The effects of chemical composition and distribution on the preservation of phytolith morphology

Applied Physics A, 2013
Different types of phytolith even when coming from the same plant react to high temperatures in different ways. To understand the behavior of phytoliths upon heating, we examined composition and distribution of some elements within different phytolith types using SEM-EDS and synchrotron radiation μ-X-ray fluorescence.

The transformation of phytolith morphology as the result of their exposure to high temperature

Microscopy Research and Technique, 2012
AbstractPhytoliths are an important component for interpreting the ancient botanical record. However, phytoliths can be altered through heating, either as the result of such activities as firing ceramics, clay molds use for casting metal or in hearths.

Phytolith morphology research on wild and domesticated rice species in East Asia

Quaternary International, 2013
Abstract Systematical descriptions of phytoliths from rice species in East Asia are scarce. In order to investigate the relationship among diversity of phytolith morphology, taxonomy and genome, comparative research on phytolith morphology of the wild and domesticated rice species is first performed on the basis of statistics and cluster analysis ...

Assessing Bioturbation in Archaeological Sediments using Soil Morphology and Phytolith Analysis

Journal of Archaeological Science, 1999
Abstract Analysis of ditch infill at an early modern burial complex (dating from the 16th century ad) in upland northwestern Thailand was undertaken to assess the role of bioturbation in interpreting palaeolandscapes. Evidence for bioturbation and water percolation is contrasted with AMS radiocarbon determinations and a phytolith sequence. While more
