Use of heavy liquid density separation to remove pyrite from sediment samples for radiocarbon dating

Proske, Ulrike; Wood, Rachel; Fallon, Stewart; Stevenson, Janelle

Description

Sample preparation protocols for concentrating organic material from sediments for radiocarbon dating often include a large number of steps and the use of hazardous chemicals. Thus, these protocols are often problematic for pollen-poor sediments as material can get lost or may become degraded. Pyrite in samples for radiocarbon dating hinders an effective graphitisation process and thus needs to be removed during sample preparation. Standard protocols require the use of nitric acid, a strong...[Show more]
