Abstract
A method of geochemical prospecting for buried sulphur mineralization which comprises collecting relatively organic free soil samples and determining the carbon isotope composition of the carbonate fraction.
Claims7
A method of geochemical prospecting for buried sulphur mineralization which comprises:
- (a) collecting at least one soil sample from a depth beneath the zone of high plant and organic matter contribution to the composite soil;
- (b) generating carbon dioxide gas from the carbon in the carbonate fraction of said soil sample;
- and,
- (c) analysing the proportion of carbonate carbon-12 and carbonate carbon-13 in said carbon dioxide gas to determine the presence of buried sulphur mineralization.
