KTB Borehole Measurements Data Geochemical Logs (GLT) Extensive borehole measurements were performed during the active drilling phase of the KTB pilot and main hole. All KTB borehole measurements are described in detail in the Scientific Technical Report - Data 21/03 "KTB Borehole Logging Data" (Kück et al. 2021). Please read it thoroughly to avoid inappropriate or wrong use of the data. The KTB borehole measurement data files contain the final processed versions of logging data from the two KTB boreholes: • KTB-Oberpfalz VB (KTB Vorbohrung/Pilot Hole or KTB-VB) • KTB-Oberpfalz HB (KTB Hauptbohrung/Main Hole or KTB-HB). Here only the acronyms KTB-VB and KTB-HB are used. In total there are 145 data files from the KTB-VB and 239 data files from the KTB-HB. All logs were run in open hole unless noted otherwise (see the file header). The maximum logging depth was 4001 m in the KTB-VB and 9085 m in the KTB-HB. The files of the Geochemical Logs contain data from measurements made with the Schlumberger GLT sonde. This sonde was a combination of several passive and active nuclear tools yielding the relative abundances of nine elements. The geochemical logs are depth corrected to the reference GR (see Composite Logs) of the respective borehole. The data are provided in ASCII format. Detailed descriptions are provided in the associated data report (STR 21/03, Kueck et al., 2021) and the KTB Borehole Measurements Catalog. Acknkowledgements: The GFZ German Research Centre for Geosciences, Potsdam, Germany, as successor of the KTB Project Management provides the logging data, which were obtained under grants RG8604, RG8803 and RG 9001 of the Federal Ministry of Research and Technology of Germany.
