Geochemistry and Molecular Microbiology of Travertine

0000501Bonheyo黄石国家公园猛犸象温泉将评估微生物代谢、水和碳酸盐化学以及石灰华流体包裹体中潜在DNA保存之间的因果关系。将对单个现代泉水(40摄氏度至75摄氏度之间的三个1平方米的站)和相应的古代沉积物(100、1000、8000、25000和45000年前)进行分析。这种水-固-微生物过程模型的建立将定量跟踪微生物DNA的埋藏和石化过程。

0000501BonheyoThe causal relationships between microbial metabolism, water and carbonate chemistry, and potential DNA preservation in travertine fluid inclusions will be evaluated at Mammoth Hot Springs, Yellowstone National Park. Analyses will be done on a single modern spring (three 1 m2 stations from 40? - 75?C) and corresponding ancient deposits (100, 1000, 8,000, 25,000, and 45,000 years old). Creation of this aqueous-solid-microbial process model in the modern will quantitatively track the entombment and fossilization of microbial DNA.
