There is more oxygen in the core of Earth than originally thought. Geologists have discovered some new findings about Earth's core and mantle by considering their geophysical and geochemical signatures together.
The 25th Goldschmidt Conference welcomed more than 3,700 delegates to the beautiful city of Prague last month. EAG and GS thank everyone who attended and the sponsoring organizations for their support. A detailed report of the conference is now available, as well as photos and videos of the plenary lectures. To help us make future Goldschmidt conferences even better, we ask for your feedback in the Goldschmidt2015 questionnaire.
Analab manufacture corrosion resistant laboratory appliances such as
acid vapour cleaning stations, hotplates, and sample preparation
devices. Our devices can be used with a wide range of acids and bases
(HF to NH4OH). We are represented in North America by Isomass
Please visit us at Goldschmidt Aug 16 – 21/15 in Prague.
The Goldschmidt2016 Science Committee is asking the community to suggest sessions for the 2016 conference in Yokohama, Japan. These suggestions will be the building blocks of the final session list. The deadline for submissions is Oct. 31. Learn more and contribute a suggestion.

University of Cincinnati
University of Cincinnati scientists are reporting a significant finding that could open up entirely new explorations in the fields of ecology and paleoecology. A mathematical analytical tool that was designed to predict a common elemental signal in surface water – resulting in significant savings compared with traditional field surveys – also is effective at predicting values for a wide range of materials, and is in fact most successful when applied to the bones and teeth of mammals.
Heavy metal pollution, typically caused by mining and smelting, is a major threat to human health - but the problem is seemingly not new.
Researchers have found the earliest signs of such man-made pollution in caves in Spain and Gibraltar that date from at least the Middle Palaeolithic.
