Mineral inclusions in Brazilian diamonds
Physics and Chemistry of the Earth, 1975Abstract Minerals included in diamonds from several localities in Brazil have been examined. The minerals observed are olivine, enstatite, chrome-pyrope and pyrope-almandine. These minerals have similar compositions to those previously reported for inclusions from other worldwide localities. In addition rutile, ilmenite, zircon, quartz and pyrrhotite

Fluid inclusions are minute samples of fluids trapped in mineral cavities, which are generally smaller than 100 µm in diameter. Fluid inclusions in the mm-range are rather rare. The fluids were trapped during the growth or recrystallisation of the host mineral at a certain event in the geological history of the host rock.

Inclusion shape, mineral texture and liberation
International Journal of Mineral Processing, 1989Abstract The effect of an ore's texture on liberation was explored using simplified texture models composed by a continuous phase and an inclusional phase with different geometric aspects of the inclusions. Unexpectedly, a parameter called the “textural rank” was developed that may be useful for a quantitative characterization of the rock's textures.

Elements of Eoarchean life trapped in mineral inclusions
Nature, 2017Metasedimentary rocks from Isua, West Greenland (over 3,700 million years old) contain 13C-depleted carbonaceous compounds, with isotopic ratios that are compatible with a biogenic origin. Metamorphic garnet crystals in these rocks contain trails of carbonaceous inclusions that are contiguous with carbon-rich sedimentary beds in the host rock, where ...

Fluid inclusions in fluorite mineralizations of northwestern Sicily, Italy
Chemical Geology, 1987Abstract Several fluorite ± barite mineralizations, mainly controlled by post-Pliocene disjunctive faults, occur in silicified and altered Mesozoic limestones in the area of Termini Imerese (NW Sicily). In this study, we examined fluid inclusions in fluorite from the localities of Rocca Grande and Poggio Balate.

P–V–T relationships and mineral equilibria in inclusions in minerals
Earth and Planetary Science Letters, 2006Abstract When a mineral is included in another, the pressure on the two is the same. As pressure and temperature then change, the pressure on the inclusion is likely to become increasingly different to the pressure on its host as a consequence of the two minerals having different equations of state (i.e.

Endogenous Mineralization, Inclusions, and Deposition Disorders
2008The entities discussed in this chapter are diverse. Many come under the heading of metabolic diseases, which may be congenital or acquired. Others have, or act through, an immunologic basis. A few have a single identifiable cause. Some represent a common tissue response to multiple identified causes, while others appear to have no known causes.
