Abstract This paper presents a Geographic Information System catalogue of the submarine landslides of the Spanish continental margin and describes the problems associated with harmonizing the catalogue with its onshore homologue. The data model structure is described to explain how to apply the rules and specifications following the Infrastructure for Spatial Information in Europe (INSPIRE). Because of the singularities of the marine environment compared with those of land, integrating the submarine landslide catalogues into INSPIRE specifications requires the following procedures: (1) simplification of the list of values of state of activity into three categories: active, dormant and relict; and (2) inclusion of debris avalanches and turbidites as new typologies of landslides. This paper discusses the problems associated with harmonizing different data types and units from different sources, such as the thickness (metres and seismic two travel time) or the age of the event, and a numeric code for the geological timescale is proposed to harmonize these data. We establish whether an item is required based on the reliability of the landslide event, which is categorized by three levels (high–middle–low) depending on the precision of the data source, methodology used and quality of the publication where the data are obtained.

Pumpellyite associated with actinolite, epidote, prehnite, chlorite, albite, white mica, titanite, smectite, and calcite is found in tholeiitic dolerites of Late Triassic (Liassic?) age, where it fills veinlets, replaces primary plagioclase and orthopyroxene, and appears in the groundmass. The dolerites, metamorphosed during the Eo-Alpine event, crop out as tectonic blocks several hundred meters in size, covering an approximate area of 0.1 km 2 next to the town of Archidona, Málaga province, southern Spain. A 4.0-mm-thick vein filled with compact bundles of needlelike pumpellyite was selected for analysis. Very minor amounts of calcite and smectite appear as a thin wall coating in this vein. Separates of pure pumpellyite were analyzed by X-ray diffraction, transmission electron microscopy–analytical electron microscopy, inductively coupled plasma, and electron probe microanalysis (XRD, TEM-AEM, ICP, and EPMA). The chemical analyses show a close agreement between the ICP analysis and the mean value of 60 probe measurements. The average of six semiquantitative AEM analyses plot close to the points above. The X Fe 3+ values (= 100Fe 3+ /Fe 3+ + Al tot ) are 20.7% for the EPMA mean (all Fe as Fe 3+ ) and 18% for the ICP analysis (with Fe 3+ and Fe 2+ analyzed separately). Cation distribution in the Z, Y, X, and W positions agree closely with the ideal stoichiometry (6, 4, 2, and 4, respectively), whereas the cation totals are 15.91 for the EPMA mean and 15.99 for the ICP analysis. The Archidona pumpellyite is strongly impoverished in rare earth elements (REE) as a whole and shows a smooth U-shaped REE pattern. A maximum enrichment of about four to five times chondrites is shown by the heaviest rare earth elements Yb and Lu, respectively. The unit-cell parameters of the pumpellyite were determined as follows: a = 8.814 ± 0.002, b = 5.925 ± 0.001, c = 19.125 ± 0.003 A, V = 990.307 ± 0.228 A 3 , and β = 97° ± 0.8′. Pumpellyite needles in the vein were also examined by selected-area electron diffraction (SAED) and TEM imaging. From [010] zone axis electron diffraction patterns with no streaks along c * and images showing only some twin faults parallel to (001), it was concluded that pumpellyite was not significantly intergrown with epidote, lawsonite or sursassite. This absence of microdefects indicates a remarkable structural homogeneity of this pumpellyite sample.
