Post-aragonite phase of CaCO3, experimentally known to be stable above 40 GPa [S. Ono, T. Kikegawa, Y. Ohishi, J. Tsuchiya, Post-aragonite phase transformation in CaCO3 at 40 GPa, Am. Mineral. 90 (2005) 667–671], is believed to be a major carboncontaining mineral in the Earth’s mantle. Crystal structure of this mineral phase could not be solved using experimental data or traditional theoretical...

Experimental modeling of ankerite–pyrite interaction was carried out on a multi-anvil high-pressure apparatus “split sphere” type (6.3 GPa, 1050–1550 °C, 20–60 h). At T ? 1250 the formation pyrrhotite, dolomite, magnesite, and metastable graphite established. higher temperatures, generation two immiscible melts (carbonate sulfide ones), as well crystallization diamond growth seeds, occurred. It...

Coal, in particular, and fossil fuels, in general, are well positioned to supply the world’s energy needs for centuries to come if the environmental challenges associated with anthropogenic carbon dioxide emissions can be overcome. Carbon dioxide sequestration is being actively pursued as an option to reduce CO2 emissions, while still enjoying the advantages of low-cost fossil fuel energy. Mine...
