Incised valleys were not widely recognized prior to the 1980s. Most early workers forced the isolated, incised-valley deposits along an uncomformity into a single continuous unit, ignored them by including them within larger stratigraphic units, or interpreted them as deltaic distributaries or non-incised fluvial channels.

Incised valleys were not widely recognized prior to the 1980s. Most early workers forced the isolated, incised-valley deposits along an uncomformity into a single continuous unit, ignored them by including them within larger stratigraphic units, or interpreted them as deltaic distributaries or non-incised fluvial channels. In the last decade, intense interest in the influence that changes in accommodation space have on stratigraphic organization has focused attention on incised-valley systems, because they are one of the most visible records of major decreases in accommodation. In practical terms, they are also a significant key to the identification of sequence-bounding uncomformities. As a result, many successions have been re-examined and incised-valley fills are being found in rapidly growing numbers. This volume is an outgrowth of this widespread interest in incised-valley sedimentation. Many of the papers were initially presented at the Special Session on "Recognition and Facies of Incised Valley Fills" held at the AAPG-SEPM Annual Meeting (Calgary) in June, 1992.
