Applying Argon Dating of Fine-Grained Silicates as a Geochemical Tool for Marine Sediments

PI将开发一种快速和廉价的辐射测量(K/Ar)方法来确定海洋粘土矿物的年龄，用于一系列地质和海洋应用中的来源追踪研究。该方法将应用于北太平洋和孟加拉湾的一套样品，分别研究粉尘和河流沉积物的来源。这项研究的一个结果可能是开发出一种常规的低成本的用于ODP体样品的Ar测年方法。

The PI will develop a rapid and inexpensive radiometric (K/Ar) method for determining the age of marine clay minerals for provenance tracer studies in a range of geological and oceanographic applications. The method will be applied to a suite of samples from the North Pacific and the Bay of Bengal to study the provenance of dust and riverine sediments, respectively. One outcome of the study may be the development of a routine low cost Argon dating method for ODP samples.
