We report on an introductory study of this type using stream sediment data obtained during the “Nordkalott Project” B viken et al. We conclude that the variogram shapes for these elements are in agreement with fractal scaling of the data.
Geochemical Atlas of Fin- land: This dimension was found to exist between 5 and km, which are the limits set by the sampling distance and the size of the survey area. For each point on the grid we solved the Kriging equations, fratcals all measured concentrations fractqls a circle o f 50 km. This discrepancy is, however, not real for two reasons: These are typical properties of fractal objects – – they have a fractal dimension.

Normalized semi-variograms dots for 10 acid soluble elements in the minus 0. Data from distribution patterns of acid soluble A1 in stream sediment from northern Fennoscandia.
This type of systematic survey employ- ing the principles of fractal geometry for stepwise selection and progressively more thorough exami- nation of subareas of decreasing size, would apply to any survey area of interest and could improve cost-efficiency in mineral exploration. The previous remarks regarding adjustment to the sensitivity of the an- alytical method, as frachals as the requirement for interpolation between data points for the area-perimeter relation, are also valid in this case.
The length L of the coast of Norway as a function of the yardstick 5 used in the measurements.

Log-normal distributions have a great range of concentrations and only variations in high concentrations will contribute sig- nificantly to the sum of the variance of increments; although the relative vari- ation may be great at low concentrations.

However, the “ideal” semivariogram Fig. Those who would like a more in-depth treatment of these subjects are referred to the rapidly increasing literature on fractals see for example Feder, and Scholz and Mandelbrot, The n u m b e r of steps needed to go from one end to the other, always stepping on the coastline, is N 5o.

Large provinces of ele- vated trace element contents may have a higher frequency of significant min- eral deposits than geochemical background regions.

Lateral distribution of platinum group elements in drill holes from basal and foot wall zones of the Minneapolis Adit, Stillwater, Montana. If you are a registered author of this item, you may also want to check the “citations” tab in your RePEc Fdactals Service profile, as there may be some citations waiting for confirmation. Last but not least, we are all grateful to Jens for not having allowed undue personal modesty to deprive us of accounts of his own group’s varied and excellent work.
