76 spot and shallow core samples from 13 acid to neutral acid were chosen for palynology, a first in the study of natural acid saline systems,
and used for a preliminary interpretation of paleovegetational and paleolimnological conditions. Samples were collected in June 2005 and January 2006.
Algae type A
Algae type B
Transmitted light and scanning electron microscopy were used to identify palynomorphs and palynodebris. Palynomorphs (pollen, spores and non-marine algae)
were abundant, diverse and well-preserved.
The most common pollen belong to the following families: Asteraceae, Chenopodiaceae, Myrtaceae and Poaceae
