WHAT WILL THE DEEP DRILLING AT SILJAN, SWEDEN, PROVE?

The following highly-topical contribution is concerned with the experimental deep-drilling programme which has been initiated in the Siljan Ring in Sweden. Readers will recall that according to the theories of Professor Thomas Gold of Cornell University, which were first propounded in our January 1979 issue ( 1(3), 3-19), deep-seated abiogenic hydrocarbon gases may be encountered at this site, where a meteoric impact is believed to have produced a structure favourable for hydrocarbon accumulation. Dr Gibbs, however, here suggests an alternative, more conventional explanation for any hydrocarbon gases that may be found as drilling, which commenced in June 1986, progresses.
