Brittle faults and fault zones are important fluid flow conduits through the upper part of Earth's crust that are involved in many well-known phenomena (e.g. earthquakes, thermal water and gas transport, or water leakage to underground tunnels). The permeability property, or the ability of porous materials to conduct water and gas, is one of the key parameters required in understanding and predicting fluid flow. Although close to a thousand studies have been done, and permeability tested in parts of fault zones, a sytematic summary and database is lacking. This data descriptor is for a multi-disciplinary world-wide compilation and review of bulk and matrix permeability of fault zones: 410 datasets, 521 reviewed sites, 379 locations, >10000 publications searched. The review covers studies of faulting processes, geothermal engineering, radioactive waste repositories, groundwater resources, petroleum reservoirs, and underground engineering projects. The objectives are to stimulate the cross-disciplinary data sharing and communication about fault zone hydrogeology, document the biases and strategies for testing of fault zones, and provide the basic statistics of permeability values for models that require these parameters.
脆性断层和断层带是地球地壳上部重要的流体流动通道，它们与许多著名现象有关（例如地震、热液和气体传输，或水泄漏到地下隧道）。渗透率特性，即多孔材料输送水和气体的能力，是理解和预测流体流动所需的关键参数之一。尽管已经进行了近千项研究，并对断层带的部分区域进行了渗透率测试，但仍缺乏系统的总结和数据库。这个数据描述符是对断层带整体和基质渗透率的多学科、全球性综合和审查：410 个数据集，521 个审查点，379 个地点，搜索了超过 10000 篇出版物。该综述涵盖了断层过程、地热工程、放射性废物处置库、地下水资源、石油储层和地下工程等方面的研究。目的是促进关于断层带水文地质学的跨学科数据共享和交流，记录断层带测试的偏差和策略，并为需要这些参数的模型提供渗透率值的基本统计信息。
