This paper continues the preliminary work presented at the I Congreso Latinoamericano de Paleontología in April, 1978. In this first part of a much broader study of the Tertiary of Arauco-Concepción, the work has been circumscribed to the analysis of five exploited coal beds of the Lota Member, Curarulahue Formation. Statistical data based on a greater number of samples than the previous paper are presented. This has allowed the characterization of the beds and the study of the mathematical correlation between them based on the palynological contents. New palynomorphs and their descriptions are included.
