The geological theory of the origin of nodular flint in chalk beds contains a number of suppositions but still fails to provide a fully self-consistent explanation of all the observed features of flint. This brief paper proposes an alternative suggestion whereby flint is formed directly from chalk by the Kervran Effect, i.e. by a biological transmutation of atoms of calcium to atoms of silicon and oxygen. A corollary of this hypothesis is that the flint cortex is the site of the former biological activity, which offers the possibility of checking the hypothesis by analysis of undisturbed flint nodules.
The Beckmann model is considered in relation to both the Electric Universe perspective of a charged Earth and to the actual non-null results of the various Michelson-Morley-type experiments. It is demonstrated that the Beckmann model is consistent with both concepts. Furthermore, application of the Beckmann model to an orbiting charged Earth offers support to the interpretation of the non-null Michelson-Morley results as evidence not of an 'ether wind' but rather of an electromagnetically-induced directionally-dependent anisotropy of the speed of light. This hypothesis offers a new direction for research and possible re-analysis of existing data.
