Dataset for: Temperature Dependence of Fault Frictional Healing in Quartz Gouges at Hydrothermal Conditions

This files are data relative to hydrothermal friction experiments conducted on quartz gouges, supporting the study "Temperature Dependence of Fault Frictional Healing in Quartz Gouges at Hydrothermal Conditions". This dataset contains raw data from hydrothermal friction experiments performed on simulated quartz gouges using a rotary shear apparatus "RoSA" equipped with a hydrothermal pressure vessel "HYDROS", installed in the Rock Mechanics Laboratory of the Department of Geosciences, Padua University. The experiments consist of slide–hold–slide tests designed to quantify fault frictional healing under controlled temperature, stress, and pore-fluid conditions. Quartz gouges with different initial grain sizes were sheared over large slip distances (up to ~90 mm) at temperatures of 23, 100, 200, and 400 °C, pore fluid pressures of 6 and 36 MPa, and effective normal stresses of 10 and 20 MPa. Experiments explore the combined effects of temperature, finite strain, effective stress, and fluid state (liquid, vapor, and supercritical) on frictional behavior and healing. The CSV files include time series of mechanical variables such as shear torque, normal stress, angular rotations, sangular velocities, fluid pressure, and temperature. Information on how to convert these measurements into geologically meaningful quantities can be found in the manuscript and references therein.本数据集为石英断层泥（quartz gouge）热液摩擦实验的相关数据，支撑论文"热液条件下石英断层泥断层摩擦愈合的温度依赖性"的研究工作。 本数据集包含模拟石英断层泥的热液摩擦实验原始数据，实验采用帕多瓦大学地球科学系岩石力学实验室安装的、配备热液压力容器"HYDROS"的旋转剪切装置"RoSA"完成。 本次实验采用滑移-静置-滑移（slide–hold–slide）测试方法，旨在量化受控温度、应力及孔隙流体条件下的断层摩擦愈合效应。 实验选用不同初始粒径的石英断层泥，在温度23、100、200及400 ℃、孔隙流体压力6与36 MPa、有效正应力10与20 MPa的条件下开展最大滑移距离约90 mm的剪切实验，探究温度、有限应变、有效应力及流体状态（液态、气态与超临界态）对摩擦行为与愈合效应的综合影响。 本数据集的CSV格式文件包含剪切扭矩、正应力、角位移、角速度、流体压力及温度等力学变量的时间序列数据。将上述测量数据转换为具有地质意义的物理量的方法，可参见该研究论文及其中引用的参考文献。
