Raw Ground Survey Total Magnetic Intensity Data from the North Abaya Geothermal Field, Southern Central Main Ethiopian Rift

3. Dataset Description 3.1 Overview This dataset contains raw ground-based total magnetic intensity (TMI) measurements collected during a systematic geophysical field survey of the North Abaya geothermal area in the Main Ethiopian Rift (MER), Ethiopia. The survey was designed to characterize the structural controls on geothermal fluid circulation and to delineate subsurface geological features including faults, intrusive bodies, and hydrothermal alteration zones that govern reservoir potential in the region. The data are provided in their raw, unprocessed form as recorded in the field, without the application of diurnal corrections, reduction to the pole (RTP), or other geophysical data enhancements. This ensures full reproducibility and allows end users to apply processing workflows appropriate to their analytical objectives.3. 数据集描述 3.1 概述 本数据集包含在埃塞俄比亚境内埃塞俄比亚主裂谷（Main Ethiopian Rift, MER）北阿巴亚地热区开展的系统性地球物理野外勘测中采集的原始地面实测总磁场强度（Total Magnetic Intensity, TMI）测量数据。本次勘测旨在厘清地热流体循环的结构控制要素，并刻画区域内管控地热储层潜力的地下地质特征，涵盖断层、侵入岩体与热液蚀变带。 本次提供的数据为野外原始记录的未处理格式，未施加日变校正（diurnal corrections）、化极（Reduction to the Pole, RTP）或其他地球物理数据增强处理。此举可保障数据的完全可复现性，同时允许终端用户根据自身分析目标选用适配的处理工作流。
