Mineral inclusions in diamonds may be synchronous but not syngenetic [PDF]
Nature Communications, 2017 AbstractIt is widely assumed that mineral inclusions and their host diamonds are ‘syngenetic’ in origin, which means that they formed simultaneously and from the same chemical processes. Mineral inclusions that, instead, were formed earlier with respect to diamonds are termed protogenetic. However, minerals can have the same age as the diamonds in that

Raman Elastic Geobarometry For Anisotropic Mineral Inclusions [PDF]
American Mineralogist, 2018 Elastic geobarometry for host-inclusion systems can provide new constraints to assess the pressure and temperature conditions attained during metamorphism. Current experimental approaches and theory are developed only for crystals immersed in a hydrostatic stress field, whereas inclusions experience deviatoric stress.

How large are departures from lithostatic pressure? Constraints from host-inclusion elasticity [PDF]
, 2015 Minerals trapped as inclusions within other host minerals will develop non-lithostatic pressures during both prograde and retrograde metamorphism because of the differences between the thermo-elastic properties of the host and inclusion phases.

Micro-crystalline inclusions analysis by PIXE and RBS [PDF]
, 2008 A characteristic feature of the nuclear microprobe using a 3 MeV proton beam is the long range of particles (around 70 \mu m in light matrices). The PIXE method, with EDS analysis and using the multilayer approach for treating the X-ray spectrum allows ...

Dawsonite as a daughter mineral in hydrothermal fluid inclusions [PDF]
Contributions to Mineralogy and Petrology, 1971 Traces of dawsonite (NaAlCO3(OH)2) are extremely common as a daughter product in fluid inclusions in gold-quartz veins and altered wallrock of the Oriental mine, Alleghany district, California. A very similar daughter salt occurs in hydrothermal inclusions in quartz from 19 other mining localities of worldwide distribution.

Petrogenesis of mineral micro-inclusions in an uncommon carbonado
European Journal of Mineralogy, 2011 A unique Brazilian sample of a carbonado, displaying unusually large amount of diamond clasts merged within a fine-grained diamond matrix, has been studied by Secondary Ion Mass Spectrometry (SIMS), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) on Focused Ion Beam (FIB)-extracted foils. We found for the first time in the
