异常评价,是化探工作的重要研究课题.矿区化探详查的主要内容是:从大量化探异常中很快地筛选出有经济意义的异常,分辨矿与分散矿化,分辨矿化类型和判断矿体剥蚀程度等.本文就个人的一些体会作一简介. 区分矿与分散矿化区分有经济价值的矿化与分散矿化是比较困难的,因为有经济价值的矿床是按目前的选冶技术水平和国民经济需要确定的,它与分散矿化之间并无长期不变的界限.现在认为是分散矿化,随着选冶技术水平的提高,将来可能成为有经济价值的矿床.尽管如此,仍有些方法可用来区分矿与分散矿化.根据实践中的尝试,提出如下几种方法.
Anomaly evaluation is an important research topic of geochemical exploration work.The main contents of the detailed exploration of the geochemical exploration in the mining area are as follows: rapidly anomalies with economic significance are screened out from a large number of geochemical anomalies, and the types of mineralization, mineralization and mineralization And to determine the degree of denudation of the ore body, etc. This article makes a brief introduction of some personal experiences.It is difficult to distinguish between mineralization and decentralized mineralization, which have economic value of mineralization and decentralized mineralization, because the economic value of the deposit is based on the current There is no long-term limit to the level of metallurgical and metallurgical technologies and national economy, and there is no long-term boundary between them and decentralized mineralization, which is now considered as decentralized and mineralized. As the level of metallurgical and metallurgy technologies rises, it may become an economically valuable deposit in the future In spite of this, there are still some methods that can be used to distinguish between mineralization and disperse mineralization. According to the practice, several methods are proposed.
