Mineral inclusion assemblage and detrital zircon provenance

open access: yesChemical Geology, 2018
Abstract Mineral inclusions are common in magmatic zircon and a potentially rich source of petrologic information. Controls on the relative proportions of inclusion phases, specifically early-crystallizing minerals such as apatite and late-crystallizing phases such as quartz, K-feldspar, and muscovite, have not been systematically studied.

Mineral Inclusions in Lithospheric Diamonds

open access: yesReviews in Mineralogy and Geochemistry, 2022
Initially, it may seem extremely daunting to be sitting in front of several thousand carats of small diamonds, knowing that the likelihood of finding a diamond with a meaningful inclusion is about 1% of that parcel.

Inclusion shape, mineral texture and liberation

International Journal of Mineral Processing, 1989
Abstract 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.

Origin, properties, and structure of breyite: The second most abundant mineral inclusion in super-deep diamonds

American Mineralogist, 2020
Earth’s lower mantle most likely mainly consists of ferropericlase, bridgmanite, and a CaSiO3- phase in the perovskite structure. If separately trapped in diamonds, these phases can be transported to Earth’s surface without reacting with the surrounding ...
