Eventually, it becomes unstable as a consequence of internal heating [in the region above the core-mantle boundary], and the resulting diapirs become the source plumes of oceanic island basalts (OIB) and hot spot volcanism.” This interpretation has been widely accepted since then and has gained...
2012). Black lines show the calculated S content of silicate melt at sulfide saturation according to the model of O’Neill and Mavrogenes (2002) settingaFeS equal to 0.5 and 0.6, as indicated. Yellow circles are measurements of olivine

Only last year, for example, researchers from Bath University used neutron techniques to map structural changes within oxide glasses and liquids - research that could provide a new tool to investigate the environmental conditions that melt the Earth's interior and produce volcanism at the surface. W...
The unit consists of ignimbritic unwelded deposits of rhyolitic/rhyo-dacitic pyroclasts deposited during the Burdigalian phase of the explosive volcanism in northern Sardinia. The presence of fossils (including a clearly Mesozoic ammonite) was very useful in establishing the origin of the initial ...
Petrography Based on petrographic characteristics, Fuerteventura carbonatites are grouped into two main types: (i) calcio–carbonatites (the most dominant type) and (ii) silico–carbonatites, when the amount of silicate phases reach up to 50% of the rock volume. Fuerteventura carbonatites are medium...
