Figure 9 Field lithic clast analyses and sample location on stratigraphic logs along a down-slope
transect near San Miguel deTajao, proximal (Locality 62), medial (Locality 6) and distal (Locality
66) from the break in slope (see Figure 7 for legend of lithic clast abbreviations and numbers).
accompanied by a decrease in altered lithic clasts (27–14%, San Miguel de Tajao;
36–24%, Orotava Valley). In addition, the relative proportions of lithic clasts
observed in the caldera wall (Figure 12) resemble those in the Orotava Valley
(Figure 11) (cf. Bandas del Sur sites).
