PHYTOLITH ANALYSIS OF A GROUNDSTONE FROM LITTLE ANTELOPE VALLEY, LONG VALLEY CALDERA, MONO COUNTY, CALIFORNIA

A single piece of groundstone, recovered in Little Antelope Valley in the Long Valley caldera
in Mono County, California was examined for phytoliths to obtain information about plants that
might have been ground using this tool. Phytolith analysis was selected as perhaps the most likely
to yield results because the groundstone had been washed approximately 15 years ago.
Therefore, pollen analysis was not deemed to be possible.

本次研究对采集自加利福尼亚州莫诺县长谷火山口小羚羊谷的一件磨制石器（groundstone）开展了植硅体（phytoliths）分析，以获取该工具曾用于研磨的植物相关信息。鉴于该磨制石器已于约15年前被水洗，研究人员选择植硅体分析作为最有可能获得有效结果的检测手段，因此花粉分析（pollen analysis）被认定无法开展。
