Geological Map of the Maltese Islands – Superficial

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, wind, and weathering. These superficial deposits are unconsolidated sediments such as gravel, sand, silt and clay. The digital data includes attribution to identify each deposit type.
