As Pointed out by Boyle (1974) in his comprehensivecoverage of element associations of mineral deposits, rarely does a single element concentrate in the Earth's crust• to form a mineral deposit. Generally mineral deposits consist of a suite of elements which have been concentrated because of certain intrinsic chemical properties which depend esse…
Published multi-element stream-sediment exploration geochemical data from new brunswick are used to illustrate some pitfalls of correlation and regression. Large matrics of correlation coefficients. are easly mass-produced.These coefficient are susceptible to suprious values, clustering of samples and the effect of other variables on the relation un…
This report covers my activities from August 2 to November 5,1972, in geochemical exploration as a part of the U. S. Geological Survey (USGS) program in cooperation with the Geological Survey of Indonesia (GS!) sponsored by the Government of Indonesia and the Agency for International Development (AID) under Participating Agency• Agreelll…
One of the most important aspects of the interpretation of geochemical data is the choice ofanomaleus values from among these data. Disticuvely anomalous values are readily diseriminated, because they are characterized by statistical methods. Applications of these methods are described in the present paper.
