POLLEN ANALYSIS AND AMS RADIOCARBON DATING OF SEDIMENT FROM GEO TRENCHES IN RESACA PALO ALTO, BROWNSVILLE, TEXAS

Author(s): Linda Scott Cummings; Kathryn Puseman

Year: 2011

Summary

A series of geo trenches were excavated across the Resaca Palo Alto, into the levees, and just outside the Resaca near Brownsville, Texas. Resaca Palo Alto is a paleochannel of the Rio Grande River. The Resaca deposits consist of three sediment packages deposited during different episodes of fluvial activity. Pollen analysis was conducted on samples from the geo trenches to provide information concerning the paleoenvironmental history of the Resaca. In addition, charcoal recovered from the lower channel sand was submitted for AMS radiocarbon dating.
