consequence, molecular vibration reduces and the molecule develops a lower zero point energy see Kinetic isotope effect.
The abundances of certain bonds in certain molecules are sensitive to temperature at which it formed e. This information has been exploited to form the foundation of clumped isotope geochemistry.
Clumped isotope thermometers have been established for carbonate minerals like dolomite ,   calcite ,  siderite  etc and non-carbonate compounds like methane  and oxygen.
Clumped isotopic analysis is usually done by gas source mass spectrometry where the CO 2 liberated from magnesite by phosphoric acid digestion is fed into the isotope ratio mass spectrometer.
In such scenario, one needs to ensure that liberation of CO 2 from magnesite is complete. Due to digestion at this high temperature, some of the 13 C- 18 O bonds in the liberated CO 2 are broken leading to reduction in abundance of 'clumped' CO 2 during phosphoric acid digestion of carbonates.
To account for this additional analytical artifact , a correction called the 'acid fractionation correction' is added to the magnesite clumped isotope value obtained at temperature of digestion.
Since the CO 2 gas is liberated from carbonate mineral during acid digestion, leaving one O behind- a fractionation occurs, and the isotopic composition of the analyzed CO 2 gas needs to be corrected for this.
Different researchers have also used other fractionation factors like dolomite fractionation factor. While measuring samples of unknown composition, it is required to measure some standard materials see Reference materials for stable isotope analysis.
With internal standards and reference materials, analytical session is routinely monitored. Standard materials are majorly calcite and marble.
To convert clumped isotope data into temperature, a calibration curve is required which expresses the functional form of temperature dependence of clumped isotope composition.
No mineral specific calibration exists for magnesite. Based on some experimental data  where mineral precipitation temperature and clumped isotope derived temperature doesn't match, a need of mineral specific calibration emerges.
Using clumped isotope derived temperature, C and O isotopic composition of the parental fluid can be calculated using known magnesite-fluid isotope fractionation factors, since fractionation is temperature dependent.
Reported magnesite-fluid O and C isotope fractionation factors in literature are not in agreement with each other. In low temperature, thus, hydrous Mg-carbonates hydromagnesite , nesquehonite etc.
It is possible to convert these phases into magnesite by changing temperature by mineral dissolution-precipitation or dehydration.
While so happens, an isotope effect associated can control the isotopic composition of precipitated magnesite. Disequilibrium processes like degassing, rapid CO 2 uptake etc.
They variably enrich or deplete the system in heavy isotopes of C and O. Since clumped isotope abundance depends on abundance of isotopes of C and O, they are also modified.
Another very prominent effect here is that of pH of precipitating fluid. Crystalline and cryptocrystalline magnesites have very different mineral structures.
While crystalline magnesite has a well developed crystal structure, the cryptocrystalline magnesite is amorphous- mostly aggregate of fine grains.
Since clumped isotopic composition depends on specific bonding, difference in crystal structure is very likely to affect the way clumped isotopic signatures are recorded in these different structures.
Magnesite can be formed via talc carbonate metasomatism of peridotite and other ultramafic rocks. Magnesite is formed via carbonation of olivine in the presence of water and carbon dioxide at elevated temperatures and high pressures typical of the greenschist facies.
Magnesite can also be formed via the carbonation of magnesium serpentine lizardite via the following reaction :. However, when performing this reaction in the laboratory, the trihydrated form of magnesium carbonate nesquehonite will form at room temperature.
The fundamental difficulty to nucleate anhydrous magnesium carbonate remains when using this non-aqueous solution.
Not cation dehydration, but rather the spatial configuration of carbonate anions creates the barrier in the low-temperature nucleation of magnesite.
Magnesite has been found in modern sediments, caves and soils. Magnesite was detected in meteorite ALH and on planet Mars itself.
Magnesite was identified on Mars using infra-red spectroscopy from satellite orbit. Low-temperature formation has been suggested for the magnesite from the Mars-derived ALH meteorite.
In October RHI AG merged with Magnesita, a Brazilian competitor, and then abandoned its listing on the Vienna Stock Exchange and instead secured a listing on the London Stock Exchange as RHI Magnesita.
The company produces roughly 3 million tons of refractory products each year at 35 main production and 10 main raw material sites around the world.
