The Continental
Shelf Department acts as the Geological Survey of Malta. The main
functions of the Survey are to upkeep and revise at a more detailed scale the
geological map of the Maltese Islands which is under the custodianship of the
Continental Shelf Department, to participate in EuroGeoSurveys (EGS) directors,
national delegate meetings and expert group meetings on various geological
themes and to participate in EGS and European Union geology related projects.
During 2016, the
Continental Shelf Department produced, using Geographic Information Systems
(GIS) technology, a digital version of the geological map of the Maltese Islands that was published in
1993. The 1993 map was resurveyed at a scale of 1:10,000 by the British Geological
Survey in 2021-2022 through a contract awarded by the Continental Shelf Department.
The entire geological information is now organised under 7 themes/layers: bedrock geology, superficial geology, artificial geology, fault features, fold features, solution subsidence features and bedding measurements. They are
available on a web-GIS platform. Please click on the map below to access the Web GIS Map Server for the 1:10,000 scale geological map of the Maltese Islands.
A description of the bedrock geology is given below.
