Large gem diamonds from metallic liquid in Earth's deep mantle

EM Smith, SB Shirey, F Nestola, ES Bullock, J Wang… - Science, 2016‏ - science.org
The redox state of Earth's convecting mantle, masked by the lithospheric plates and basaltic
magmatism of plate tectonics, is a key unknown in the evolutionary history of our planet …

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 …

Native iron reduces CO2 to intermediates and end-products of the acetyl-CoA pathway

SJ Varma, KB Muchowska, P Chatelain… - Nature Ecology & …, 2018‏ - nature.com
Autotrophic theories for the origin of life propose that CO2 was the carbon source for
primordial biosynthesis. Among the six known CO2 fixation pathways in nature, the acetyl …
