Le concrezioni della grotta Mannute Piccola (prov. di Lecce)

The present paper describes some "speleothems" observed at the cave "Mannute Piccola", one of the coastal caves of the Mannute system. A biologic origin is hypothesized for some of the speleothems. In addition, geologic and morphologic data allow to present preliminary consideration on paleogeography and neotectonics of this sector of Apulia. In particular, the age of formation of the cave which host the speleothems appears to be younger than the Lower Cattian, while the genesis of the speleothems maybe referred to the Middle or Late Pleistocene. At least one phase of subsidence probably occurred between these two events.
