Molten Earth? 1


For more than two centuries, textbooks have taught that the early Earth was molten for 500,000,000 years, because it formed by meteoritic bombardment (a). If so, the heat released by the impacts would have melted the entire Earth many times over (b). Had Earth ever been molten, dense, nonreactive chemical elements such as gold would have sunk to Earth’s core. Gold is 70% denser than lead, yet is found at the Earth’s surface (c).


a. “The textbook view that the earth spent its first half a billion years drenched in magma could be wrong.” John W. Valley, “A Cool Early Earth?” Scientific American, Vol. 294, October 2005, p. 59.


b. “The kinetic energy (~5 x 10^38 ergs) released in the largest impacts (1.5 x 10^27 g at  9 km/sec) would be several times greater than that required to melt the entire Earth.” George W. Wetherill, “Occurrence of Giant Impacts during the Growth of the Terrestrial Planets,” Science, Vol. 228, 17 May 1985, p. 879.


c. If gold were found only near volcanoes, then one might claim that gold was brought up to the Earth’s surface by volcanoes.  However, gold is seldom found near volcanoes.


Suppose that extremely hot water (932°F or 500°C) circulated under the crust—a crust that had never been molten. Gold in high concentrations would go into solution. If the solution then escaped to the Earth’s surface, most gold would precipitate as the water’s pressure dropped and temperature dropped. If this happened, about 250 cubic miles of water must have burst forth to account for the gold found in just one gold mining region in Canada. [See Robert Kerrich, “Nature’s Gold Factory,” Science, Vol. 284, 25 June 1999, pp. 2101–2102.]  If these ideal pressure-temperature conditions did not exist, even more water must come up faster to account for the Earth’s gold deposits. These are hardly the slow processes that evolutionists visualize. On pages 111–147 and 457–463, you will see how, why, and when vast amounts of hot water burst up through faults.


About 40% of all gold mined in the world is from the Witwatersrand Basin in South Africa. This gold, deposited in compressional fractures within the basin, precipitated from water whose temperature exceeded 300°C. [See A. C. Barnicoat et al., “Hydrothermal Gold Mineralization in the Witwatersrand Basin,” Nature, Vol. 386, 24 April 1997, pp. 820–824.]


About 40% of all gold mined in the world is from the Witwatersrand Basin in South Africa. This gold, deposited in compressional fractures throughout the basin, precipitated from water whose temperature exceeded 300°C. [See A. C. Barnicoat et al., “Hydrothermal Gold Mineralization in the Witwatersrand Basin,” Nature, Vol. 386, 24 April 1997, pp. 820–824.]
