Deciphering the past history of rocks and what they might reveal about the Earth’s future is a key part of geology, and tools such as Ion Probes can be used by Earth Scientists to extract valuable information about a rock’s past. Today’s Imaggeo on Monday’s image was acquired by Sarah Glynn, a researcher at the University of the Witwatersrand, in South Africa, who was analysing a potential calcite ...[Read More]

GeoTalk: What can you learn from a human hair?

May 2, 2014

Jim Ehleringer is Director of the Stable Isotope Ratio Facility at the University of Utah in Salt Lake City in the US. In the past few years he has been developing a method for deducing people’s diets and travel history from a sample of their hair. Here, he talks to the EGU press office about his research. Thanks for agreeing to chat, Jim. Can you tell me a bit about how your project started? This ...[Read More]

GeoTalk: Connecting geoscience and archaeology with Sophie Gangl

This week in GeoTalk, we’re talking to Sophie Gangl, a masters student from the University of Natural Resources and Life Sciences (BOKU), Vienna. Sophie tells us about the intersecting fields of geoscience and archaeology, and shares the benefits of presenting postgraduate projects at an international conference. Hi Sophie, can you tell us a little about yourself and what you’ve been investigating ...[Read More]

Geosciences Column: Dating a bivalve

August 16, 2013

Just as the rings on a tree can be used to determine its age, the bands on a bivalve’s shell can tell us the how long it’s been around for. Warm, food-filled waters lead to greater growth in the summer and low plankton abundance (the principle food source for filter-feeding molluscs) leads to limited growth during the winter months – hence the banding. But pinning down the age of a bivalve m ...[Read More]
