STABLE-ISOTOPE STRATIGRAPHY OF BRACHIOPODS FROM PENNSYLVANIAN SHALES IN TEXAS Academic Article uri icon

abstract

  • Stable-isotope stratigraphies have been generated for brachiopods from five Late Pennsylvanian sections (upper Winchell cycle, Finis shale, Colony Creek shale, Necessity cycle, and Wayland shale) in north-central Texas to examine the relationship between isotopic composition, paleoenvironment, and sea-level change. Nonluminscent calcite from more than 300 specimens of 4 species of brachiopod (Composita subtilita, Crurithyris planoconvexa, Eridmatus texana, Neospirifer cameratus) was analyzed. Sedimentological and paleontological data are used as evidence for paleoenvironmental change. from Authors
