The deep carbon cycle and melting in Earth's interior
R Dasgupta, MM Hirschmann - Earth and Planetary Science Letters, 2010 - Elsevier
Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes
associated with deep cycle are in the order of 1012–13gC/yr and 1022–23g C, respectively …

The structure of iron in Earth's inner core
Earth's solid inner core is mainly composed of iron (Fe). Because the relevant ultrahigh
pressure and temperature conditions are difficult to produce experimentally, the preferred …

Composition and state of the core
The composition and state of Earth's core, located deeper than 2,900 km from the surface,
remain largely uncertain. Recent static experiments on iron and alloys performed up to inner …

Mineralogy of the lower mantle: A review of 'super-deep'mineral inclusions in diamond
F Kaminsky - Earth-Science Reviews, 2012 - Elsevier
Starting from the late 1980s, several groups of lower-mantle mineral inclusions in diamond
have been found. Three associations were established among them: juvenile ultramafic …
