This review aims to bridge the knowledge gap between geological and geophysical communities by elucidating the interpretation of aeromagnetic data. Aeromagnetic surveys measure the Earth's magnetic field variations and provide critical insights into subsurface geology, including basins, stratigraphy, igneous rocks and structural geology. The magnetic properties of rocks make these datasets valuable for identifying anomalies associated with various rock types and their magnetic responses. However, interpreting aeromagnetic data is complex due to the diverse geological processes that influence the formation and distribution of magnetic minerals, which must then be correlated with geological phenomena and features. Despite improved data accessibility and processing, many geoscientists still find interpreting aeromagnetic data challenging, resulting in a shortage of skilled expertise for research and industry applications. Accurate interpretation necessitates a thorough understanding of data collection and processing, recognising both the insights and limitations of the methods used and understanding how data resolution impacts the scale of interpretable geological features. This review is intended to assist those grappling with these challenges and to aid the geophysical community in interpreting complex geological features.

来自航磁数据的地质学


本综述旨在通过阐明航磁数据的解释来弥合地质和地球物理社区之间的知识差距。航空磁力勘测可以测量地球的磁场变化，并提供对地下地质学的重要见解，包括盆地、地层学、火成岩和构造地质学。岩石的磁性使这些数据集对于识别与各种岩石类型相关的异常及其磁响应很有价值。然而，由于影响磁性矿物形成和分布的地质过程多种多样，因此解释航磁数据很复杂，因此必须与地质现象和特征相关联。尽管数据可访问性和处理能力有所提高，但许多地球科学家仍然发现解释航磁数据具有挑战性，导致研究和工业应用缺乏熟练的专业知识。准确的解释需要对数据收集和处理有透彻的了解，认识到所用方法的洞察力和局限性，并了解数据分辨率如何影响可解释地质特征的规模。本综述旨在帮助那些努力应对这些挑战的人，并帮助地球物理界解释复杂的地质特征。
