A New Approach to Characterizing Deposit Type Using Mineral Inclusion Assemblages in Gold Particles
Economic Geology, 2021 Mineral inclusions within native gold are features of lode gold occurrences that are preserved in detrital particles. Inclusion assemblages in populations of gold particles in placers from specific localities are revealed through inspection of polished

Discovery of davemaoite, CaSiO3-perovskite, as a mineral from the lower mantle
Science, 2021 Description Lower mantle “garbage can” Calcium silicate perovskite has finally been identified in a natural sample and now has the mineral name davemaoite. Tschauner et al. discovered the type mineral trapped at high pressure and temperature as a diamond

Trace Mineral Nutrition of Grazing Beef Cattle
Animals, 2021 Simple Summary The trace mineral nutrition of grazing beef cattle is an essential, but often complicated component of the management program. Throughout the annual cycle, forage is the primary source of trace mineral supply to grazing cattle, but ...

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.

Aquamarine from Massangana batholith, Rondônia State: mineral chemistry and fluid inclusion data
REM: International Engineering Journal, 2020 Beryl is usually found in granite-pegmatite systems. The addition of chromophore elements (V, Cr, Mn, Fe) into the crystalline structure favors color changes in beryl and thus generates some of the world’s expensive gems such as emerald, morganite ...

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 ...
