Located in the Southern Tyrrhenian Sea, they are part of the eastern sector of the Aeolian Arc together with Palinuro and Alcione seamounts, Panarea and Stromboli islands. The Lamentini group is situated on the continental slope and characterized by two summits, which reach -1,330 m and -862 m in depth. The Seamounts are named Lametino 1 and Lametino 2. Lametino 1 being the northern mount.
Samples dragged from a Mn deposit on the top of Lamentini Seamounts are mainly formed by todorokite in combination with very scarce birnessite. Todorokite and birnessite are the main minerals present in nodules and ferromanganesiferous concretions.
NOTES:
- The co-ordinates provided are central to the two peaks.
- In Rossi et al. (1980) the two seamounts are spelled as Lamentini.
- The Atlas of the Mediterranean Seamounts and Seamount-like structures (2015) also provides the spelling Lametino 1 and Lamentino 2, as does Dekov et al. (2007).
