The study of isotopes in soils has become an essential tool in understanding both geological time scales and contemporary environmental processes. By utilizing various isotopes, researchers can glean information about such varied topics as soil formation, nutrient cycling, and past climate conditions. This article focuses on prominent isotopic systems employed in soil studies, including radiocarbon […]
The analysis of archaeological artifacts through isotopic techniques has become a cornerstone of modern archaeological research. These methods allow for the investigation of the origins, movements, and interactions of ancient materials, thereby illuminating the complex relationships between humans and their environments over millennia. By employing various isotopic signatures, researchers can glean insights into trade networks, […]
Water’s continuous movement and flow of water across landscapes contribute
to and provide important clues into the intricacies of biogeochemical cycles
at various spatial and temporal scales.
Limestone is a granular sedimentary rock predominantly composed of
calcium carbonate (CaCO3), which commonly forms along shallow ocean
water beds from fossilized shells and exoskeletons of marine organisms.
Gypsum is a relatively soft and common mineral made up of hydrous
calcium sulfate (CaSO4-2H2O). Whilst pure gypsum crystals are transparent
(often with a pearly or vitreous luster), they can appear opaque and colored
due to the inclusion of other materials (e.g. sand).
Strontium dating (as enabled by the 87Sr/86Sr ratio of marine carbonates) can be used to date various marine samples based on the premise that the mixing of oceanic strontium occurs relatively rapidly through time compared to the residence time of oceanic strontium.
Ice core records are an important foundational archive for paleoclimatology. Through them scientists have reconstructed high resolution atmospheric CO2 and temperature records covering hundreds of thousands of years.
Archaeological pottery samples can be provenanced through the analysis of the origin of its component clay and temper.
Bones and teeth are relatively common within the archaeological and paleontological record due to the tendency for high preservation after burial.
Isobar Science is now offering a Strontium Chronology Service for dating marine carbonate samples. Strontium Isotope Ratios (87Sr/86Sr) within the ocean have varied through time, creating a predictable seawater curve that can be used for dating calibration.
