Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds
Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

About Perspectives of Studying the Kimberlite Indicator Minerals
Вестник Пермского университета. ГеологияAnalysis of the results of carried out investigations of mantle modules in kimberlite diatremes of main diamondiferous regions of the Siberian platform was made. Morphology and chemistry of garnets, chrome-diopsides, clinopyroxenes, picroilmenites, chromites and chrome-spinellids were investigated.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract The voluminous active volcanoes of the Revillagigedo Islands of Socorro and San Benedicto in the east Pacific Ocean exhibit hotspot geochemistry. However, the presence of a deep mantle plume has not been seismologically confirmed. Instead, a fossil subducted slab is identified in the lower mantle underneath the volcanoes. Moreover, the islands

Petrography and mineral chemistry of Northeast Africa 053—A remnant of Martian crystal mush
Meteoritics &Planetary Science, Volume 61, Issue 4, Page 621-643, April 2026.Abstract In Earth's igneous systems, crystal mushes, crystal‐rich frameworks permeated by silicate melt, represent a common and fundamental stage in the evolution of magma bodies. However, whether crystal mushes occur within Martian igneous systems and play a comparable role is unknown. Here, we present a comprehensive petrography and mineral chemistry
