Sr Isotopes

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 Stable 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.

ACRA Webinar on Bones: Isotopes in Dating, Diets and Migration Studies

Bones: Isotopes in Dating, Diets and Migration Studies
Live Webinar: April 14, 2022 – 2:00 PM to 3:30 PM Eastern Time

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 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.

Corals: A marine recorder of climate variability

Before a time series of climate variability can be developed, the coral growth bands must first be dated. Corals can be dated using radiocarbon dating, U-Th dating and/or Sr-Sr dating.

Sediments Webinar: Dating & Environmental Reconstructions

Isobar Science and Beta Analytic’s webinar on sediments focuses on dating & environmental reconstructions. This complimentary webinar takes place on December 2, 2021 at 12:00 PM Eastern Time (US and Canada).

Analysing lake sediment cores: from dating to paleoclimate reconstructions

Sediments used for climate and environmental reconstructions come in many different forms (including lacustrine, marine, peat, terrestrial and aeolian deposits) and can be characterized by their grain size, shape, sedimentary facies, chemical and biological composition and accumulation/sedimentation rate.
