A Hydrogen Rich Early Earth?

V.N. Larin (1993) [1] proposed that the chemical
differentiation in the solar system was driven by the magnetic
field of the Protosun, which induced a magnetic zoning of the
ionized solar nebula matter. This hypothesis is geochemically
supported by a correlation between the  Log of  the chemical
element abundances of the Earth outer geospheres relative to
the Sun, and the first ionization potential of these elements.
The observed correlation is theoretically reappraised in the
present paper and  is interpreted as a Boltzmann distribution,
which is proportional to the distance  to the Protosun.  The
model is succesfully tested for the observed solar normalized
chemical compositions of the Earth, Mars and chondrites;
poorly convincing results are obtained for Venus in absence of
reliable data for low abundance elements.
The comparison of the abundance of a given element in
the Earth’s crust with the average abundance predicted from
the proposed model is further interpreted as reflecting the
geochemical radial differentiation of the Earth. Using a simple
thermochemical model, we propose that the radial distribution
of hydrogen on Earth is a function of the chemical affinities of
major Earth forming elements with hydrogen.
This model provides insights for hydrogen abundance on
Earth. Notably, the inner Earth would  have been and still
could be hydrogen rich. Although most of this hydrogen have
escaped to atmosphere and space through the thorough
degassing of the mantle, it is reasonable to suggest, in the
perspective given by our model, that very large amounts still
reside in the core.

About Me

My photo

I started my career in 1979 as an IBM/370 system engineer. In 1986 I got my PhD. in Robotics at St. Petersburg Technical University (Russia) and then worked as a professor teaching there CAD/CAM, Robotics and Computer Science for about 12 years. I published 30 papers and made several presentations for international conferences related to the Robotics, Artificial Intelligent and Computer fields. In 1999 I moved to the US and worked at Capital One bank in Richmond as a Capacity Planner. My first CMG paper was written and presented in 2001. The next one, "Global and Application Level Exception Detection System Based on MASF Technique," won a Best Paper award at CMG 2002 and was presented again at UKCMG 2003 in Oxford, England. My CMG 2004 paper about applying MASF technique to mainframe performance data was republished in the IBM z/Series Expo. I also presented my papers in Central Europe CMG conference and in numerous US regional meetings. I continue to enhance my exception detection methodologies. After working more than 2 years as the Capacity Management team lead for IBM, I had worked for SunTrust Bank for 3 years and then got back to IBM holding for 2+ years  Sr. IT Architect position. Currently I work for Capital One bank as IT Manager for IT Capacity Management group. In 2015 I have been elected to the CMG ( board of directors,
