Abstract
An algorithm for identifying derivatives of potentially ore-bearing magmas among Precambrian rocks of tonalite–trondhjemite–granodiorite associations (TTGAs) is elaborated and tested using current genetic models. The algorithm is a succession of geochemical criteria for identifying the genesis of source of matters and, as a result, the melt products of geochemical reservoirs enriched in Au and other ore elements. This algorithm (a set of geochemical criteria of the ore potential) can be used for metallogenic zoning of the territories composed of TTGA rocks within ancient cratons.
