Ostracod valves were found in the lowermost ca. 3 m of the sequence at Site 1, dated to ca. 28-24 kyr B. P., and throughout the sequence from Site 6 which represents the interval 23-17 kyr B. P.
Four cores (ranging between ca. 9 and ca. 14 m in length) from Lago di Albano in Central Italy were studied for their ostracod content, as well as algal and bacterial pigments, CaCO3 and concentration of organic matter. Cores PALB 94 1E and PALB 94 1C from Site 1, located at the bottom of a steep slope at 70 m water depth, where oxygen concentration is below 6 mg l(-1), spans the Holocene and the late Pleistocene until 28 kyr B. P. (calibrated age). The other cores, PALB 94 6A and PALB 94 6B taken at a depth of 30 m, where oxygen is 7-11 mg l(-1), represent mainly Pleistocene deposits.

Abstract
Four cores (ranging between ca. 9 and ca. 14 m in length) from Lago di Albano in Central Italy were studied for their ostracod content, as well as algal and bacterial pigments, CaCO3 and concentration of organic matter. Cores PALB 94 1E and PALB 94 1C from Site 1, located at the bottom of a steep slope at 70 m water depth, where oxygen concentration is below 6 mg l(-1), spans the Holocene and the late Pleistocene until 28 kyr B. P. (calibrated age). The other cores, PALB 94 6A and PALB 94 6B taken at a depth of 30 m, where oxygen is 7-11 mg l(-1), represent mainly Pleistocene deposits.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
