The Drilling the Ivrea-Verbano zonE (DIVE) project, run as ICDP expedition 5071, aims at studying the lower continental crust (LCC) towards and across the Moho transition zone. The study area provides unique access to a section of the LCC with well-preserved structural relationships. Two drilling targets were selected from this zone for scientific investigations, which, in combination, reveal significant aspects of its geologic history. The goals of the project are primarily petrological-geochemical, geophysical, structural, microbiological, and focusing on natural gases. Two boreholes have been successfully drilled in project DIVE 1: first 5071_1_B near Ornavasso in 2022, then 5071_1_A in Megolo in 2023-2024. This data publication provides the operational dataset of the ICDP project DIVE (ICDP 5071). The dataset is documented by the Explanatory Remarks (https://doi.org/10.48440/ICDP.5071.002).
This data set was collected in the frame of the ICDP drilling project DIVE (Drilling the Ivrea-Verbano ZonE) to determine the thermal properties of lower crustal lithologies and their variabilities. Two boreholes were drilled, the first 5071_1_B (in Ornavasso, final depth: 578.5 m) intersects the amphibolite-facies metasedimentary succession of the Ivrea-Verbano Zone, and the second borehole 5071_1_A (in Megolo, final depth: 909.5 m) is located within the mafic complex. Thermal properties were measured on fresh drill cores from the two DIVE boreholes and surface samples collected from nearby outcrops. The data set comprises thermal conductivity (TC), thermal diffusivity (TD), and specific heat capacity (Cp) measurements as well as measurements on concentrations of heat producing elements (HPE) Uranium (U), Thorium (Th), and Potassium (K) and the calculated radiogenic heat production (A).
The overarching goal of the Drilling Overdeepened Alpine Valleys (DOVE) project will be to date the age and extent of past glaciations. Formerly-glaciated areas are often characterized by deeply incised structures, often filled by Quaternary deposits. These buried troughs and valleys were formed by glacial overdeepening, likely caused by pressurized subglacial meltwater below warm-based glaciers. Results of this drilling campaign, supported by new dating technologies, will further provide critical data on 'how' and 'at which rate' glacial erosion affects such mountain ranges and their foreland. These processes are also of fundamental importance for evaluating the safety of radioactive waste disposal sites, which are planned in areas of former glaciations. Moreover, results of this project will fill gaps in the knowledge of paleoclimate and atmospheric circulation patterns during past glacial epochs and how these patterns affected ice build-up. The operational data sets include the drill core documentation from the mobile Drilling Information System (mDIS), full round core scans, MSCL data sets, a preliminary core description and the geophysical downhole logging data that were acquired during and subsequent to the drilling operations. All downhole logs and core depth were subject to depth correction to a common depth master (cf. operational report for detailed information). The data are described by two scientific reports, the Operational Report (https://doi.org/10.48440/ICDP.5068.001) and the Explanatory Remarks on the Operational Datasets (https://doi.org/10.48440/ICDP.5068.002).
The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project focuses on mountain building processes in a major mid-Paleozoic orogen in western Scandinavia and its comparison with modern analogues. The transport and emplacement of subduction-related highgrade continent-ocean transition (COT) complexes onto the Baltoscandian platform and their influence on the underlying allochthons and basement is being studied in a section provided by two fully cored 2.5 km deep drill holes. These operational data sets concern the second drill site, COSC-2 (boreholes ICDP 5054-2-A and 5054-2-B), drilled from mid April to early August 2020. COSC-2 is located approximately 20 km eastsoutheast of COSC-1, close to the southern shore of Lake Liten between Järpen and Mörsil in Jämtland, Sweden. COSC-2 drilling started at a tectonostratigraphic level slightly below that at COSC-1’s total depth. It has sampled the Lower Allochthon, the main Caledonian décollement and the underlying basement of the Fennoscandian Shield, including its Neoproterozoic and possibly older sedimentary cover. COSC-2 A reached 2276 m driller's depth with nearly 100 % core recovery between 100 m and total depth. COSC-2 B, with a driller’s depth of 116 m, covers the uppermost part of the section that was not cored in COSC-2 A. The operational data sets include the drill core documentation from the drilling information system (mDIS), full round core scans, MSCL data sets, a preliminary core description and the geophysical downhole logging data that were acquired during and subsequent to the drilling operations. All downhole logs and core depth were subject to depth correction to a common depth master (cf. operational report for detailed information). The COSC-2 drill core is archived at the Core Repository for Scientific Drilling at the Federal Institute for Geosciences and Natural Resources (BGR), Wilhelmstr. 25–30, 13593 Berlin (Spandau), Germany.
The 50 km long KTB Line 2 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects. The network of lines consists of two DEKORP profiles, DEKORP 4N and its appendix 4Q, and six shorter KTB profiles, KTB 8501 – 8506, arranged in the form of a grid parallel and perpendicular to the main tectonic lineaments. The purpose of the investigations was to explore the planned target area for the Continental Deep Drilling Site in the Upper Palatinate with high-fold near-vertical incidence vibroseis acquisition. The main focus was on the crustal structure of the central Mid-European Variscides down to the Moho and the uppermost mantle and, in particular, on the suture between the Moldanubian Zone and the northward adjacent Saxothuringian Zone as well as on the metamorphic Zone of Erbendorf-Vohenstrauss. The array of the KTB profiles represents the pre-cursor of the 3D seismic survey ISO 1989 (Integrated Seismics Oberpfalz). Details of the experiment, first results and interpretations were published by DEKORP Research Group (1987, 1988). Results discussed together with the drilling site were presented in a number of works which can be found in Emmermann & Wohlenberg (1989). The Technical Report of KTB 8502 gives complete information about acquisition and processing parameters. The European Variscides, extending from the French Central Massif to the East European Platform, originated during the collision between Gondwana and Baltica in the Late Palaeozoic. Due to involvement of various crustal blocks in the orogenesis, the mountain belt is subdivided into distinct zones. The external fold-and-thrust belts of the Rhenohercynian and Saxothuringian as well as the predominantly crystalline body of the Moldanubian dominate the central European segment of the Variscides. Polyphase tectonic deformation, magmatism and metamorphic processes led to a complex interlinking between the units. The Saxothuringian represents the infill of a Cambro-Ordovician basin. The Moldanubian contains blocks of pre-Variscan crust and their Palaezoic cover. During the Variscan orogeny the Moldanubian crust was thrust toward the northwest over the Saxothuringian foreland. Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The ENE – WSW striking line KTB 8502 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N. The profile runs close to the area of the KTB drill hole, thereby crossing the DEKORP 3D survey ISO 1989. As well as the lines KTB 8501 and 8503 the profile 8502 was arranged parallel to strike, running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). In the southwest KTB 8502 crosses the Franconian Line, a fault zone which separates the crystalline Bohemian Massif from a foreland. Farther to the northeast KTB 8502 crosses metamorphic nappes and Variscan granites of the Erbendorf-Vohenstrauss Zone.
The 56 km long KTB Line 3 was recorded in 1985 as part of deep seismic reflection investigations for the DEKORP (German Continental Seismic Reflection Program) and KTB (German Continental Deep Drilling Program) projects.

The WSW – ENE striking line KTB 8503 is located normally to the KTB lines 8504, 8505 and 8506 and to DEKORP 4N running ca. 16 km south of the KTB drill hole. As well as the lines KTB 8501 and 8502 the profile 8503 was arranged parallel to strike running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). In the southwest KTB 8503 crosses the Franconian Line, a fault zone which separates the crystalline Bohemian Massif from a foreland. Farther to the northeast KTB 8503 runs through metamorphic nappes and Variscan granites of the Erbendorf-Vohenstrauss-Zone.

Both units were welded to one another by a low-pressure metamorphism accompanied by polyphase deformation (DEKORP Research Group, 1987, 1988). The WSW – ENE striking line KTB 8501 is located ca. 12 km north of the KTB borehole. From southwest to northeast KTB 8501 crosses KTB 8504, DEKORP 4N, KTB 8505 and KTB 8506. As well as the lines KTB 8502 and 8503 the profile 8501 was arranged parallel to strike running across the NW-SE directed system of block-faults at the southwestern margin of the Bohemian Massif (DEKORP Research Group, 1988). The most important tectonic lineament, crossed by KTB 8501, is the NW-trending Franconian Line. The fault zone separates the crystalline Bohemian Massif from the foreland, which is covered by Mesozoic and Upper Palaeozoic sedimentary rocks (DEKORP Research Group, 1987).

The NNW-SSE trending line KTB 8504 runs ca. 15 km southwest from the KTB drill site, nearly parallel to KTB 8505, KTB 8506 and DEKORP 4N and perpendicular to KTB 8501 – 8503. The profile is located southwest of the Franconian Line inside the Permo-Carboniferous and younger sediments of the Mesozoic foreland, which is underlain by a westward continuation of the Erbendorf-Vohenstrauss Zone (DEKORP Research Group, 1988).

The SSE-NNW trending line KTB 8505 runs from the Upper Palatinate Forest in the southeast to the Fichtel Mountains in the northwest. The line is located ca. 9 km northeast from the KTB drill site, nearly parallel to KTB 8504, KTB 8506 and DEKORP 4N and perpendicular to KTB 8501 – 8503. The profile also crosses the DEKORP 3D survey ISO 1989. KTB 8505 was arranged to explore the Tirschenreuth-Mähring segment of the Saxothuringian/Moldanubian boundary region (DEKORP Research Group, 1988).
