Abstract

The results of the study of anomalous structures of geochemical fields (ASGF) accompanying hydrothermal gold deposits are considered. A model of the formation of such structures in the course of development of hydrothermal ore-metasomatic systems is proposed. The existing methods of detection and geometrization of ASGF are evaluated. The elaborated technique of the study of anomalous geochemical fields is based on standardized unbiased indexes assigned to detection and geometrization of anomalous structures. A classification of ASGF at hydrothermal gold deposits has been developed. General features due to the universal mechanism of functioning of hydrothermal systems and specific features related to the localization and metallogenic specialization of particular kinds of ore mineralization are identified for the studied geological and economic types of gold deposits. The elaborated technique of quantitative characterization of ASGF parameters comprises the geometrization of anomalous structures, calculation of the coefficient of ordering, and computation of the productivities of standardized indexes of zoning. The established regular variation of quantitative parameters of ASGF with depth may be applied to the estimation of the erosion level of ore-bearing structural units in ore fields and deposits.
