Please forgive my curiosity and interest. Does deep-sea and shallow-sea sedimentation always correspond exactly to the sequence stratigraphy we currently know? Let's take carbonate sequence stratigraphy as an example, reef formers are shaped by both hrm sea level change and relief as far as we know. So, if we encounter a contradictory sequence of this in the field, how should we interpret it? What we really want to ask is, could there be time intervals where the sequence does not depend on sea level or relief? thanks for your attention.
Dear Gokhan.,
My opinion is that sequence stratigraphy is a model and as such only represents one aspect (related to eustacy/accomodation space)., and therefore there are many examples in the record record that would not conform to this model. There are significant benefits in the sequence stratigraphic approach as long as aware of the potential pitfalls and busts. I recommend a holistic approach using the data to generate models, rather than a model to explain the data. I refer you to one of my publications on the Eagle Ford where para-sequences based on varying sea-level were described, but based on the data we infer climate oscillations and oceanographic changes that are cyclic (see Eldrett et al. EPSL, 2015). In this publication we present an alternative interpretation or model. I would suggest start with the data and integrate with other disciplines to try and reduce the errors/uncertainty. In interpretation there is rarely one answer.
Dear James S Eldrett ,
I will examine the work you suggested to me. I am already extremely excited to find someone who speaks the same language as me and to see that this person opens new windows for me. thanks a lot.
For sure. The balance between sedimentary supply, i.e. topography and climate, the rate of subsidence, local and global changes in sea level, local disturbances such as an asteroid impact, seismicity and any other have the power to leave a signature in the sedimentary record.
