Data identifying observation locations (shown as points) describing the bedding orientation of bedrock units. The scale of the data is 1:10 000 scale. Coverage is provided for the main Maltese Islands. Bedrock measurements describe the orientation of bedding in terms of dip and dip-azimuth. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles.

Faults are depicted as linear features (shown as polylines) representing a structural contact between geological units; Faults are typically associated with the bedrock theme and identify a plane of movement or failure where a body of bedrock has been fractured and displaced relative to another, by a large-scale process affecting the earth's crust. The data are available in vector format (containing the geometry of each feature linked to a database record describing their attributes) as ESRI shapefiles.

The Folds theme provides information on the structural bedrock geology of the Maltese islands. It was produced from the geological resurvey of the Maltese Islands undertaken in 2021 and 2022. This map depict localised structural folding of bedrock. The map features represent the fold axis of the feature.

Data identifying boundaries (shown as polylines) describing the contact between geological units at the margins of karstic dolines and sinkholes. The scale of the data is 1:10 000 scale. Coverage is provided for the main Maltese Islands. The data includes attribution to identify the local names, and postulated age of formation of the features (in varying levels of detail). Several modes of failure are represented by the doline/sinkholes, The boundaries therefore represent planes of structural failure or fl...

Data identifying landscape areas (shown as polygons) attributed with geological names and deposit descriptions. The scale of the data is 1:10 000 scale. Superficial deposits are the youngest geological deposits formed during the most recent period of geological time, the Quaternary, which extends back approximately 2.588million years from the present. They lie on top of older deposits or rocks referred to as bedrock. Superficial deposits were laid down by various natural processes such as action by water, ...

This dataset consists of a geological map of the Maltese Islands mapped at 1:10,000 scale. It consists of seven map layers: bedrock, superficial, artificial, faults, folds, solution subsidence features and bedding measurements.

This dataset consists of a geological map of the Maltese Islands mapped at 1:25,000 scale. It consists of the following layers: quaternary, tertiary, stratigraphical boundaries, bedding, faults and solution subsidence structures.

This map shows the sediments close to the surface (or sea bottom), down to a depth of about 5 meters. This map is based on existing maps of the former Rijks Geologische Dienst and, where necessary, supplemented by unpublished data. The sediments are classified according to the new lithostratigraphical legend used by TNO since 1997. This classification is based on lithological and seismological properties, and on stratigraphic position and origin. The age of the sediments is not taken into account in this c...

The Geological map of the Republic of Srpska (1:300 000) is the first clear map of Srpska that shows geological structure and the history of the terrain creation from the Paleozoic to the Quaternary, covering the period of more than 600 million years. Knowledge of geological structures is particularly important for every state, because it conditions the richness or poverty in terms of mineral resources. A type and kind of rocks are prerequisites for the creation of drinking water reserves, and bedrocks, to...

Geological map of the South Portuguese Zone, at a scale of 1:400,000, in which the geological legend on both sides of the border has been harmonized, with unified criteria between Spain and Portugal. This cartography is a product resulting from the GEO_FPI project: GEO_FPI: cross-border observatory for the geo-economic evaluation of the Iberian Pyrite Belt, financed by the European Regional Development Fund (ERDF) within the program INTERREG V-A Spain– Portugal (POCTEP) 2014-2020. The main beneficiary of t...
