\description{
Aumento consideravel de argila em pequena distancia vertical
(\\<= 7.5 cm) na transicao A/E -> B:
\itemize{
  \item argila A < 200 g/kg: argila B \\>= 2x A; OR
  \item argila A 200-400 g/kg: incremento absoluto \\>= 200 g/kg
        (i.e. de 300 -> 500); OR
  \item argila A \\>= 400 g/kg: incremento absoluto \\>= 220 g/kg
        (i.e. de 420 -> 640).
