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.

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.

Isoscapes: connecting samples to place

Maps demonstrating variability in specific isotopes across a landscape have been produced in varying spatial resolutions (local, regional, global) – known as isoscapes.

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.

Using Strontium Isotopes to Track Animal Origin and Migration

The details of animal origin and migratory routes through terrestrial and aquatic systems can be traced through the analysis of various stable isotopes including strontium, neodymium, carbon and oxygen.

Isobar’s Webinar: Migration Studies & Geographic Origin

Isobar’s webinar on migration studies and geographic origin will focus on lead isotopes for tracking origin and trade of metal artifacts in addition to using strontium isotopes to track diet.

Tracing Volcanic Eruptions using Strontium Isotopes

Volcanic eruptions are significant geological events with far reaching implications. The analysis of isotopes in various sample types can provide information on the timing and magnitude of past volcanic eruptions.

Strontium Isotopes (87Sr/86Sr) for Geochronology

Strontium ratios have varied in the world’s oceans through time as a result of fluctuations in strontium type and availability, often resulting from weathering of continental materials as well as volcanic activity at the mid-oceanic ridge. Such variations are recorded in oceanic sediment as a result of the precipitation of minerals from seawater, which has been used as a basis for the 87Sr/86Sr marine curve.
