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.

摘要—

使用当前的遗传模型，详细阐述和测试了一种算法，该算法可识别和识别斜方晶石-长风白铁矿-花岗岩闪长岩协会（TTGA）的前寒武纪岩石中潜在的含矿岩浆衍生物。该算法是一系列地球化学标准，可用于确定物质来源的成因，从而确定富含金和其他矿石元素的地球化学储层的熔体产物。该算法（一套矿石潜力的地球化学标准）可用于对古克拉通内TTGA岩石组成的地区进行成矿区划。
