The
PPDM Biostratigraphy Initiative - a Final Model Review
by Robert B. Witrock at the
Public Petroleum Data Model Association 2003 Spring Conference, Houston, TX,
June 2, 2003
Robert Witrock provides an update on the status of the Biostratigraphy Work
Group. Biostratigraphic data underpin the conceptual ordering of rock sequences.
Its analysis helps determine the age and reconstruct the depositional history on
a local, regional and global level. Key paleontologic information is obtained
from a variety of sampling methods, either from outcrops or from the subsurface.
After initial fossil identification, various stratigraphic zonations and
paleoenvironments can be recognized. Syndepositional and post-depositional
events such as unconformities, condensed sections, sequence boundaries and
thermal alteration may be recorded and can be included within a paleontologic
report. From the detailed sample descriptions, a paleontologic summary can
ultimately be derived, containing biostratigraphic and paleoecologic
information, displayed in text and graphic form. The PPDM biostratigraphic model
provides a standardized repository for storing and retrieving the paleontologic
data at various levels of resolution.
