Electrical Conductivity and Sound Velocities of Talc under High Pressure and High Temperature Conditions

This dataset contains the ultrasonic and electrical data from the study entitled “Electrical Conductivity and Sound Velocities of Talc under High Pressure and High Temperature Conditions: Application to the Subducting Cocos Plate” by Hao et al., published in JGR-Solid Earth.
Acoustic measurements were conducted using ultrasonic interferometry in a Paris-Edinburgh press at pressures up to 3.4 GPa and temperatures up to 873 K on natural talc aggregate with different crystallographic orientations. In the spreadsheet, acoustic experiments correspond to tabs A1, A2, A3, and A4 (1 tab per experiment). In each tab, pressure, temperature, travel distance, travel time, and compressional wave velocities are listed for each measurement.
Electrical measurements on talc samples from the same starting material were performed at pressures of 1.5, 2.5, 3.5, and 6.0 GPa and temperatures up to 1264 K, using impedance spectroscopy in a multi-anvil press. In the spreadsheet, electrical experiments correspond to tabs BBC46, 47, 48, 49, 53, 55, and 56 (1 tab per experiment). In each tab, pressure, temperature, sample thickness, bulk electrical resistance, and electrical conductivity are listed for each measurement.

本数据集汇集了《JGR-Solid Earth》期刊中郝等作者发表的题为《在高压与高温条件下滑石的电导率和声速研究：对可可板块下潜应用的探讨》一文中所提及的超声波与电学数据。研究采用超声波干涉测量法，在巴黎-爱丁堡压力机中，对具有不同晶体取向的自然滑石聚集物，在最高压力达3.4 GPa和最高温度达873 K的条件下进行声学测量。在电子表格中，声学实验对应于标签A1、A2、A3和A4（每个实验对应一个标签）。每个标签中列出了每项测量的压力、温度、传播距离、传播时间和压缩波速度。对同一种起始材料的滑石样品进行的电学测量，在压力为1.5、2.5、3.5和6.0 GPa以及最高温度达1264 K的条件下进行，采用阻抗光谱法在多砧压力机中进行。在电子表格中，电学实验对应于标签BBC46、47、48、49、53、55和56（每个实验对应一个标签）。每个标签中列出了每项测量的压力、温度、样品厚度、体积电阻率和电导率。
