摘要
通过对成矿成晕过程物质和能量转化的热力学分析和研究,从信息的本质上探讨了熵变、(火用)变和信息量的关系;将工程热力学函数(火用)引入成矿成晕过程的研究,提出了成矿完晕(火用)的概念,试将其作为成矿信息的能量指标,推导出了成矿成晕体系有关微量组分的成矿成晕(火用)的一般表达式为从原生晕到次生晕,初步建立了(火用)法评价地球化学异常的原则方法,并试图开发和利用此种成矿成晕信息于化探找矿和地质研究等领域中。
Through a thermodynamic analysis and study of matter and energy conversion in the ore-forming and halo-forming process, the paper discusses the relationship between entropy change, exergy change and information from the nature of information. The author introduces the engineering thermodynamic function, exergy, to the study of the ore-forming and halo-forming process, proposes concepts of ore-forming exergy and halo-forming exergy, and extends them from the study of primary to the study of secondary halos. In the paper a general expression of ore-forming and halo-forming exergy of trace elements in the ore-forming and halo-forming system is given asThe principle and method for assessing geochemical anomalies by the exergy method have been established, and an attempt has been made to develop and apply the ore-forming and halo-forming information to geochemical exploration for ore deposits.
