The Service géologique du Luxembourg (Geological Survey of Luxembourg) SGL, a division of the Administration des ponts et chaussées (Roads and bridges administration), collects information about past and current mineral resource occurrence and extraction sites in Luxembourg. This information is assembled in a spatial database (about 800 records). The majority of these are building and dimension stone quarries (sandstone, limestone) and iron ore mines. Accessorily, there are slate quarries and a few other metallic ore mines. In the context of MINTELL4EU, about 550 validated records on quarries, gravel pits and mines were extracted and harmonized according to the MINTELL4EU guidelines.

The dataset contains information from de database BDMIN regarding the exploitations (abandoned, intermittent or active) and occurrences of industrial rocks and minerals. These data have been generated by the IGME throughout numerous projects, from the early 1970s to the present. The information is structured in different sections: Identification, location, mining domain, mining-I (Technical parameters), mining-II (Socio-economic and commercial parameters), geology and complementary information. The storage format is SQLServer. It is publicly accessible, except for some of the data which are restricted. This information is harmonized according to the specifications of the MIN4EU database model as part of the Mintell4EU project.
