TABLE 5. — Sedimentation rates determined at every 100 meters throughout the Honda Group at La Venta site and sedimentation rates determined for each sedimentary succession interpreted as a main depositional feature of an accumulation system. Abbreviations: a, overbank deposits with incipient paleosols; b, channel sandstone; c, overbank deposits without paleosols; d, overbank deposits with paleosols; e, channel fill and debris flow; and f, swamp/lake deposits. | Stratigraphic | Sed. rate | Depositional | Stratigraphic | Sed. rate |
