Methods of determine of parameters of systems take samples

Now methods of determine of parameters of systems take samples based on practical experience of investigation and operation of deposits are applied basically. Quantitative methods have the limited application. Being based on theories of geochemical fields, quantitative methods can be subdivided into three groups: 1) the methods based on the account of amplitude characteristics of geological fields (analytical method, method of V.V. Bogatsky, a method which is based the theory of the information); 2) the methods based on the account of parameters, describing simultaneously both amplitude and frequency (the method of variagrams and the method of standardize correlation function); 3) the methods based on the account of frequency characteristics (P.L. Kallistov method, method of geometrical autocorrelation). Principal defect of the first group of methods consists that they do not consider spatial variability of geochemical fields. Application of second group of methods is limited by a condition of stationary initial realizations. The certain defect also is inherent in the third group. Trustworthiness of the method of P.L. Kallistov depends on a reference mark (position of the first sample). The method of geometrical autocorrelation is freer from noted defects. From the theory of geochemical fields follows that the system of take a samples must calculation on the basis of frequency characteristics of fields. The amplitude characteristic has no direct attitude to a choice of an optimum step between samples.
