Sequence stratigraphy of Lower Triassic Feixianguan Formation in Fuling area
Online published: 2011-06-20
According to the fundamental principle of sequence stratigraphy, based on the analysis of rock type, sedimentary cycles identified fromlog curves and superposition styles, Lower Triassic Feixianguan Formation in Fuling area is divided into two third-order sequences, eleven fourth-order sequences and twenty fifth-order sequences.Furthermore, the third-order sequence and high-frequency sequence stratigraphic framework are established through the control action of key interface and the control action of low-frequency sequence on high-frequency sequence.
