摘要
Abstract
The devlopment history of ichnology and its current advances are briefly reviewed in this paper,and the mea-surement of ichnofabric indices is introduced. It is agreed that the ichnological suites and their variation could reflectchanges in substrate consistency, physical environmental energy, sedimentation rate, bottom current, oxygen con-tent, water chemistry and water depth, all these are consistent with both phases and magnitudes Of the associatedsea - level cycles. Based on the analysis above, it has been pointed out that the ichnofossils are sensitive to paleoenvi-ronmental changes as a result of sea level dynamics, the potential of ichnology for the sequence stratigaphy could beindicated by at least the following five aspects: 1. determination and analysis of cyclic sequences; 2. recognition and
interpreation of sequence stratigaphic boundaries; 3. analysis of condensed section; 4. facies succession analysis; 5.definition of marine or lacustrine shore zones.
