Geothermal Project on TU Delft Campus - DAPGEO-02 Core CT-Scan Data

This dataset contains the CT-scan data of rock cores collected from the DAPGEO-02 research borehole, one of the monitoring boreholes of the geothermal project on TU Delft Campus. Complemetary data and information about the cores are published in Geothermal Project on TU Delft Campus - DAPGEO-02 Initial Borehole Dataset and in the final drilling report. Cores from the Maassluis Formation and Paleogene clay formations were scanned at TU Delft using a macro CT-scanner (Siemens Somatom Volume Zoom CT scanner). The cores were scanned in plastic liner using a slice resolution of 0.6mm. Core length is of about 1 m, which gave 1600 slices per scan. Data was processed according to the normal procedure using the standard gray scale settings of medical scanners of -1000 HU tot +3000 HU. Processed CT-scan vertical cross-section images are also included as an overview.

本数据集包含从DAPGEO-02研究钻孔采集的岩芯计算机断层扫描（CT-scan）数据，该钻孔是代尔夫特理工大学（TU Delft）校区地热项目的监测钻孔之一。有关该岩芯的补充数据与相关信息，已发表于《代尔夫特理工大学校区地热项目——DAPGEO-02初始钻孔数据集》及最终钻探报告中。取自马斯卢伊斯地层（Maassluis Formation）与古近纪黏土地层的岩芯，于代尔夫特理工大学使用宏观计算机断层扫描仪（Siemens Somatom Volume Zoom CT扫描仪）完成扫描。扫描时岩芯置于塑料衬管内，切片分辨率为0.6毫米。单根岩芯长度约为1米，单次扫描可获得1600张切片图像。数据按照标准流程进行处理，采用医用扫描仪的标准灰度设置，灰度范围为-1000 HU至+3000 HU。本次数据集还附带经过处理的计算机断层扫描垂直横截面图像，作为概览内容。
