The geochemical series, obtained by X-ray fluorescence (XRF), showed tendencies towards significant levels of elements Al, Si, S, Ca, Br and Zr. Levels of Al, Si, and Zr, declined progressively towards the top of the core. Contrastingly, S, Ca and Br exhibited a gradual increase towards the top. This less evident trend also occurred for Sr.

The following groups were defined: Trees, Shrubs, Herbs, Aquatic and Spores. The Trees Group is composed of 9 types of pollen; the Shrubs Group is constituted of 7 pollen types; the Herbs Group is made up of 18 types of pollen; the Aquatic Group is made up of Alternanthera aquatica and Juncaginaceae pollen types; and the Spores Group is composed of Polypodium, Pteridophyta and 3 unidentified spore types
