Application of Double and Triple Dating of Zircons to Sediment Provenance Studies and to Quantifying Recycling in Sedimentary Rocks

双重和三重测年是令人兴奋的新ANU-Yale突破，可用于更准确地确定河流和沉积岩中沉积物的来源，而不是使用现有技术。 它们在侵蚀研究、追踪钛矿床中重矿物的来源以及确定石油沉积序列的来源方面具有基本的应用。 在有利的条件下，双测年法也可用于测定缺乏化石的沉积物的年代，这在石油勘探中有直接的应用。

Double and triple dating are exciting new ANU-Yale breakthroughs that can be used to more accurately identify the source of sediment in rivers and sedimentary rocks than is possible using existing techniques. They have fundamental applications in the study of erosion, tracing the source of heavy minerals in titanium deposits and in determining the source of sedimentary sequences that host oil. Under favourable circumstances double dating can be used also to date sediments that are devoid of fossils, which has direct application in oil exploration.
