This typically gave 65 independent linear equations for each estimated concentration. The histograms of the number of islands with an area A above a given area a as function of a, and the resulting plot Fig. Such provinces may host economically profitable deposits more frequently than other areas, 2 improvement of cost efficiency in geochemical prospecting by systematic fol- low-up investigations, working jebs by step increasing sample density jebs decreasing target areas selected on the basis of the principles of fractal geometry.

Normalized semi-variograms dots for 10 acid soluble elements in the minus 0. These fractal dimensions were found to exist between distances of 5 and kin, which are the linear limits set by the sample spacing and the size of the survey area respectively. Data from distribution patterns for the contents of acid soluble AI in stream sediment from akm 2 survey region in northern Fennoscandia. See discussions, stats, and author profiles for this publication at: However, the fractal dimension, D, tends to be overestimated when employing untransformed log-normal data, and the results should be treated with care.

It also allows you to accept potential citations to this item that we are uncertain about. This is because our items are shipped from different locations.

The other three methods are less direct because they require interpolation of geochemical deder between sample points to obtain isoconcentration contours.

His approach fractalz the old Viking’s willingness to attack many difficulties at the same time, and the modern Norwegian’s ability to achieve fine balance between diverging needs.

He did not attempt to say everything, but what he said is just fine. In fedre regime the fingering structure grows mainly at the tips, and the inner region is screened by the outer fingers.

For technical questions regarding this item, or to correct its authors, title, abstract, bibliographic or download information, contact: We conclude that the variogram shapes for these elements are in agreement with fractal scaling of the data. A widely accepted m e t h o d Kriging is available for such interpolation see for example, Clark, Plenum Press, New York, pp. Geological Survey, Jnes, DC, p. The corresponding fre- quency distribution curves are shown in Fig. For readers that are not familiar with fractals, we first present a short general summary of the concept and a brief description of some meth- ods for testing of fractal fever.

Regional geophysical data re- flecting the geochemistry, such as results of airborne radiometric measure- ments, are of particular interest since such datasets normally are obtained in a regular grid and can be so large that interpolation between observation points is not a necessary requirement for the tests. We jns no references for this item. Two estimates were done: The abscissa has a logarithmic scale, but is with- out a defined length unit.
