Origin of the upper Capitan-Massive limestone (Permian), Guadalupe Mountains, New Mexico-Texas: is it a reef?

Article Abstract:

A study was conducted to determine the origin of the upper Capitan-Massive limestone in Guadalupe Mountains, NM, to determine whether it is a reef formation. Data showed that sponges present in the area have mixed histories, an undirectional blast basinward has toppled and broken skeletons as suggested by its arrangement and alignment, and a uniform presence of unidentified tubules and Shamovella obscura. Results established that the upper Capitan-Massive is a biological reef with a skeletal framework that grew by upward growth.

Relations between relative changes in sea level and climate shifts: Pennsylvanian-Permian mixed carbonate-siliciclastic strata, western United Staes: discussion and reply

Article Abstract:

A study on the relationship between climate change and glacioeustatic sea-level fluctuation in the late Paleozoic sedimentary cycles of the western US is evaluated. Three main problems are observed regarding the study's analysis. These are a lack of high time-stratigraphic resolution allowing comparisons of noncontemporary sedimentary cycles, the comparison of cycles with varying temporal scale and limited climatic data available from single sedimentary cycles.

Paleoweathering of Mississippian Monteagle Limestone preceding development of a lower Chesterian transgressive systems tract and sequence boundary, middle Tennessee and northern Alabama

Article Abstract:

The pedologic, sedimentologic and stratisgraphic conclusions of a study on the Mississippian Monteagle Limestone in Tennessee and Alabama is inconsistent with previous data on the Hartselle Sandstone. Interpretations of the tectonic origins of the orogenic belts in the Appalachian and Ouachita regions were based on arguments concerning the southward progradation of the Hartselle Sandstone.
