A contribution to Holocene shore displacement and environmental development in Vantaa, South Finland: the stratigraphy of Lake Lammaslampi
The sediments of Lammaslampi, a small lake situated about 32 m a.s.l. in Vantaa, were studied by means of pollen and diatom analyses and loss-on-ignition measurements. In addition x-ray diffraction analysis was used to examine the mineral composition of the basal part of the profile, and five radioc...

| description | The sediments of Lammaslampi, a small lake situated about 32 m a.s.l. in Vantaa, were studied by means of pollen and diatom analyses and loss-on-ignition measurements. In addition x-ray diffraction analysis was used to examine the mineral composition of the basal part of the profile, and five radiocarbon determinations to date the local shoreline displacement. The basin was continuously connected to the Baltic until it became isolated as the result of the isostatic uplift after the Litorina transgression 6 550 ± 170 C14 years BP. The »early Mastogloia phase» in the region was dated to c. 7 700 BP and the beginning of the Litorina stage to c. 7 300 BP. |
