为避免或减少目前物质来源分析中难以避免的主观性和片面性,有必要使物质来源分析向系统化、标准化、定量化发展。物质来源分析的依据不止一种,方法各异。对它们的标准化和定量化只能逐一研究,最终实现系统化。本文仅就其中之一进行讨论。由矿物鉴定获得的矿物组合(特别是重矿物组合)是物质来源分析中一种常用的依据。它和绝大多数的依据一样,只能是分析物质来源的必要依据,而不是充分依据。 In order to avoid or reduce the unavoidable subjectivity and one-sidedness in the current analysis of material sources, it is necessary to systematize, standardize and quantify the analysis of material sources. Material source analysis based on more than one method. The standardization and quantification of them can only be studied one by one, eventually achieving systematic. This article discusses only one of them. Mineral assemblages obtained from mineral identification (especially heavy mineral assemblages) are a common source of material source analysis. Like most of the evidence, it can only be a necessary basis for analyzing the source of a substance, not a sufficient basis.
