中文摘要
这项提议要求支持一项研究,利用不同的湖泊沉积物获得美国中西部整个全新世干旱和/或土壤侵蚀的高分辨率(十年制)记录。倡导者打算开发一套磁性参数,以根据矿物学、浓度和粒度分布来快速描述沉积物样品的磁性部分,并确定指示风成和侵蚀输入的关键参数。为了评估我们方法的准确性、可靠性和稳健性,他们将把选定层位的磁学结果与更耗时的风尘和侵蚀的沉积学和地球化学指标进行比较。
英文摘要
This proposal requests support for a study to obtain a high resolution (decadal scale) record of drought and/or soil erosion in the mid-western United States throughout the Holocene using varved lake sediments. The proponents intend to develop a set of magnetic parameters to rapidly characterize the magnetic fraction of a sediment sample in terms of mineralogy, concentration and particle-size distribution and to identify the key parameters that are indicative of eolian and erosional input. To assess accuracy, reliability and robustness of our method they will compare their magnetic results for selected horizons with more time-consuming sedimentological and geochemical proxies of eolian dust and erosion.
