Fig. 1. Location of the studied area in Romania (left) and the geological structures and location of the fossiliferous localities (right) in Gorj County (modified after Codarcea et al., 1968): 1 — Igneous rocks; 2 — Sarmatian s. l.; 3 — Maeotian; 4 — Upper Besarabian–Maeotian; 5 — Holocene; 6 — Pleistocene; 7 — Volhynian–Lower richnessBessarabian(Bercia; 8 —et al., fossiliferous 1968). Theselocality. deposits are situated in the Novaci depression and continue to the east and to the west, as well as south of the Ciocadia–Săcel anticline (Bercia et al., 1968). The paleontological content is also represented by invertebrate species such as: Unio cf. subrecurvus Teisseyre 1907, Radix cf. velutina Deshayes 1838, and Congeria navicula Andrusov 1897 (Popescu, 1955; Bercia et al., 1968). The last sedimentary sequence, situated east of the Cerna River, on the northern rim of the Dacian Basin is composed of detritic deposits containing rare Mactra Linnaeus 1767 remains, characteristic of the Bessarabian and Khersonian, while eastwards, towards Râmnicu Vâlcea these detritic deposits overlay the Lower Bessarabian formations with C. pesanseris, and above these, the Maeotian deposits, predominantly detritic, composed of sands and sandy marls with gravel interlays follow (Bercia et al., 1968).

Digitized geological and geophysical data from the Po Plain and the northern Adriatic Sea (north Italy) collected from public sources.
<p>The database is a supplementary material of:</p><p>Livani, M., Petracchini, L., Benetatos, C., Marzano, F., Billi, A., Carminati, E., Doglioni, C., Petricca, P., Maffucci, R., Codegone, G., Rocca, V., Antoncecchi, I. (2023). Subsurface geological and geophysical data from the Po Plain and the northern Adriatic Sea (north Italy). Earth System Science Data Discussions, 15, n. 9, 4261-4293, doi: 10.5194/essd-15-4261-2023</p><p> </p><p>This database comprises subsurface geological and geophysical data from the Po Plain and the northern Adriatic Sea (north Italy). We realized the database by collecting, revising, and digitizing data, originally in raster format, from public sources. These data have been then used to reconstruct the overall subsurface 3D architecture and to extract the physical properties of the subsurface geological units.</p><p>The data have a common geographical system: WGS 84/UTM zone 32N; EPSG: 32632.</p><p>The database contains borehole information from 160 deep wells (i.e., wellhead coordinates, rotary table elevation, measured depth, true depth, total depth and deviation survey) and digitized Spontaneous Potential, Gamma Ray, and Sonic logs. Five horizons were digitized from 61 geological cross-sections and from 10 isobath maps that roughly correspond to the boundaries of units showing different lithological properties and with different mechanical properties. The horizons are, from the oldest to the youngest: the top of the magnetic basement, the top of the carbonate succession, the base of the Pliocene, the base of the Calabrian and the base of recent continental deposits. In addition, the gridded surfaces of the 3D geological model are available.</p><p>We organized the database into two groups: "primitive data" and "derived data".</p><p>Primitive data are the result of the digitization of public data. The database of the primitive data is formed by the main horizons reported in the geological cross-sections, the isobaths of the main geological surfaces, the well locations, comprised their trajectory along depth, lithological and stratigraphical information, and geophysical logs from composite well logs. Well data include specific sets of well logs aimed to geological/mechanical characterization of the geological units (e.g., Spontaneous Potential log, Resistivity log, Gamma Ray log, and Sonic log).</p><p>Derived data consist of two datasets: i) the primitive isobaths maps and geological cross-sections data that have been filtered and verified after a data accuracy analysis performed to unravel discrepancies in the interpretation of the subsurface geological horizons; ii) a set of regional surfaces of the main geological units of the Po Plain subsurface. These surfaces were generated by interpolating the filtered primitive data and without considering the fault occurrence/displacements.</p><p>Primitive and derived data are provided in delimited text file format organized according to the data type (i.e., well, geological cross-section, map and gridded surface). The format and the organization of data are explained in the related "readme" file presents within each data folder.</p><p>Our database represents a collection of the main published works regarding the Po Plain. Detailed studies related to specific sectors of the Po Plain might not be present in our database.</p><p>Further details about the data processing and organization are given in the related manuscript.</p><p> </p>
