Isoscapes in Food Science

In the food industry, certain products and ingredients are more highly valued when they originate from specific regions of the world. Given the importance of designating an origin to products, geochemical fingerprinting can be used to identify product origin.

U-Th Dating in Archaeology

Uranium-Thorium (U-Th) dating is a radioactive method to date a variety of carbonate samples, including corals, cave deposits, cave artwork, shells, foraminifera and bone.

Strontium & Neodymium Case Study: Connecting Atmospheric Dust to Source Region

The concentration, composition and circulation of atmospheric dust can play an important role in the global radiation budget. Sr-Nd-Hf isotopes are inherent in many geological settings and have been used to track the origin of sediments and dust.

Isotopes in Petroleum Exploration (Pb-Sr) and Verification (14C)

In petroleum exploration, it is vital to be able to interpret and date key occurrences within petroleum systems – including petroleum generation and alteration (post-generation). For example, identifying and dating the occurrence of certain authigenic minerals (e.g. carbonate cements) can provide information on when and where oil is likely to accumulate to aid in targeting exploration.
