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放射性（K/Ar）方法，用于确定海洋粘土矿物的年龄，用于在一系列地质和海洋学应用中进行物源示踪研究。 该方法将被应用于一套样本从北太平洋和孟加拉湾的灰尘和河流沉积物的来源，分别研究。 这项研究的一个成果可能是开发一种用于ODP样品的常规低成本氩测年方法。

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.
