J. Marvin Herndon (born 1944) is an American interdisciplinary scientist, who earned his BA degree in physics in 1970 from the University of California, San Diego and his Ph.D. degree in nuclear chemistry in 1974 from Texas A&M University.〔Current Biography 64: 45-49, 2003, http://web.archive.org/web/20050205193822/http://nuclearplanet.com/profile.htm, similar link: (J. Marvin Herndon's Brief Biography ) at January 12, 2013〕 For three years, J. Marvin Herndon was a post-doctoral assistant to Hans Suess and Harold C. Urey in geochemistry and cosmochemistry at the University of California, San Diego. He is the President of Transdyne Corporation in San Diego, California. He has been profiled in ''Current Biography'', and dubbed a “maverick geophysicist” by ''The Washington Post''.〔Guy Gugliotta. (Is Earth's Core a Nuclear Fission Reactor? ), ''The Washington Post'', March 24, 2003, p. A06〕 He suggested that the composition of the inner core of Earth is nickel silicide; the conventional view is that it is iron–nickel alloy〔Herndon, J. M. (1979) The nickel silicide inner core of the Earth. Proc. R. Soc. Lond. A368, 495-500.〕 More recently, he has suggested "georeactor" planetocentric nuclear fission reactors as energy sources for the gas giant outer planets.〔Herndon, J. M. (1992) ''Nuclear fission reactors as energy sources for the giant outer planets'', Naturwissenschaften 79, 7-14.〕 as the energy source and production mechanism for the geomagnetic field 〔Herndon, J. M. (2007) Nuclear georeactor generation of Earth’s geomagnetic field. Current Science, V. 93, No. 11, 1485-1487.〕 and stellar ignition by nuclear fission.〔Herndon, J. M. (1994) Planetary and protostellar nuclear fission: Implications for planetary change, stellar ignition and dark matter. Proc. Roy. Soc. Lond., A455, 453-461.〕 In 2005 Herndon postulated what he calls whole-earth decompression dynamics, which he describes as a unified theory combining elements of plate tectonics and Earth expansion. He suggests that Earth formed from a Jupiter-sized gas giant by catastrophic loss of its gaseous atmosphere with subsequent decompression and expansion of the rocky remnant planet resulting in ''decompression cracks'' at continental margins which are filled in by basalts from mid-ocean ridges.〔J. Marvin Herndon, ''Whole-earth decompression dynamics,'' Current Science, V. 89, No. 11, 10 Dec. 2005〕 Recent measuments of "geoneutrino" fluxes in the KamLAND and Borexino experiments have falsified Herndon's "georeactor" hypothesis on the presence of an active nuclear fission reactor in the Earth's inner core. == Publications == *Herndon, J.
