STRONTIUM is a major trace element in limestones and dolomites, in which it appears to be housed in the lattices of the carbonate minerals. With relatively few exceptions, strontium ranges from 10,000 ...

Marine barite extracted from deep-sea sediment cores, seen here in a scanning electron microscope image, provides a record of variations in ocean chemistry over geologic time. (Image by Adina Paytan) ...

Strontium isotope geochemistry plays a pivotal role in elucidating Earth’s dynamic processes. By utilising both stable (δ88/86Sr) and radiogenic (87Sr/86Sr) isotopic systems, researchers are able to ...

To really get to know someone, you have to get inside their head. And it’s the same for salmon. In their inner ear canals, just behind their eyes, sit small chunks of calcium carbonate called otoliths ...

Vishnu Chemicals Limited announced the commencement of commercial production of Strontium Carbonate at its Atchutapuram unit, Visakhapatnam, Andhra Pradesh, effective August 20, 2025. The announcement ...

A new analysis of strontium isotopes in marine sediments has enabled scientists to reconstruct fluctuations in ocean chemistry related to changing climate conditions over the past 35 million years.
