Re: Sequence Strat Standardization: IWGSS vs ISSC
Wow! Has dr. Embry entered the discussion.
Thanks for pointing us to your book. I remember reading parts of this a while back, but have not been that involved the last months. I'm printing it now and will give it a thorough read.
I have one question though after reading the intro, since you're now here...
Near the end of the introduction you state that:
Data from other stratigraphic disciplines such as biostratigraphy and chemostratigraphy can also contribute to surface recognition (e.g., help determine stratal geometries) but cannot be used for surface characterization.
I might be misinterpreting this and it may be tackled in later chapters, but can’t biostratigraphic interpretation indicate depositional environment and thus be a way to characterize a surface? Also periods of nondeposition can be observable through plant roots, certain pollen, oxidization of microfossils etc. And can’t chemical interpretation also indicate depositional environments (the CCD for instance) and periods of nondeposition like leaching of paleosols?
You might be refering to 'pure' biostratigraphy, which solely aims to date/correlate strata based on a particular fossil assemblage. However, most biostrat reports we recieve also include interpretation of the depositional environment. We include these interpretations in our GDE's, which ultimately help to characterize our sequences and feed into our sequence strat models.
Am I on the right track of what you're stating there?
Thanks again for joining and I hope we will be able to feed off of some of your wisdom.
