Stratigraphic Pollen Analysis (Other Keyword)
1-4 (4 Records)
Deposits within the Eagle Point Site (5RB4662), a rockshelter located along Piceance Creek in northwest Colorado, were sampled stratigraphically at close intervals for the purpose of building a detailed paleoenvironmental pollen record for this portion of Colorado. Although the sampling model called for sampling at approximately 2 cm intervals, the intervals collected varied because some levels were obviously unconsolidated and represented a single depositional, non-cultural event. In this...
POLLEN ANALYSIS OF A GEOPROBE CORE FROM A KARST SINKHOLE AT FT. CAMPBELL, KENTUCKY (2004)
Forty-eight pollen samples were examined from a stratigraphic core collected from the fill of a broad sink hole that appeared to be somewhat mature on the Ft. Campbell property in southwest Kentucky. This core was collected because fill in the sink hole was believed to represent the entire Holocene. The base of the core appears to be bedrock. Pollen samples were examined at varying intervals, depending on stratigraphy in the core, to provide a stratigraphic record of vegetation throughout...
STRATIGRAPHIC POLLEN ANALYSIS AT 5LA5838, A CIRCULAR STRUCTURE IN PICKETWIRE CANYON, SOUTHEASTERN COLORADO (2003)
Site 5LA5838 is a circular feature situated on a terrace above the Rio de las Animas Perdidas en Purgatario (Purgatory River). Onsite vegetation includes grasses, cholla and prickly pear cactus and sparse junipers. Riparian vegetation nearby includes willow and cottonwood. Seven stratigraphic pollen samples were analyzed for potential economic uses of plants at the site and to discern changes in the plant community in the area. One radiocarbon date at the site, 950±40 RCYBP, was reported...
STRATIGRAPHIC POLLEN ANALYSIS OF ELEVEN CORES NEAR EDGEWOOD, MARYLAND (2003)
Several cores were extracted from sediments of the peninsula between the Bush and Gunpowder Rivers near Edgewood Maryland. Samples were extracted at irregular intervals from eleven of these cores and submitted for environmental pollen analysis in order to assist in determining ages for strata underlying the peninsula. Accurate determination of biostratigraphic ages are difficult, at best, and require extensive, close-interval sampling to determine changes in frequency and the appearance and...
