Abstract
THE METHOD AND AIMS OF STUDIES ON VARIABILITY OF DEPOSITS PARAMETERS
Summary
Description of variability of deposit parameters is made on the basis of a deterministic, probabilistic or mixed model. Deterministic model assumes a relationship between parameters value and position of observation points. Probabilistic model accepts random parameters deviations. Mixed model assumes that on the basis of casual deviations it is possible to observe systematic, non-random changes of values of parameters. They may be oriented or periodic. Separation of non-random variability component from the background of random deviations is made by means of mean-moving trend, correlation and spectral analyses. Basic principles of the methodology of determination of reconaissance network in relation to variation of deposits parameters and possibilities of utilization of various studies for solving problems of genesis of deposits are discussed. The discussion is illustrated by the results• of studies on sulphur deposits.
