According to the relationship between the type of turbidite and the combination of trace fossils, 15 kinds of ichnogenus are divided into two types, transition type Zoophycos ichnofacies and deep-water type Nereites ichnofacies. The former is mainly distributed in the transitional area between proximal to distal area of turbidite and the latter in the distal area.展开更多

文摘This paper mainly discusses 15 kinds of ichnogenus found for the first time in the study area from the water depth distribution, body size of trace fossils and the relationship between sedimentary environment and deep-water ichnofacies, based on the summarizing of the sedimentary character of deep-water slope environment in the study area. According to the relationship between the type of turbidite and the combination of trace fossils, 15 kinds of ichnogenus are divided into two types, transition type Zoophycos ichnofacies and deep-water type Nereites ichnofacies. The former is mainly distributed in the transitional area between proximal to distal area of turbidite and the latter in the distal area.
