地球表面系统中的纳米粒子(NPs)因其异常效应及其在环境修复和资源勘探中的科学意义和应用价值而受到全球的关注。通过比较和综合研究，总结了纳米颗粒特征检测技术的发展及其比较，总结了典型纳米颗粒的特征，包括纳米级矿物、纳米有机物、天然金属纳米颗粒、纳米包裹体以及土壤和水中的纳米颗粒，揭示了纳米颗粒的物理、化学、微生物和多地质来源；(4)阐述了纳米粒子的大小、迁移、聚集、吸附效应和氧化还原活性等异常性质，认为纳米粒子在地表系统中的形成、迁移、沉积和积累与环境演化和资源富集度密切相关，具有环境效应和资源效应。在此基础上，阐明了NPs在环境修复和资源勘探中的应用：(1)分析了NPs和改性NPs的用途以及NPs与其他修复技术的组合，考察了影响修复效果的主要因素，如土壤特性、有害元素种类和NPs本身；(2)来自深成流体和风化作用的NPs可以指示成矿机理，指导隐伏矿床的识别。在油气勘探中，有机NPs可以反映油气生成过程，确定油气赋存状态。有机纳米颗粒也广泛参与金属元素的成矿过程，可以反映出有机质与金属共存的特征。
Nanoparticles (NPs) in the Earth surface systems have been a global concern due to their abnormal effects and their scientific significance and application value in environmental remediation and resource exploration. By means of comparative and comprehensive studies: (1) A description of the development of techniques for detecting NP characteristics and comparisons between those techniques are summarized; (2) the characters of typical NPs, including minerals at the nanoscale, nano organic matter, natural metal NPs, nanoinclusions, and NPs in soil and water are concluded; (3) the physical, chemical, microbial, and multigeological origins of NPs are revealed; and (4) the abnormal properties of NPs including the size, migration, aggregation, and adsorption effects and oxidation–reduction reactivity, are elaborated upon.The formation, migration, deposition, and accumulation of NPs in the Earth surface system are closely related to the environment evolution and resource enrichment, and therefore NPs have environment and resource effects. On this basis, the uses of NPs in environmental remediation and resource exploration are clarified: (1) uses of NPs and modified NPs and combinations of NPs and other remediation technologies are analyzed, and the main factors influencing the remediation effect, such as the soil characteristics, hazardous element species, and NPs themselves, are examined; (2) NPs originating from plutonic fluid and weathering can indicate the mineralizing mechanism and instruct the identification of concealed deposits. For gas and oil exploration, organic NPs can reflect hydrocarbon-generating processes and determine gas and oil occurrence states. Organic NPs are also widely involved in the mineralization process of metal elements and thus can indicate the coexistence characters of organic matter and metal.
