Análise Fatorial (modo-Q) em estudos quantitativos de nanofósseis calcários do Quaternário Superior em um testemunho da Bacia de Campos, RJ - Brasil
Palavras-chave:Calcareous nannoplankton, Q-mode factor analysis, Quaternary
In this paper a Q-mode factor analysis was carried out to study the late Quaternary calcareous nannofossils from core PC-01 (Campos Basin – Brazil). Using CABFAC computer program, two factors were obtained and explain 95,90%, the Factor 1, explain 93,69% and is dominated by speci Florisphaera profunda, wich is restricted to lower euphotic zone, this imply in deep nutricline and thermocline. Factor 2 explain 2,21% and is dominated by species Rabdosphaera clavigera and Gephyrocapsa oceanica, both ralated to shallow nutricline and thermocline. As the core is located mainly in a glacial sequence, it was possible to verify the changes of thermocline and nutricline in this core.
