Transcripción del resumen del autor. A binary sequence of deposits was elaborate starting from the observations of ground. It applies to various scales and various of deposits media. The binary sequence is made up of two sequences. Each sequence is subdivided in two cycles. The lower cycles account for the three fifths in duration and the higher cycles the remaining two fifths. On the whole, that made four cycles. In detail, this binary sequence includes ten terms of facies delimited by ten discontinuities of which four among they are significant. These last delimit the four cycles. One distinguishes two m.f.s. or maximum flooding surface in the center from the two higher cycles.
