<p>QDGC tables delivered in geopackage file<br> - - - - - - - - - - - - - - - - - - - - - -<br> QDGC represents a way of making (almost) equal area squares covering a specific area to represent specific qualities of the area covered. The squares themselves are based on the degree squares covering earth. Around the equator we have 360 longitudinal lines , and from the north to the south pole we have 180 latitudinal lines. Together this gives us 64800 segments or tiles covering earth.<br> <br> <br> Within each geopackage file you will find a number of tables with these names:<br> <br> <br> -tbl_qdgc_01<br> -tbl_qdgc_02<br> -tbl_qdgc_03<br> -tbl_qdgc_04<br> -tbl_qdgc_05<br> -etc<br> <br> <br> The attributes for each table are:<br> <br> <br> qdgc Unique Quarter Degree Grid Cell reference string<br> area_reference Country<br> level_qdgc QDGC level<br> cellsize degrees decimal degree for the longitudal and latitudal length of the cell<br> lon_center Longitude center of the cell<br> lat_center Latitudal center of the cell<br> area_km2 Calculated area for the cell<br> geom Geometry<br> <br> <br> Metadata<br> --------<br> Geodata GCS_WGS_1984<br> Datum: D_WGS_1984<br> Prime Meridian: 0<br> <br> <br> Areas are calculated with different versions of Albers Equal Area Conic using the PostGIS function st_area.

Rock-magnetic, paleomagnetic and multimethod paleointensity data from an upper Miocene lava flow sequence from São Vicente (Cape Verde)
<p>The folder “Praia Grande Paleomagnetism Data.zip” contains paleomagnetic thermal and alternating field demagnetisation data obtained on upper Miocene volcanic rocks from São Vicente (Cape Verde). Measurements were performed in the paleomagnetic laboratory of the University of Burgos (Spain). Data are in .txt format with the extension .rs3. Columns are separated by empty spaces. Data can be visualised and analysed with the Remasoft software (Chadima and Hrouda, 2006).</p> <p>The folder “Praia Grande rock magnetism Data.zip” contains data in .txt format of IRM acquisition curves (extension .irm), hysteresis curves (extension .hys), backfield curves (extension .coe) and thermomagnetic magnetisation versus temperature curves (extension .rmp) obtained on upper Miocene volcanic rocks from São Vicente (Cape Verde). Measurements were performed in the paleomagnetic laboratory of the University of Burgos (Spain). Columns are separated by tabs. Data can be visualised and analysed with the RockMagAnalyzer 1.0 software (Leonhardt, 2006).</p> <p>The folder “Praia Grande Thellier-Coe Data.zip”contains paleointensity determination data obtained with the Thellier-Coe method on upper Miocene volcanic rocks from São Vicente (Cape Verde). Measurements were performed in the paleomagnetic laboratory of the University of Burgos (Spain). Data are in .txt format with the extension .tdt separated by tabs. Data can be visualised and analysed with the ThellierTool software (Leonhardt et al.,2004).</p> <p>The folder “Praia Grande Multispecimen.zip” contains paleointensity determination data on upper Miocene volcanic rocks from São Vicente (Cape Verde) obtained with the multispecimen method (Biggin and Poidras, 2006; Dekkers and Böhnel, 2006; Fabian and Leonhardt, 2010) at Laboratorio Interinstitucional de Magnetismo Natural, Instituto de Geofísica, Unidad Michoacán, UNAM, Mexico. Two kinds of files can be found: Five .txt files (M0.txt, M1.txt, M2.txt, M3.txt, M4.txt) and five .jr6 files (M0.jr6, M1.jr6, M2.jr6, M3.jr6, M4.jr6). Both types of files are in .txt format. The .txt files directly provide the measurement data generated during the multispecimen experiments. The first columns of the .jr6 files display the following information: column 1: specimen name; column 2: experimental step (explanation below); columns 3, 4 and 5: three magnetisation components M(x), M(y) and M(z); column 6: exponent of the magnetisation components to obtain the magnetisation value in A/m. In the multispecimen experiments, the specimen-name (e.g. PRG1-3) can be divided in two parts, the first three characters indicate the sample (flow), the last character the specimen number (1 to 7). Eight different experimental steps (column 2) can be distinguished: NRM, A10, A20, A30, A40, A50, A60 and A70. They correspond to the measurement of the NRM and of steps in which fields of 10, 20, 30, 40, 50, 60 and 70 mT where respectively applied. Files M0 (.txt and .jr6) include only NRM measurements, files M1 include measurements of specimens heated with an applied field parallel to their NRM, files M2 include measurements of specimens heated with an applied field antiparallel to their NRM, files M3 include measurements of specimens heated in zero field and cooled down in an applied field parallel to their NRM, and files M4 include again include measurements of specimens heated with an applied field parallel to their NRM.</p> <p><strong>REFERENCES</strong></p> <p>Biggin, A., Poidras, T., 2006.
