Application of fluid inclusions in mineral exploration
Journal of Geochemical Exploration, 1991Abstract Fluid inclusions provide information on the genesis of mineral deposits and can be used in mineral exploration. A hidden orebody at the Sangdong tungsten ore deposit was found by fluid inclusion study. Maximum homogenization temperature values obtained from quartz in skarn at Sangdong delineated the main channel of ore fluid, as well as ...

Inclusions in diamond and the mineral chemistry of the upper mantle
Physics and Chemistry of the Earth, 1979Abstract During the last decade significant progress regarding our understanding of the mineralogy and geochemistry of the earth's upper mantle has been achieved through studies of the ultramafic and eclogitic xenoliths in kimberlite, and of mineral inclusions in diamond.

Inclusion of tobacco exposure as a predictive factor for decreased bone mineral content.
Nicotine & Tobacco Research, 2004Tobacco exposure has been implicated as a risk factor for decreased bone density, which might result in osteoporosis. Cotinine, a metabolite of nicotine, is commonly used as a marker for tobacco exposure (active or passive).

Synthesis of diamonds with mineral, fluid and melt inclusions
Lithos, 2016Abstract Experiments on the synthesis of inclusions-bearing diamond were performed in the SiO 2 –((Mg,Ca)CO 3 –(Fe,Ni)S system at 6.3 GPa and 1650–1750 °C, using a multi-anvil high pressure apparatus of the “split-sphere” type. Diamond synthesis was realized in the “sandwich-type” experiments, where the carbonate–oxide mixture acted as a source of ...

Shocked quartz and other mineral inclusions in Australasian microtektites
Geology, 2010We report the occurrence of microscopic inclusions of shocked quartz plus a Zr phase and trace of Fe oxide crystallites in Australasian microtektites recovered from deep-sea sediment cores within 2000 km of Indochina. The shocked quartz and the Zr phase are interpreted as relicts of the target rock. Furthermore, the internal homogeneity of Australasian

Approximately 1,330 fluid inclusions were studied in samples of ore and gangue minerals from both massive ore and late-stage vugs from a series of Appalachian deposits and five active mines in the East Tennessee zinc districts. Most primary inclusions in

Assessment of the Distribution of Mineral Inclusions and Coal Crushing
Coke and Chemistry, 2019When coal is crushed, it fractures along the bedding planes and also along the boundaries with mineral inclusions. In the latter case, the mineral inclusions are released and separated from the coal. The release of the mineral inclusions may be precisely measured, but special instruments are required and these methods are of little utility.

A STUDY OF THE COMPOSITION OF MINERAL “CAPTIVES” IN POLYPHASE INCLUSIONS
International Geology Review, 1962Topaz from pegmatites of the Volyniya commonly contain polyphase inclusions, within which 8 or more mineral “captives” (crystalloids) are found, which result from supersaturated solution in vacuoles. By opening inclusions with the aid of a microdrill or breaking the topaz along the cleavage the author determined the crystallo-optical constants and some

A study on gas inclusions in minerals. Analysis of the gases from micro-inclusions in allanite
Geochimica et Cosmochimica Acta, 1973Abstract In order to determine the chemical composition of the gases from micro-inclusions in allanite a comparative study, using the methods of heating to decrepitation and grinding in vacuum was undertaken. The dependence of gas composition on the grain size was studied, too.

The decrepitation method applied to minerals with fluid inclusions
Economic Geology, 1948A simple technique is presented and its theory discussed whereby minerals with fluid inclusions are heated until the fluid escapes. The escape (decrepitation) is recorded by its audible rather than its visible effects. Several examples are described to illustrate various applications.
