土壤(土被)中后生异常与深穿透地球化学

Epigenetic anomaly in soil or regolith and deep-penetrating geochemistry

本文论述了土壤定义、土壤中同生组分和后生组分,重点论述了后生异常,特别是上置后生异常。提出深穿透化探技术设计原理是提取土壤中来自深部与矿化有关的后生组分,而尽可能不破坏或少破坏土壤基体(同生组分)。用实例说明同生异常和后生异常特征,为什么常规化探(全量)难以在运积物覆盖区隐伏矿勘查中发挥作用的原因。从提取土壤后生异常角度,分析了各种深穿透技术历史、现状和存在问题。

Syngeneic and epigenetic components in soil or regolith were discussed from definition.Epigenetic anomalies were classified as lateral and top anomalies,and top epigenetic anomalies are the base for deep penetration technology design.The principle of deep penetrating geochemical exploration technology is to extract the epigenetic components related to deep mineralization without destroying or less destroying the soil matrix(syngeneic components).The authors use a case study to illustrate what the epigenetic anomalies are and why conventional geochemical exploration(total)cannot be used for mineral exploration in overburden areas.From the perspective of extracting epigenetic anomalies in soil,the history,updates and problems of various deep penetration technologies are analyzed.
