a Axis 2 of the Principal Component Analysis performed on the X-ray fluorescence (XRF) scanning record, b mean-grain size measurements, c pollen sum of specific taxa from montane vegetation (Ericaceae, Myrica, Podocarpus), d pollen sum of specific taxa from evergreen humid forest (Myrtaceae, Elaeocarpus, Macaranga-Mallotus, Acalypha, Weinmannia, Moraceae-Urticaceae, Celtis, Araliaceae, Trema, Ilex, Noronhia, and Pandanus), e Poaceae pollen grains, and f influx of charcoal particles (>160 µm). The vertical bars represent the five key periods of different paleoenvironmental conditions defined in the text.
