The country of Malta consists of an archipelago of seven islands, three of which are inhabited (Malta, Gozo, and Comino).

The Maltese Islands are located on the northern flank of the Pantelleria Rift, between Tunisia and Sicily to the south of the Sicilian platform.

Geologically, the islands consist exclusively of sedimentary rocks, mostly limestone of Oligocene and Miocene age, although older rocks (Cretaceous and Eocene) have been encountered in deep boreholes.

The stratigraphic succession outcropping on the islands consists of five main litho-stratigraphic units of Oligocene-Miocene ages defined from the basement to the top by: the Aquitanian-Burdigalian Lower Coralline Limestone (140 m thick), the Chattian to Langhian Globigerina Limestone (20 - 200 m thick), the Langhian Blue Clay Formation (75 m thick), the Greensand Formation (few meters thick) and the Tortonian Upper Coralline Limestone (100 m thick). The Globigerina Limestone is composed of three members called Lower, Middle and Upper Globigerina Limestone.

Malta yields hardly any crystallized mineral specimens except for calcite and gypsum. It is much better known for its fossil specimens, although their export is technically illegal. Ubiquitous cerussite pellets in the soil are the product of alteration of bullets and birdshot and are not native.
